[0001] Cross - reference to related applications
[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 373,760, filed on August 29, 2022, and this application is its U.S. non - provisional patent application, the entire content of which is incorporated herein by reference. Technical field
[0003] The present disclosure relates to observation optical mirrors with integrated display systems. In one embodiment, the observation optical mirror has an active display system that generates an image and projects the image onto a first focal plane of the optical system. In yet another embodiment, the observation optical mirror has a system or device configured to track magnification settings. Background art
[0004] Sighting scopes have been in use for over a century. Although the quality and features of these devices have been greatly improved over the years, the core components used in their design, manufacture, and use (and the limitations of these components) are still very similar today to what they were 100 years ago. A sighting scope creates a magnified or non - magnified image of a scene away from the shooter on the focal plane, which coincides with calibration features or a reticle. The reticle consists of lines or materials deposited as a pattern on a glass surface, and it serves as a calibration reference that corresponds to the trajectory of the rifle to which it is attached. The reticle can also have specific features included to assist the shooter in distance judgment and compensating for bullet deviation at different distances.
[0005] Adjustment knobs are also used to make adjustments to the reticle position relative to the target to compensate for bullet deviation. This is a very well - developed and reliable system that can be used by experienced and skilled shooters to make challenging long - range shots. With the aid of a laser rangefinder (LRF) and a ballistic computer, as well as meticulous attention to detail, experienced shooters can routinely hit targets at the maximum effective range of their firearms by making the necessary mechanical adjustments to the firearm and / or performing the correct holds on the reticle pattern.
[0006] Although this system works well, there is always a desire to improve the system. In particular, it is desirable to reduce the complexity involved in hitting long - range targets. To effectively hit a long - range target, a large amount of information based on each shot is required, and the shooter must be able to process this information and make correct judgments and calculations in real time. In addition to the sighting scope, the shooter also needs other tools to ensure an accurate shooting position. For example, a bubble level needs to be mounted outside the sighting scope to ensure that the optical mirror is level before taking a shot. This requires the shooter to move his head away from the pupil of the optical mirror to check his level.
[0007] A laser rangefinder and a ballistic computer are also required to measure the target distance and calculate the bullet trajectory. This again requires the shooter to pay attention to the external device and then remember the data when making the necessary adjustments. If a laser rangefinder mounted on the weapon is used, the shooter needs to take special care to ensure that the calibration points of the optical sight exactly correspond to those of the LRF.
[0008] In addition, it is not unimportant for the use of optical sights that they are only useful during the day. Once night begins to fall, thermal and / or night vision devices must be attached to the weapon in front of the optical sight. These devices capture other forms of radiation that are invisible to the human eye due to their low wavelength or intensity. These devices then recreate an image of the scene or enhance it and re-image the scene onto the objective lens of the optical sight. These devices are effective and necessary for low light conditions, but they are also heavy and large.
[0009] In the specific case of a thermal imaging device, the thermal scene is imaged onto a special thermal sensor through an infrared optical lens. The image is then recreated on a microdisplay, and the microdisplay in turn re-images it into the objective lens of the optical sight using a visible optical system. The two independent optical systems required to achieve this result in a rather large, heavy, and expensive device.
[0010] With the progress of technology, a certain degree of system integration is required to reduce the heavy processing requirements on the shooter. This integration is also needed to reduce the traditionally rather long "time to hit" when multiple devices need to be referenced and calculations and adjustments must be made. Finally, through a more integrated solution, the size and weight of the additional devices required for effective use of the optical sight in low light conditions can be reduced.
[0011] The ability to accurately track and communicate the magnification setting of the optical sight to the user of the optical sight would be a significant advancement. In addition, it is also useful to display information to the user at a specific magnification setting.
[0012] Accordingly, there is still a need for an observation optical sight that can project magnification setting information into the first focal plane of the optical system. The devices, systems, and methods disclosed herein address all of these drawbacks in an innovative way. SUMMARY OF THE INVENTION

[0143] The devices and methods disclosed herein will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the disclosure are shown. However, the devices and methods disclosed herein may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0144] Those skilled in the art will understand that the set of features and / or capabilities can be easily adjusted in the context of standalone weapon sights, front or rear clip-on weapon sights, and other arrangements of optical weapon sights already deployed. In addition, those skilled in the art will understand that various combinations of features and capabilities can be incorporated into additional modules for retrofitting any type of existing fixed or variable weapon sight.
[0145] It should be understood that when an element or layer is referred to as "on another element or layer", "connected to" or "coupled to" another element or layer, it can be directly on the other element or layer, connected or coupled to the other element or layer. Alternatively, there may be intervening elements or layers. In contrast, when an element is referred to as "directly on another element or layer", "directly connected to" or "directly coupled to" another element or layer, there are no intervening elements or layers.
[0146] The same numerals always refer to the same elements. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0147] It should be understood that although the terms first, second, etc. may be used herein to describe various elements, components, regions, and / or parts, these elements, components, regions, and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, or part from another. Thus, a first element, component, region, or part discussed below may be referred to as a second element, component, region, or part without departing from the present disclosure.
[0148] For ease of description, spatial relative terms such as "below", "beneath", "under", "above", "over", etc. may be used herein to describe the relationship of one element or feature to other elements or features as shown in the figures. It should be understood that, in addition to the orientation shown in the figures, spatial relative terms are intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as "below" or "beneath" other elements or features will be oriented "above" the other elements or features. Thus, the exemplary term "below" can include both an orientation above and below. The device may be otherwise oriented (rotated 90 degrees or in other orientations), and the spatial relative descriptors used herein are to be interpreted accordingly.
[0149] I. Definitions
[0150] The numerical ranges in this disclosure are approximate, so values outside the range may be included unless otherwise indicated. The numerical ranges include all values from and including the lower and upper values, in increments of one unit, provided that there is at least a two-unit interval between any lower value and any higher value. For example, if a compositional, physical, or other property (such as molecular weight, viscosity, etc.) is from 100 to 1,000, it is intended to expressly enumerate all individual values (such as 100, 101, 102, etc.) and sub-ranges (such as 100 to 144, 155 to 170, 197 to 200, etc.). For ranges that include values less than 1 or ranges that include decimals greater than 1 (e.g., 1.1, 1.5, etc.), one unit is considered 0.0001, 0.001, 0.01, or 0.1, as appropriate. For ranges that include single digits less than 10 (e.g., 1 to 5), one unit is typically considered 0.1. These are just examples for specific uses, and all possible combinations of the values between the lowest and highest values listed should be considered to be expressly stated in this disclosure. Numerical ranges are provided in this disclosure for, among other things, the distance from the user of the device to the target.
[0151] As used herein, the term “and / or” in a phrase such as “A and / or B” is intended to include: both A and B; A or B; A alone; and B alone. Similarly, the term “and / or” in a phrase such as “A, B, and / or C” is intended to encompass each of the following embodiments: A, B, and C; A, B, or C; A or C; A or B; B or C; A and C; A and B; B and C; A alone; B alone; and C alone.
[0152] As used herein, “active display” includes image creation pixel modulation. In one embodiment, the active display is an emissive active display. Emissive active displays, including but not limited to organic light-emitting diodes (OLEDs) and light-emitting diodes (LEDs), have an image and a light source in a single device and thus do not require an external light source. This can minimize system size and power consumption while providing excellent contrast and color space. OLEDs are made of ultrathin organic semiconductor layers that light up when they are connected to a voltage (charge carriers are injected and the brightness is mainly proportional to the forward current). The main layers sequentially include several organic materials (e.g., charge transport, blocking, and emission layers—each layer is a few nanometers thick), which are inserted between the anode and the cathode. The terms “active display,” “digital display,” and “microdisplay” may be used interchangeably.
[0153] As used herein, a “positive image sleeve” is a protrusion from a positive image lens mount that engages a slot in a positive image tube and / or a cam tube or is used for a similar purpose. It may be integral with the mount or may also be detachable.
[0154] As used herein, a "positive image tube" is any structure or device having an opening for receiving a positive image lens mount.
[0155] As used herein, a "firearm" is a portable gun, a barreled weapon that fires more than one projectile, typically driven by the action of an explosive force. As used herein, the term "firearm" includes pistols, long guns, rifles, shotguns, carbines, automatic weapons, semi-automatic weapons, machine guns, submachine guns, automatic rifles, and assault rifles.
[0156] As used herein, an "integrated display system" refers to a system for generating an image. In one embodiment, the integrated display system includes an active display. In one embodiment, the integrated display system includes an active display and a condenser optic. In yet another embodiment, the integrated display system includes an active display, a condenser optic, and a reflective surface.
[0157] In one embodiment, the integrated display system can be used to generate a digital image through the active display and direct the digital image to the first focal plane of an optical system to simultaneously view the digital image and an image of an external scene. As used herein, an "aiming system" refers to one or more optical devices and other systems that assist a person in aiming a firearm or other tool.
[0158] As used herein, the term "mark" can include any one of a variety of visually perceivable lines, circles, dots, crosshairs, horseshoes, geometric shapes, characters, numbers, letters, marks, or symbols.
[0159] As used herein, the term "passive reticle" refers to a reticle having fixed marks that cannot be changed by the user. Representative examples of passive reticles are etched and filled reticles. Another example is a holographic reticle, where the user cannot change the marks. The passive reticle can be located in the first focal plane, the second focal plane, or both the first and second focal planes.
[0160] As used herein, the term "observation optic" refers to a device used by a shooter or observer to select, identify, or monitor a target. An "observation optic" can rely on visual observation of the target, or, for example, on infrared (IR) imaging, ultraviolet (UV) imaging, radar imaging, thermal imaging, microwave or magnetic imaging, including radiation such as X-rays, gamma rays, isotopes, and particle radiation, night vision, including vibration receivers for ultrasound, acoustic pulses, sonar, seismic vibrations, magnetic resonance, gravity sensors, broadcast frequencies including radio waves, television and cellular receivers, or other images of the target. The target image presented to the shooter by the "observation optic" device can be unaltered, or it can be enhanced, for example, by magnification, enlargement, subtraction, superposition, filtering, stabilization, template matching, or other means. The target selected, identified, or monitored by the "observation optic" can be within the shooter's line of sight, or tangent to the shooter's line of sight, or the shooter's line of sight can be blocked when the target acquisition device presents a focused target image to the shooter. The image of the target obtained by the "observation optic" can be, for example, analog or digital, and is shared, stored, archived, or transmitted within a network of more than one shooter and observer by, for example, video, physical cables or wires, IR, radio waves, cellular connections, laser pulses, optical, 802.11b, or other wireless transmissions using protocols such as html, SML, SOAP, X.25, SNA, etc., Bluetooth TM 、serial, USB, or other suitable image distribution methods. The term "observation optic" can be used interchangeably with "optical sight".
[0161] As used herein, the term "external scene" refers to a real-world scene, including but not limited to a target.
[0162] As used herein, the term "shooter" applies to an operator who fires a shot or an individual who observes the shot in cooperation with the operator who fires the shot.
[0163] II. Observation Optic
[0164] Figure 1A Shows a conventional design of a sighting scope, which is a representative example of an observation optic. Figure 1B Shows an exemplary observation optic 10 according to an embodiment of the present disclosure. Specifically, Figure 1B Shows a sighting scope. More specifically, the sighting scope 10 has a body 38 that encapsulates a movable optical element 15. The body 38 is an elongated tube that tapers from a larger opening at its front portion 40 to a smaller opening at its rear portion 42. An eyepiece 56 is attached to the rear of the body, and an objective lens 54 is attached to the front of the body. The central axis of the movable optical element defines the optical axis 44 of the sighting scope.
[0165] The elevation adjustment knob 12 and the windage adjustment knob 48 are two dials which are typically located in the outer central portion of the body 38. They are marked in increments by markings 20 on their outer periphery 11 and are used to adjust the elevation and windage of the movable optical element for changes in the point of impact. These dials project from the adjustment knob housing 50. The adjustment knobs are arranged such that the elevation adjustment knob rotation axis 46 is perpendicular to the windage adjustment knob rotation axis 52.
[0166] Figure 1C A cross-sectional view of the Figure 1B sight device is shown, which has the basic components of the optical system 14 and the movable optical element 15. As Figure 1C shown, the optical system 14 includes an objective lens system 16, an erecting system 25, and an eyepiece system 18. Figure 1C A sight having a body 38 is shown, but the optical system 14 can also be used in other types of sight devices. The erecting system 25 can be included within the movable optical element 15. The erecting system 25 can include a variable magnification lens element or a zoom element 25A. In Figure 1C , the movable optical element 15 also includes a condenser lens 22, as well as a first focal plane reticle 55 and a second focal plane reticle 57. In use, the adjustment of the adjustment knob assembly 28 and the adjustment knob screw 29 causes the adjustment of the movable optical element 15.
[0167] The movable optical element 15 is adjusted by rotating the adjustment knob assembly 28 one or more clicks. When the adjustment knob is rotated, the adjustment knob screw 29 moves into and out of the sight, which pushes the erecting tube. The erecting tube is spring-biased, so when the adjustment knob screw is adjusted, it positions the erecting tube against the bottom surface of the adjustment knob screw. The erecting tube provides a smaller view of the entire image. When the erecting tube is adjusted, the position of the reticle is modified relative to the image.
[0168] A reticle is a circular, planar or flat transparent panel or disk which is mounted within the sight body, perpendicular to the optical axis or the line of sight through the sight, and is located between the objective element 54 and the erecting lens element, typically at the position of the front focal plane of the optical system within what is considered to be the housing. In one embodiment, the reticle contains fine etched lines or thin line markings which include a central vertical thin line and a central horizontal thin line which intersect orthogonally or perpendicularly at the center point.
[0169] In one embodiment, as Figure 1DAs shown, the observation optical scope may have a parallax adjustment knob 70 or a focusing knob. Parallax occurs when the optical plane of the image of the target is not coplanar with the optical plane of the image of the reticle. Due to the offset between these two optical planes, when the shooter moves their eyes around the center of the reticle, the reticle may appear to move relative to the target. This parallax error can cause the point of impact to shift from the time of firing. By enabling the optical system to be adjusted to display the image of the target and the image of the reticle in the same optical plane, the parallax adjustment of the observation optical scope allows the shooter to eliminate optical errors at different distances. Parallax compensation neither changes the focus of the reticle nor the focus of the image; it simply moves the planes at which the two objects are focused so that they share the same plane (coincide).
[0170] As Figure 1D shown, the observation optical scope may have a side wheel mounted to the rotatable parallax adjustment knob 70. The larger the diameter of the side wheel, the more space is provided for the markings to be applied (such as distance markings), and it makes it easier for the shooter to rotate and read during use. The larger diameter of the side wheel is used to increase the accuracy and resolution of the range-finding markings.
[0171] Figure 1E A close-up view of the optical system 14 is shown in cross-section, showing how light passes through the optical system 14. The optical system 14 may have additional optical components, such as a condenser lens 22, and it is well known in the art that certain components, such as the objective lens system 16, erecting system 25, and eyepiece system 18, may themselves have multiple components or lenses.
[0172] In one embodiment, the observation optical scope may have a focusing unit having more than one adjustable lens for providing parallax adjustment. In one embodiment, the more than one adjustable lens is one or more parallax lenses.
[0173] In one embodiment, the focusing lens is located between the eyepiece and the objective lens. The relative distance between the focusing lens and the objective lens is adjustable for providing parallax adjustment. Additionally, the erecting lens is located between the eyepiece and the focusing lens. The relative distance between the erecting lens and the objective lens is adjustable to provide magnification adjustment.
[0174] III. Observation Optical Scope with an Active Display
[0175] In one embodiment, the present disclosure relates to an observation optical mirror with an active display that generates a digital image and projects the digital image into a first focal plane of the observation optical mirror. In one embodiment, the present disclosure relates to an observation optical mirror with an analog reticle and a digital image, including but not limited to a digital reticle visible to a user when observing through the observation optical mirror. In one embodiment, the observation optical mirror can be used with an external laser rangefinder having ballistic calculation capabilities.
[0176] In one embodiment, the observation optical mirror has a movable erecting tube, and the movable erecting tube has an analog reticle or a glass-etched reticle, which is mounted on the erecting tube in such a way that the analog or glass-etched reticle moves together with the erecting tube. In one embodiment, the digitally injected reticle does not move with the erecting tube. Therefore, the digital reticle is accurate regardless of the position of the adjustment knob or the erecting tube.
[0177] In one embodiment, the present disclosure relates to an observation optical mirror with a digital display that can be injected into a first focal plane of the observation optical mirror such that the image of the digital display on the first focal plane is independent of the movement of the erecting tube. In one embodiment, the display can provide the user with accurate ballistic holdover aiming points regardless of the position of the erecting tube / adjustment knob of the sight.
[0178] In one embodiment, the present disclosure relates to an observation optical mirror with aiming points that are agnostic to the position of the erecting tube and / or the adjustment knob of the observation optical mirror. In one embodiment, if the aiming point determined by the ballistics is outside the field of view of the erecting unit, the adjustment knob can be toggled to bring the aiming point determined by the ballistics into the field of view.
[0179] In one embodiment, the observation optical mirror has a main optical system and a second optical system. The main optical system includes: an objective lens system that focuses an image from a target downward onto a first focal plane (hereinafter referred to as the "FFP target image"); then an erecting lens system that inverts the FFP target image and focuses it onto a second focal plane (hereinafter referred to as the "SFP target image"); a beam combiner that is placed between the objective lens system and the FFP target image; and an eyepiece system that collimates the SFP target image so that it can be observed by the human eye.
[0180] In one embodiment, the second optical system has: an active display; and a lens system that collects light from the active display. The image from the digital display is directed to the beam combiner such that the target image from the objective lens system and the digital image can be combined at the first focal plane and observed simultaneously. In one embodiment, the second optical system can have a reflective material, including but not limited to a mirror.
[0181] Referring to the above description, the digital display is injected into the main optical system, between the objective lens system and the first focal plane, and then focused onto the first focal plane. At the first focal plane, the digital image from the digital display and the analog / glass-etched reticle attached to the erecting lens system share the same plane. However, the analog reticle is attached to the movable erecting lens system, while the image from the digital display is not attached to the movable erecting lens system. Therefore, if the erecting lens system is moved, the analog reticle will move, but the digital image will remain stationary.
[0182] In one embodiment, the observation optical mirror can be rigidly mounted to the firearm. In another embodiment, the laser rangefinder can be mounted to the firearm or the observation optical mirror. The laser rangefinder measures the distance to the target, calculates the trajectory for hitting the target, and provides this information to the active display, so that the correct aiming point can be displayed together with the impact point of the rifle bullet.
[0183] It is important that the digital image remains stationary because the laser rangefinder is rigidly attached to the observation optical mirror and its aiming point does not move. This allows the digital display to be digitally adjusted so that the digital laser indicator corresponds to the laser at the initial setting, and then the two will always remain aligned regardless of how the erecting lens system moves.
[0184] In addition, the firearm barrel is rigidly attached to the observation optical mirror, so the aiming point of the barrel will never change relative to the digital display. This allows the digital display to be digitally adjusted so that during the initial setting, the digital aiming point corresponds to the firearm barrel at its initial "zeroing" distance, and then the two will always remain aligned.
[0185] When shooting at a distance different from the initial zeroing distance is required, the laser rangefinder can measure the distance and then perform a ballistic calculation to determine the new position of the aiming point. This new aiming point position is always relative to the initial zeroing distance. Therefore, the sight only needs to adjust the digital display aiming point to correspond to the new aiming point.
[0186] Another advantage of this system is that since the digital aiming point is stationary, the user can easily test the accuracy of the adjustment knob for adjusting the position of the erecting tube on the observation optical mirror using a reticle with pre-determined marks at regular intervals. When the erecting tube moves, the reticle can be measured relative to the fixed digital aiming point to see if the adjustment dialed on the adjustment knob matches the amount of movement measured between the digital aiming point and the reticle attached to the erecting lens system.
[0187] IV. Observation Optical Mirror with a Base
[0188] In one embodiment, the present disclosure relates to an observation optical mirror, including but not limited to a telescopic sight, which has a first housing coupled to a second housing. In one embodiment, the first housing is a body. In yet another embodiment, the second housing is a base.
[0189] In one embodiment, the present disclosure relates to a telescopic sight that has a body and a base coupled to the body. In one embodiment, the base is separable from the body. In one embodiment, the base is attached to the bottom of the body. In one embodiment, a gasket is used to seal the body and the base.
[0190] In one embodiment, the present disclosure relates to a telescopic sight that has: a body having an optical system for generating an image of an external scene; and a base coupled to the body and having an integrated display system for generating a digital image and guiding the digital image to a first focal plane of the optical system, thereby providing simultaneous viewing of the digital image and the image of the external scene.
[0191] In another embodiment, the present disclosure relates to a telescopic sight that has: a body having an optical system for generating an image of an external scene; and a base coupled to the body and having an integrated display system with an active display for generating an image and guiding the generated image to a first focal plane of the optical system, providing simultaneous viewing of the generated image and the image of the external scene when viewed through an eyepiece of the sight body.
[0192] In a representative embodiment, Figure 2 A side view of a telescopic sight 200 having a body 210 and a base 220 is shown. In one embodiment, the base 220 is separable from the body 210. The base 220 is attached at one end of the sight body near the magnification ring 212 and at the other end of the sight body near the objective lens assembly 214. In one embodiment, the body 210 and the base 220 are made of the same material. In another embodiment, the sight body and the base are made of different materials.
[0193] In one embodiment, the base 220 is approximately the length of the erect image tube of the body.
[0194] In one embodiment, the base has an integrated display system that can generate and display scene, geographic, and ballistic information in the first focal plane of the observation optic, including but not limited to: real-time ballistic solutions; next-round ballistic corrections through in-flight tracer detection and tracking; weapon pointing angle tracking using integrated high-performance inertial sensors; precise pointing angle comparison for advanced ballistic aiming and corrections; target position and name; pressure, humidity, and temperature; the device can process self-destruct and situation awareness data and observe during aiming; reticle aiming corrections outside the field of view of the optic to facilitate ballistic drop corrections at long ranges; weapon, projectile, and environmental characteristic data.
[0195] In one embodiment, the observation optic has one or more of the following capabilities and / or components: more than one microprocessor, more than one computer, a fully integrated ballistic computer; an integrated near-infrared laser rangefinder; GPS and digital compass integrated with the observation optic and capable of fully coordinating target position and name; sensors for pressure, humidity, and temperature integrated with the observation optic and capable of automatically incorporating this data into ballistic calculations; traditional observation optic capabilities under all conditions, including zero-power-off mode; wired and wireless interfaces for communication of sensor data, environmental data, and situation awareness data; the ability to support digital interfaces such as Personal Network Node (PNN) and Soldier Radio Waveform (SRW); integrated tilt sensitivity relative to vertical for ballistic corrections for uphill and downhill shooting azimuths; an integrated imaging sensor; acquiring and processing target scene image frames; the ability to record the firing time history to apply cold-bore / hot-bore firing corrections in an automated manner; and a built-in backup optical range estimation ability with automatic angle-to-linear dimension conversion.
[0196] In one embodiment, the observation optic can communicate wirelessly with more than one device. In another embodiment, the observation optic can communicate with more than one device via physical cables.
[0197] A. Body
[0198] In one embodiment, the body is in the shape of an elongated tube that tapers from a larger opening at its front to a smaller opening at its rear, with an eyepiece attached to the rear of the elongated tube and an objective lens attached to the front of the elongated tube. In one embodiment, the first housing is the body of the sight.
[0199] In one embodiment, the body has an observation input end and an observation output end, which can be along the observation optical axis 44 ( Figure 1B) Aligned and can be within the tube. The user's eyes can directly observe an object or target by looking through the input end, along the observation direct vision optical device, and out of the observation output end. The body may include an objective lens or lens assembly at the observation input end. The first focal plane reticle can be positioned along the observation optical axis A and spaced apart from the objective lens assembly.
[0200] In one embodiment, the photo or image inversion lens assembly can be positioned and spaced rearwardly along the observation optical axis A from the first focal plane reticle. The erect image tube with an erect image system is located within the body between the objective lens and the eyepiece to invert the image. This provides the correct terrestrial observation orientation for the image. The erect image system is typically contained within the erect image tube.
[0201] The inversion lens assembly or the erect image system may include more than one lens spaced apart from each other. The erect image system may include more than one movable optical element, such as: a focusing lens that can be moved along its optical axis to adjust the focus of the image; and a magnifying lens that can be moved along its optical axis to optically magnify the image at the rear focal plane, making the target appear closer than its actual distance. Generally, the erect image assembly includes a mechanical, electromechanical, or electro - optical system for driving the coordinated movement of more than one power - varying lens element of the focusing lens and the magnifying lens, thereby providing a continuously variable magnification range through which the erect image assembly generates a focused, erect image of a distant target at the rear focal plane.
[0202] Variable magnification can be achieved by providing a mechanism for adjusting the position of the erect image lenses relative to each other within the erect image tube. This is typically done by using a cam tube that fits closely around the erect image tube. Each erect image lens (or lens group) is mounted in an erect image lens mount that slides within the erect image tube. An erect image sleeve attached to the erect image lens mount slides in a straight groove within the body of the erect image tube to maintain the orientation of the erect image lens. The erect image sleeve also engages an angled or curved groove in the cam tube. Rotating the cam tube causes the erect image lens mount to move longitudinally within the guide tube, thereby changing the magnification. Each erect image lens has its own groove in the cam tube, and the configuration of these grooves determines the amount and rate of change of the magnification when the cam tube is rotated.
[0203] The aperture in the second focal plane can be positioned and spaced rearwardly along the observation optical axis A from the photo inversion assembly. The eyepiece assembly can be positioned and spaced rearwardly along the observation optical axis A from the aperture in the second focal plane at the eyepiece. The eyepiece assembly may include more than one lens spaced apart from each other. In some embodiments, the observation optical axis A and the direct vision optical device can be folded.
[0204] In one embodiment, the body has a beam combiner. In one embodiment, the beam combiner can be positioned on the observation optical axis 44 and optically coupled to the observation optical axis 44, as Figure 1BAs shown. In one embodiment, the beam combiner may be positioned near the observation optical reticle. In another embodiment, the beam combiner may be positioned near the observation optical reticle at the first focal plane.
[0205] In one embodiment, the beam combiner is located between the objective lens assembly and the first focal plane.

[0207] In one embodiment, compared to the eyepiece assembly in the main tube of the observation optical mirror, the body has a beam combiner positioned closer to the objective lens assembly.
[0208] Figure 3 A side cross-sectional view of a sighting scope 300 having a body 210 and a base 220 is shown. As shown, the sighting scope 300 has an objective lens assembly 310, a beam combiner 320, a first focal plane 330, a second focal plane 350, and an eyepiece assembly 360. The beam combiner 320 is located between the objective lens assembly 310 and the first focal plane 330.
[0209] In one embodiment, the observation optical mirror 400 may have a body 210 that is longitudinally dissected to allow the relevant lenses and circuits to be assembled in the base 220. Figure 4 is a representative example of the longitudinally dissected main tube 210 of the sighting scope 400. Figure 4 Depicts the parting line 410 of the longitudinally dissected main tube. A crack 420 in the bottom side of the body 210 allows the coupling of the base 220 having an integrated display system.
[0210] In one embodiment, the bottom side of the body has a longitudinal crack. In one embodiment, the longitudinal crack is approximately the length of the base coupled to the body.
[0211] In one embodiment, the body does not have an active display.
[0212] 1. Beam combiner
[0213] In one embodiment, the body of the observation optical sight has a beam combiner. In one embodiment, the beam combiner is one or more prisms (the prisms form the beam combiner). In another embodiment, the body of the sighting scope has a beam combiner that combines an image generated from an integrated display system with an image generated from the observation optical sight along the observation optical axis of the sighting scope. In one embodiment, the integrated display system is located in a housing that is separate and distinct from the body. In one embodiment, the integrated display system is located in a base that is coupled to the first housing or the body. In one embodiment, the integrated display system is located in a cavity of the base that is connected to the first housing or the body.
[0214] In one embodiment, the beam combiner is used to combine a generated image from an integrated display system with an image from an optical system for observing an external image, wherein the optical system is located in the body of the sighting scope, in front of the first focal plane in the body, and then the combined image is focused onto the first focal plane such that the generated image and the observed image do not move relative to each other. In the case where the combined image is focused onto the first focal plane, the calibration reference generated by the integrated display system is accurate regardless of the adjustment of the movable erecting system.
[0215] In one embodiment, the beam combiner can be aligned with the integrated display system along the display optical axis and is positioned along the observation optical axis of the observation optical sight of the body of the sighting scope, thereby allowing the image from the integrated display to be directed onto the observation optical axis and combined with the field of view of the observation optical sight in an overlapping manner.
[0216] In another embodiment, the beam combiner and the integrated display system are located in the same housing. In one embodiment, the beam combiner is approximately 25 mm from the objective lens assembly.
[0217] In one embodiment, the beam combiner is approximately 5 mm from the objective lens assembly. In one embodiment, the beam combiner is positioned at a distance from the objective lens assembly, including but not limited to 1 mm to 5 mm, or 5 mm to 10 mm, or 5 mm to 15 mm, or 5 mm to 20 mm, or 5 mm to 30 mm, or 5 mm to 40 mm, or 5 mm to 50 mm.
[0218] In yet another embodiment, the beam combiner is positioned at a distance from the objective lens assembly, including but not limited to 1 mm to 4 mm, or 1 mm to 3 mm, or 1 mm to 2 mm.
[0219] In one embodiment, the beam combiner is positioned at a distance from the objective lens assembly, including but not limited to at least 3 mm, at least 5 mm, at least 10 mm, and at least 20 mm. In yet another embodiment, the beam combiner is positioned at a distance from the objective lens assembly from 3 mm to 10 mm.
[0220] In another embodiment, the beam combiner is about 150 mm from the eyepiece assembly. In one embodiment, the beam combiner is positioned at a distance from the eyepiece assembly, including but not limited to 100 mm to 200 mm, or 125 mm to 200 mm, or 150 mm to 200 mm, or 175 mm to 200 mm.
[0221] In one embodiment, the beam combiner is positioned at a distance from the eyepiece assembly, including but not limited to 100 mm to 175 mm, or 100 mm to 150 mm, or 100 mm to 125 mm.
[0222] In one embodiment, the beam combiner is positioned at a distance from the eyepiece assembly, including but not limited to 135 mm to 165 mm, or 135 mm to 160 mm, or 135 mm to 155 mm, or 135 mm to 150 mm, or 135 mm to 145 mm, or 135 mm to 140 mm.
[0223] In one embodiment, the beam combiner is positioned at a distance from the eyepiece assembly, including but not limited to 140 mm to 165 mm, or 145 mm to 165 mm, or 150 mm to 165 mm, or 155 mm to 165 mm, or 160 mm to 165 mm.
[0224] In one embodiment, the beam combiner is positioned at a distance from the eyepiece assembly, including but not limited to at least 140 mm or at least 145 mm or at least 150 mm or at least 155 mm.
[0225] In yet another embodiment, the body has a beam combiner, wherein the beam combiner is located below the elevation adjustment knob on the outer central portion of the mirror body.
[0226] In one embodiment, the beam combiner may have a partially reflective coating or surface that reflects and redirects at least a portion of the output from the integrated display system or the active display output onto the viewing axis of the observer's eye at the eyepiece, while still providing good transmission and perspective quality for the direct viewing optical path.
[0227] In one embodiment, the beam combiner can be a cube made of an optical material, such as optical glass or a plastic material with a partially reflective coating. The coating can be a uniform, neutral color reflective coating, or it can be customized with a polarization, spectral selectivity, or patterned coating to optimize the transmission and reflection characteristics in the eyepiece. The polarization and / or color of the coating can be matched to the active display. This can optimize the reflectivity and efficiency of the display optical path with a minimal impact on the direct viewing optical transmission path.
[0228] Although the beam combiner is shown as a cube, in some embodiments, the beam combiner can provide different optical path lengths for an integrated display system as well as for a direct-view optical device along the viewing optical axis A. In some embodiments, the beam combiner can be in the form of a plate, where a thin reflective / transmissive plate can be inserted across the direct-view optical path spanning the optical axis A.
[0229] In one embodiment, the position of the beam combiner can be adjusted relative to the reflective material to eliminate any errors, including but not limited to parallax errors. A screw system, a wedge system, or any other suitable mechanism can be used to adjust the position of the beam combiner.
[0230] In one embodiment, the position of the beam combiner can be adjusted relative to the erecting tube to eliminate any errors, including but not limited to parallax errors.
[0231] 2. Parallax System
[0232] In one embodiment, the body has a parallax adjustment system. In one embodiment, the parallax adjustment system uses means for connecting a focusing unit to a parallax adjustment element.
[0233] In one embodiment, compared to a conventional focusing unit and a beam combiner located in the space conventionally occupied by the focusing unit, the viewing optical mirror disclosed herein has a body that has a focusing unit closer to the objective lens end. In one embodiment, a connecting element connects the focusing unit to the parallax adjustment element.
[0234] In a typical sight, as Figure 5A and Figure 5B shown, the parallax knob 510 is connected to the focusing unit via a simple cross pin 520 that moves on a cam slot 530 in the parallax knob, converting the rotational movement of the knob into a linear movement within the focusing unit. However, in some embodiments disclosed herein, the focusing unit is shifted towards the objective lens side, and thus, a connecting means for connecting the focusing unit to the parallax adjustment element is required.
[0235] The parallax adjustment system can eliminate or reduce the parallax error between the image of the active display and the reticle in the body of the viewing optical mirror. The parallax adjustment system disclosed herein allows the viewing optical mirror to integrate the digital display image and the image of the external scene into the first focal plane (FFP) of the optical system without parallax error.
[0236] In another embodiment, the focusing unit is closer to the objective lens side of the main body compared to the focusing unit of a conventional sight. In one embodiment, compared to the focusing unit of a conventional sight, the focusing unit is displaced and closer to the objective lens by about 5 mm to about 50 mm. In one embodiment, compared to the focusing unit of a conventional sight, the focusing unit is displaced and closer to the objective lens by at least 20 mm. In one embodiment, compared to the focusing unit of a conventional sight, the focusing unit is displaced and closer to the objective lens by at least 10 mm. In yet another embodiment, compared to the focusing unit of a conventional sight, the focusing unit is displaced and closer to the objective lens side by no more than 50 mm. In one embodiment, compared to the position of the focusing unit in a Vortex Diamondback sight, a Vortex Viper sight, a Vortex Crossfire sight, or a Vortex Razor sight, the focusing unit is displaced and closer to the objective lens assembly by 30 mm.
[0237] In one embodiment, compared to the focusing unit of a conventional sight, the focusing unit is displaced and closer to the objective lens, including but not limited to being closer to the objective lens side of the observation optical lens by 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, 31 mm, 32 mm, 33 mm, 34 mm, 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, and 40 mm.
[0238] In one embodiment, a device connects the displaced focusing unit to the adjustment knob. In one embodiment, the device allows for the remote positioning of the parallax adjustment lens located in the focusing unit. In one embodiment, the mechanical device is a push rod, a rod, or a shaft.
[0239] In one embodiment, the length of the rod is about 5 mm to about 50 mm. In one embodiment, the length of the rod is at least 20 mm. In one embodiment, the length of the rod is at least 10 mm. In yet another embodiment, the length of the rod does not exceed 50 mm.
[0240] In one embodiment, the length of the rod is 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, 31 mm, 32 mm, 33 mm, 34 mm, 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, and 40 mm.
[0241] Figures 5C - 5FA representative schematic diagram of a parallax adjustment system in the main tube 210 of an observation optical scope according to an embodiment of the present disclosure. As Figure 5C shown, a device 530 such as a rod or shaft connects a focusing unit (parallax lens) 535 that has moved closer to the objective end of the observation optical scope to a parallax cam track pin 540 within a parallax adjustment knob assembly. The shifted position of the parallax lens provides the necessary space for the prism in front of the first focal plane. One end of the linkage is coupled to the focusing unit and the other end of the linkage is coupled to the cam pin.
[0242] Figure 5D The device 530 that connects the focusing unit 535 having a parallax lens to the parallax cam track pin 540 is shown, where the parallax cam track pin 540 moves within a cam track 545 of a parallax adjustment assembly 550. In one embodiment, the parallax adjustment assembly 550 has a rotatable element for moving the cam pin and adjusting the parallax lens.
[0243] As Figure 5E shown, to provide space for a beam combiner (prism) within the body of the observation optical scope, the focusing unit is shifted closer to the objective assembly. Accordingly, a mechanism for connecting the focusing unit to the parallax knob assembly is needed. The connecting device 530 connects the focusing unit to a cam pin 540 that moves within a cam groove of the parallax knob assembly 560.
[0244] As Figure 5F shown, the cam pin 540 moves within a cam groove 545 of the parallax knob assembly 560, allowing adjustment of the focusing unit via the parallax knob assembly.
[0245] In one embodiment, the shifted focusing unit having a parallax lens provides space within the body for integrating the beam combiner before the first focal plane of the objective system.
[0246] In one embodiment, the beam combiner within the body of the sight disclosed herein is located in the space where the focusing unit is typically mounted in a conventional sight.
[0247] In one embodiment, the present disclosure relates to an observation optical scope, comprising: (a) a main tube; (b) an objective system coupled to a first end of the main tube; (c) an eyepiece system coupled to a second end of the main tube; (d) a focusing unit located between the objective system and the beam combiner, wherein the beam combiner is located between the focusing unit and a first focal plane reticle; and (e) a rod that connects the focusing unit to a parallax adjustment element. In one embodiment, the rod connects the focusing unit to a cam pin of the parallax adjustment element. In some embodiments, the parallax adjustment element has a knob.
[0248] 3. Magnification Tracking System
[0249] In one embodiment, the present invention relates to an observation optical mirror and a method for tracking the magnification setting of the observation optical mirror, wherein the components of the tracking mechanism are reliable, completely transparent to the operator, and environmentally protected.
[0250] When the reticle is located in the first focal plane, the reticle is located in front of the erecting system, so the reticle changes proportionally with the change in the lens position, thereby generating a magnified image. The erecting system changes its position by using a magnification ring, which is located on the outer part of the telescopic sight near the eyepiece housing. Generally, the magnification ring is screwed to the outer erecting sleeve, and when rotated, it forces the outer erecting sleeve to rotate together with the magnification ring, thereby causing the cam groove to change the position of the zoom lens located in the erecting system. When a digital image is projected onto the first focal plane, it is necessary to scale the image by means of the reticle scaling so that the digital image is usable.
[0251] The magnification adjustment mechanism is coupled to a varifocal lens or a zoom lens element, which provides the ability to adjust the optical magnification of the image of a distant object.
[0252] In one embodiment, as Figure 6 shown, the potentiometer cursor 610 is located on the outer diameter of the outer erecting sleeve 620. The potentiometer cursor contacts a film potentiometer 710 located on the inner diameter of the main body 210 of the telescopic sight (see Figure 7 ).
[0253] As Figure 8 shown, in one embodiment, the potentiometer cursor 610 is a leaf spring having two contact points to ensure its contact with the film potentiometer 710. The leaf spring is located between the outer erecting sleeve 620 and the inner erecting tube. The potentiometer cursor 610 is located on the inner diameter of the telescopic sight on the opposite inner walls of the magnification ring groove screw 820. The potentiometer cursor 610 is fixed to the inner side of the barrel of the sight using an adhesive.
[0254] In one embodiment, the potentiometer cursor has the ability to lie completely flat on the outer diameter of the outer erecting sleeve. In one embodiment, the potentiometer cursor is built into the outer erecting sleeve.
[0255] In one embodiment, the potentiometer cursor is not placed on Figure 8 the magnification ring 810.
[0256] The magnification tracking system disclosed herein is located internally and no part is exposed to the environment, which provides several advantages. First, the system is internal, so no sealing is required to protect the cursor / erecting system from the environment. Second, when the erecting system is installed in the telescopic sight, the magnification tracking system is completed. This eliminates the possibility of debris entering the system through the screw holes on the outside of the magnification ring.
[0257] In one embodiment, the present disclosure relates to a system for tracking the magnification setting of an observation optical mirror, where the system uses a sensor and materials with different degrees of light reflectivity / absorptivity. In one embodiment, the sensor is located in the base of the observation optical mirror, where the base is coupled to the body of the observation optical mirror, and the materials are located in the body of the observation optical mirror.
[0258] In one embodiment, the present disclosure relates to an observation optical mirror having a body that includes an erecting tube with an erecting lens system, a cam tube or sleeve surrounding or encapsulating the erecting tube, materials with different light reflectivities / absorptivities coupled to the cam tube, and a base coupled to the body, where the base has an integrated display system and a photoelectric sensor for detecting the light reflectivity / absorptivity from the materials. In one embodiment, the base has a printed circuit board or a microprocessor for communicating with the photoelectric sensor and one or more microcontrollers or electronic controllers.
[0259] In one embodiment, the observation optical mirror has: a body having a magnification adjustment ring for adjusting the optical magnification of an image; and a base coupled to the body, having an integrated display system, a microprocessor, and a system for transmitting the magnification setting of the optical mirror to the microprocessor, where the microprocessor communicates with the active display of the integrated display system.
[0260] In one embodiment, the present disclosure relates to a system for tracking the magnification setting of an observation optical mirror without a mechanical link between the moving components of an optomechanical system and a sensing device. The magnification tracking system disclosed herein is embedded in a base coupled to the body of the observation optical mirror, and there is no mechanical link between the fixed and moving parts of the system.
[0261] In one embodiment, the present disclosure relates to an observation optical mirror having a body that has an erecting tube housing an erecting lens assembly and a cam sleeve surrounding the erecting tube, and materials with different light absorptivities / reflectivities, and a base coupled to the body, where the base has a photoelectric sensor. In one embodiment, the materials with different light absorptivities / reflectivities surround the cam sleeve at an end of the cam sleeve near the magnification adjustment ring of the body. In one embodiment, the photoelectric sensor is located below the materials with different light absorptivities / reflectivities on the cam sleeve.
[0262] When the operator / user rotates the magnification adjustment ring 212 of the observation optical mirror, the external cam sleeve rotates, which moves two lens units, thereby changing the effective optical magnification of the sight.
[0263] In one embodiment, the cam sleeve has materials with different light reflectivities / absorptivities. In one embodiment, the materials are fixed to the outer diameter of the cam sleeve.
[0264] In one embodiment, the material is a strip of material. In one embodiment, the material is approximately 10 mm wide and 40 mm long. In one embodiment, the first side of the material has an adhesive for attaching it to the outer cam sleeve. In another embodiment, the other side of the strip has a printed grayscale gradient such that when an LED is pointed at it, different amounts of light are reflected depending on the portion of the gradient exposed to the LED.
[0265] In one embodiment, the PCB has an LED and a photoelectric sensor. In one embodiment, the LED and the photoelectric sensor are located directly below the gradient strip attached to the outer diameter of the outer cam sleeve. The LED illuminates the gradient strip, and the photoelectric sensor receives a portion of the light reflected from the gradient strip and can then send a signal to the microcontroller, where the intensity of the signal varies with the amount of light detected.
[0266] When the operator rotates the magnification adjustment ring, another portion of the gradient strip is exposed to the LED and the photoelectric sensor, thereby changing the intensity of the signal sent to the microcontroller. Therefore, it is possible to track the optical magnification setting of the system by correlating the optical magnification setting of the system with the amount of light detected by the photoelectric sensor.
[0267] Figure 65 A side view of a 1-8x telescopic sight 6500 having a body 6502 and a base 6505 coupled to the body 6502 is shown. The magnification adjustment ring 6510 can be seen on the right side of the image.
[0268] Figure 66 A side view of the telescopic sight 6500 is shown, where the body of the telescopic sight is hidden and the outer cam sleeve 6610 is exposed, and the outer cam sleeve 6610 rotates with the magnification adjustment ring 6510, thereby changing the magnification setting.
[0269] Figure 67 A view of the base 6505 of the observation optical mirror 6500 having a printed circuit board 6710 is depicted, and the printed circuit board 6710 includes a photoelectric sensor and an LED 6720 for measuring the position of the reflective gradient material of the outer cam sleeve attached to the body. The outer cam sleeve and the associated optical system are hidden in this image.
[0270] Figure 68 Is an exploded view of the printed circuit board 6710, the photoelectric sensor, and the LED 6720, where an analog visual cone is drawn to show the light reception angle of the photoelectric sensor.
[0271] Figure 69 and Figure 70 is an image of a photoelectric sensor and an LED 6720 that work in cooperation with a reflective gradient strip 6910 attached to an external cam sleeve 6610 to measure the magnification setting of an optical mirror. The figure shows the gradient strip 6910, which has 4 specific parts with different reflectivities, but it should be noted that the reflectivity of the strip can vary infinitely. The gradient strip 6910 is coupled to the cam sleeve at a part of the cam sleeve near the magnification adjustment ring. The printed circuit board 6710 is located in the base 6505, which is coupled to the body of the observation optical mirror. The LED and the photoelectric sensor 6720 on the PCB 6710 are located below the gradient strip 6910.
[0272] In one embodiment, the present disclosure relates to an observation optical mirror, which includes: a body having a first end and a second end and having a central axis; an objective lens system disposed within the body; an eyepiece disposed within the body; an erecting tube disposed within the body and having an erecting lens system; the objective lens system, the eyepiece, and the erecting lens system form an optical system having a first focal plane and a second focal plane, the first focal plane being close to the objective lens system, and the second focal plane being close to the eyepiece; a cam sleeve surrounding the erecting tube, the cam sleeve moving together with a magnification adjustment ring to adjust the optical magnification of the image, a material having different degrees of light absorption / reflectivity coupled to the cam sleeve; and a base, coupled to the body, and having a photoelectric sensor for detecting light from the material, a microprocessor communicating with the photoelectric sensor, and an active display communicating with the microprocessor, the active display generating an image based on the magnification setting and projecting the generated image onto the first focal plane of the observation optical mirror. In one embodiment, the image generated by the active display is based on a signal obtained from the photoelectric sensor.
[0273] Transmitting the magnification setting to the microprocessor has many benefits, including but not limited to changing the reticle pattern based on the magnification setting, and automatically changing the font size of alphanumeric information as the magnification changes. Additionally, if multiple "display" pages are stored in a storage system, the microcontroller can automatically switch between "display" pages according to the magnification setting to provide the most relevant data to the operator.
[0274] 4. Additional Components
[0275] In one embodiment, the observation optical mirror can be controlled by a button integrated with the sight or an externally attached button.

The processor can be used to control various processes, algorithms, and / or methods in the operation of the sight. The processor can control the operation of the display system and / or the reticle. The processor can also receive inputs from a user interface, data input, memory, sensors, a position encoder associated with the position of an adjustable component (e.g., a vertical adjustment knob, a windage adjustment knob, or a parallax dial), and / or from other sources.

[0292] Figure 10 A top view of a sight 200 having a body 210 and a base 220 is shown. Figure 10 It is shown that the base 220 does not cause the sight to protrude or be disproportionate to a traditional sight in any position. The sight having a body and a base disclosed herein maintains the traditional, smooth design of the sight.
[0293] Figure 11 A base 220 attached to the body 210 of the sight is shown. The base 220 is aligned and flush with the outer edge of the body 210.
[0294] In one embodiment, as Figure 2 shown, the base with the integrated display system is coupled to the bottom side of the body 210 of the sight, with one end of the base being generally coupled to the power selection ring or magnification ring 212 of the body 210 and the other end of the base being coupled near the starting point of the objective lens assembly 214 of the body. In one embodiment, the base 220 is coupled to the body 210 by threaded fasteners, threadless integral and non-integral positioning and recoil transfer features, and elastomeric seals.
[0295] In one embodiment, the base can be expanded to house components required for generating a digital display, and then the base can be bolted to the body of the sight to form a fully enclosed and integrated system.
[0296] In one embodiment, the base and the body of the sight form a closed integrated system. In one embodiment, the base is coupled to the body without using a clamp designed to be easily removable.
[0297] In one embodiment, an observation optical sight having a body and a base coupled to the body can be coupled to a firearm without the need for a conventional sight ring. In one embodiment, the observation optical sight has a body and a base coupled to the body, wherein the bottom side of the base has a mounting rail.
[0298] In one embodiment, the base of the observation optical sight can include a mounting rail for mounting to a desired firearm, instrument, or device, and can have an adjustment mechanism that includes an elevation adjustment drum for adjusting the elevation position of the sight. A lateral adjustment mechanism is typically also provided for lateral adjustment. The adjustment mechanism can be covered with a protective cap.
[0299] In one embodiment, the top side of the base is coupled to the bottom side of the body of the observation optical sight, while the bottom side of the base has a mounting rail. In one embodiment, the top side of the base is coupled to a lateral crack in the bottom side of the body of the observation optical sight.
[0300] In one embodiment, the base includes an integrated display system for generating an image using an active display and guiding the image along a display optical axis so as to simultaneously overlay the generated image and an image of the external scene, wherein the generated image is injected into a first focal plane of the body of the observation optical sight.
[0301] In one embodiment, the base is separate and distinct from the laser rangefinder device. In one embodiment, the base is a device independent of the laser rangefinder device.
[0302] In one embodiment, the second housing or base is not an additional accessory. In another embodiment, the second housing or base is not coupled as an additional accessory near the eyepiece of the observation optical sight with an adapter.
[0303] In one embodiment, the end user cannot separate the second housing or base from the body. In one embodiment, the second housing or base cannot be interchanged with multiple or other observation optical sights.
[0304] In one embodiment, the present disclosure relates to a system that includes an observation optical sight and a laser rangefinder device, the observation optical sight having a body and a base, the body having a first optical system, the base being coupled to the body and having a second optical system, the second optical system being, for example, an integrated display system.
[0305] 1. Integrated display system
[0306] In one embodiment, the second housing includes an integrated display system. In another embodiment, the base includes an integrated display system. In yet another embodiment, a base having an integrated display system is coupled to the body of the sight. In yet another embodiment, the base is coupled to the bottom of the body of the sight.
[0307] In one embodiment, the base has an integrated display system that includes an active display, a condenser optic, and a reflective material including but not limited to a mirror. In one embodiment, the integrated display system has the following architecture: an active display, followed by a condenser optic, followed by a reflective material such as a mirror.
[0308] Figure 12 A top cross-sectional view of a base 220 coupled to the body of an observation optic is depicted. The base 220 includes an integrated display system having a microdisplay 1210, a condenser optic 1220, and a mirror 1230. In one embodiment, the mirror 1230 can be positioned at any suitable angle.
[0309] Figure 13 A side cross-sectional view of a base 220 having an integrated display system having a microdisplay 1210, a condenser optic 1220, and a mirror 1230 is depicted. The body 210 has a beam combiner 320 located above the mirror 1230.
[0310] Figure 14 A side cross-sectional view of a sight having a body 210 and a detachable base 220 is depicted. The base 220 includes a microdisplay 1210, a condenser optic 1220, and a mirror 1230. The mirror 1230 is positioned at approximately 45 degrees. The mirror body 210 has a beam combiner 320 located generally above the angled mirror 1230. The beam combiner 320 is generally located below the elevation adjustment knob 1410 of the mirror body 210. When the base 220 is coupled to the body 210 of the observation optic, the active display 1210 is located in the base on the eyepiece assembly side 1420.
[0311] As Figure 15As shown, the image generated from the microdisplay 1210 can be redirected from the display optical axis A to the viewing optical axis A, through the mirror 1230, to the beam combiner 320 in the body 210, to simultaneously superimpose or overlap the digital image onto the image of the scene observed by the observer through the optical sight in the first focal plane 1510. Since the beam combiner 320 is located before the first focal plane 1510 and the combined image is focused on the first focal plane, the displayed image and the observed image do not move relative to each other. This is a significant improvement compared to devices that inject the image into the second focal plane.
[0312] In one embodiment, as Figure 16 shown, when the base is coupled to the body of the sight, the active display 1210 is located in the portion of the base closest to the objective lens assembly 214 compared to the eyepiece assembly of the body of the sight. The body of the sight has an analog reticle 1610.
[0313] Figure 17 The sight 200 is depicted, which has: a body 210 having a beam combiner 320; and a base 220 coupled to the body and having an integrated display system. As Figure 17 shown, when the base is coupled to the body of the sight, the active display 1210 is located in the portion of the base closest to the eyepiece assembly compared to the objective lens assembly of the body of the sight. By superimposing the image from the integrated display system onto the first focal plane, the user can still use the traditional glass-etched reticle 1610 for calibration purposes.
[0314] In one embodiment, the integrated display system can direct the image generated from the active display along the display optical axis A. The generated image can be directed from the display optical axis A to a mirror in the base, to the beam combiner in the body of the sight, so as to simultaneously superimpose or overlap the generated image onto the image of the scene observed by the observer through the optical system of the body, where the combined image is injected or focused onto the first focal plane of the optical system of the body.
[0315] In one embodiment, the image generated from the active display in the base is focused on the first focal plane of the body of the sight, which allows the image generated by the display to remain aligned with externally mounted accessories.
[0316] In one embodiment, the image generated from the active display in the base is focused on the first focal plane of the body of the sight, and thus, the generated image does not depend on the movement of the erecting tube. The generated image is independent of the movement of the erecting tube.
[0317] In one embodiment, light from the active microdisplay is collected by a set of optical lenses. The light from the display is reflected to a beam combiner in the sight main body assembly and forms an image of the display that coincides with the first focal plane of the sight. This image of the display is combined with the image from the scene (target) and is perceived as being "under" the traditional wire or glass etched reticle. In one embodiment, the still used "traditional" reticle obscures both the image of the scene and the image of the display. If the brightness of the display is increased to a sufficient level, the image of the OLED display will saturate the image of the scene and will also appear to obscure the scene.
[0318] In yet another embodiment, the integrated display system in the base can direct the generated image along the display optical axis "B" onto the observation optical axis A in the body of the sight. A mirror or similar reflective material in the base can be used to redirect the image from the display optical axis B to the beam combiner in the body onto the observation optical axis A in the body, which allows the generated image to be superimposed or overlapped simultaneously onto the image of the scene that the observer observes through the optical sight in the body. The image generated from the active display in the base is directed towards the mirror, which reflects the image to the beam combiner.
[0319] In one embodiment, the display optical axis "B" and the observation optical axis "A" are substantially parallel, but other embodiments can be oriented differently as needed.
[0320] A. Active display
[0321] In one embodiment, the integrated display system has an active display. In one embodiment, the active display is controlled by a microcontroller or a computer. In one embodiment, the active display is controlled by a microcontroller with an integrated graphics controller to output a video signal to the display. In one embodiment, information can be sent wirelessly or via a physical connection through a cable port into the observation optical sight. In yet another embodiment, many input sources can be input into the microcontroller and displayed on the active display.
[0322] In one embodiment, the active display and the beam combiner are not in the same housing. In one embodiment, the active display and the beam combiner are located in separate housings.
[0323] In one embodiment, the active display can be a reflective, transmissive, or emissive microdisplay, including but not limited to microdisplays, transmissive active matrix LCD displays (AMLCDs), organic light emitting diode (OLED) displays, light emitting diode (LED) displays, electronic ink displays, plasma displays, segmented displays, electroluminescent displays, surface conduction electron emitter displays, quantum dot displays, etc.
[0324] In one embodiment, the LED array is a micropixelated LED array, and the LED elements are micropixelated LEDs (also referred to as microLEDs or μLEDs in the specification), which have a small pixel size typically less than 75 μm. In some embodiments, the LED elements may each have a pixel size ranging from about 8 μm to about 25 μm, and a pixel pitch ranging from about 10 μm to about 30 μm (in both the vertical and horizontal directions on the microLED array). In one embodiment, the microLED elements have a uniform pixel size of about 14 μm (e.g., all microLED elements have the same size within a small tolerance range), and are arranged as a microLED array with a uniform pixel pitch of about 25 μm. In some embodiments, the LED elements may each have a pixel size of 25 μm or less and a pixel pitch of about 30 μm or less.
[0325] In some embodiments, the microLEDs can be inorganic and based on gallium nitride light-emitting diodes (GaN LEDs). A microLED array (including multiple μLEDs arranged in a grid or other array) can provide a high-density, emissive microdisplay that is not based on an external switching or filtering system. In some embodiments, a GaN-based microLED array can be grown on, bonded to, or otherwise formed on a transparent sapphire substrate.
[0326] In one embodiment, the sapphire substrate is textured, etched, or otherwise patterned to increase the internal quantum efficiency and light extraction efficiency of the microLEDs (i.e., extract more light from the surface of the microLEDs). In other embodiments, silver nanoparticles can be deposited / dispersed on the patterned sapphire substrate before bonding the microLEDs to coat the substrate, thereby further improving the light efficiency and output power of the GaN-based microLEDs and microLED arrays.
[0327] In one embodiment, the active display can be monochromatic or can provide full color, and in some embodiments, can provide multiple colors. In other embodiments, other suitable designs or types of displays can be employed. The active display can be driven by electronic devices. In one embodiment, the electronic devices can provide the display function, or can receive these functions from another device in communication with it.
[0328] In one embodiment, an active display can be part of a backlight / display assembly, module, or device, having a backlight assembly that includes a backlighting or light source, device, apparatus, or component, such as an LED backlight for illuminating the active display with light. In some embodiments, the backlight source can be a large area LED and can include a first or integrated lens for collecting and directing the generated light to a second illumination or condenser lens, which is for collecting, concentrating, and directing the light along the display optical axis B onto the active display with good spatial and angular uniformity. The backlight assembly and the active display are capable of providing an image with a high enough luminance at low power so that it can be viewed as a very high luminance real-world view through an optical device.
[0329] The backlight color can be selected as any single color, or can be white to support a full-color microdisplay. Other backlight design elements can be included, such as other light sources, waveguides, diffusers, micro-optics, polarizers, birefringent components, optical coatings, and reflectors, for optimizing the performance of the backlight and being compatible with the overall size requirements of the active display as well as the luminance, power, and contrast requirements.
[0330] Figure 16 and 17 A representative example of an integrated display system in a base coupled to a body is depicted, showing a display, an optical system, and a mirror. The integrated system works with an optical system housed in the body of an observation optical mirror, which is depicted above the integrated display system.
[0331] Representative examples of microdisplays that can be used include, but are not limited to: Microoled, including MDP01 (series) DPYM, MDP02, and MDP05; Emagin such as SVGA, with microdisplays having pixel pitches of 9.9×9.9 microns and 7.8×7.8 microns; and Lightning Oled microdisplays, such as those produced by Kopin Corporation. Micro-LED displays can also be used, including but not limited to those produced by VueReal and Lumiode.
[0332] In one embodiment, the electronics working with the active display can include the capabilities of generating display symbols, formatting the output of the display, and including battery information, power regulation circuitry, a video interface, a serial interface, and control features. Other features for additional or different functions of a display overlay unit can be included. The electronics can provide the display function or can receive these functions from another device with which it communicates.
[0333] In one embodiment, an active display can generate images, including but not limited to text, alphanumeric, graphics, symbols, and / or video images, icons, etc., including active reticles, range measurements, and wind information, GPS and compass information, firearm tilt information, target detection, identification, and recognition (ID) information, and / or external sensor information (sensor video and / or graphics), or images for situational awareness, to be viewed through an eyepiece together with the image of the view seen through an optical sight. The direct vision optical device can include or hold an etched reticle and bore sighting and maintain high resolution.
[0334] In one embodiment, the use of an active display allows programmable electronic aiming points to be displayed at any position in the field of view. This position can be determined by the user (such as in the case of a rifle that fires supersonic and subsonic ammunition and thus has two different trajectories and "zeros"), or it can be calculated based on information received from a ballistic calculator. This will provide "drop compensation" aiming points for long-range shooting and can be updated at intervals between shots.
[0335] In one embodiment, the active display can be oriented to achieve maximum vertical compensation. In one embodiment, the active display is positioned with a height greater than its width.
[0336] In one embodiment, the orientation of the active display is as Figure 18 shown, which allows the maximum range of vertical adjustment 1810 of the active reticle within the sight. The maximized vertical adjustment is beneficial because it allows for ballistic compensation of the scene over longer ranges.
[0337] In one embodiment, the integrated display system further includes a processor in electronic communication with the active display.
[0338] In another embodiment, the integrated display system can include a memory, at least one sensor, and / or an electronic communication device in electronic communication with the processor.
[0339] Method of using ranging
[0340] In one embodiment, the active display can display range measurements obtained from a laser rangefinder. In one embodiment, the LRF can be coupled to the observation optical sight. In one embodiment, the LRF is directly coupled to the outer housing of the sight. In another embodiment, a portion of the LRF is directly coupled to the exterior of the housing of the sight.
[0341] In one embodiment, the LRF is indirectly coupled to the outer housing of the sight. In another embodiment, a portion of the LRF is indirectly coupled to the exterior of the housing of the sight.
[0342] In another embodiment, the LRF is not coupled to the sight, but communicates with the sight either hardwired or wirelessly.
[0343] In general operation, the LRF provides laser pulses that are projected into the scene via projection optics. The laser illuminates an object, and a portion of the laser is reflected back to the LRF. The portion of the reflected laser that returns to the device is captured by a receiving optical system and directed to a detector. The device includes a timer that starts when the laser pulse is emitted and stops when the returned laser is detected. The calculator section of the device uses the elapsed time from the emission of the laser pulse to the detection of the returned reflected laser to calculate the distance to the object.
[0344] In one embodiment, the distance calculation result is sent to an active display, and the generated image (distance measurement result or calculation result) is redirected from the display optical axis "B" to the observation optical axis A using a mirror and a beam combiner to simultaneously superimpose or overlap the image (distance measurement result or calculation result) onto the image of the scene observed by the observer through the observation optics.
[0345] Drag range bar
[0346] In another embodiment, the active display can generate a windage range. In one embodiment, the user can provide a series of wind values, and the software can generate windage data, such as windage range variance bars. In one embodiment, the windage data is sent to the active display, and the generated image (e.g., windage range variance bars) is redirected from the display optical axis "B" to the observation optical axis "A" using a mirror and a beam combiner to simultaneously superimpose or overlap the image (windage range variance bars) onto the image of the scene observed by the observer through the observation optics.
[0347] In one embodiment, the windage data includes the minimum wind hold point to the maximum wind hold point.
[0348] In one embodiment, the windage data is sent to the active display, and the active display can generate a digital reticle into the field of view when the appropriate wind is held.
[0349] Display color for psychological cues
[0350] In one embodiment, the active display can generate a color display to convey an additional level of information to the user in a format that is quickly understood. In one embodiment, the active display can generate a series of color-coded symbols to indicate ready to fire.
[0351] In one embodiment, an active display may generate a series of color-coded symbols to color-code objects in a target scene. In one embodiment, the active display may color-code friendly and enemy forces. In another embodiment, the active display may color-code targets of interest.
[0352] In one embodiment, the active display may produce a series of color-coded symbols to indicate the status of windage adjustment. In one embodiment, a red dot may indicate that the windage adjustment is not yet complete, while a green symbol may indicate that the windage adjustment is complete.
[0353] In another embodiment, the active display may produce color-coded reference points. In one embodiment, if proper adjustments have not been made, including but not limited to windage, distance, and elevation, the reference point will be red. In another embodiment, if some but not all of the firing adjustments have been completed, the reference point will be yellow. In yet another embodiment, if all necessary firing adjustments have been completed, the reference point will be green and the reference point is fully compensated.
[0354] In yet another embodiment, the blinking and steady states of the symbol may be utilized to convey similar status information regarding the adjustment of the reference point.
[0355] In yet another embodiment, the active display may generate text displayed in color to indicate status. In one embodiment, red text may indicate that input parameters have not been entered or calculated, and green text indicates parameters that have been entered or calculated.
[0356] Markings for impact zone in ranging
[0357] In one embodiment, the active display may produce circles, squares, or other shapes to allow the user to quickly enclose or circle the impact area of the projectile.
[0358] Maintain estimation and compensation
[0359] In another embodiment, the active display may generate reference points that compensate for a moving target based on user input for direction and rate of movement. For example, the user may input a movement rate of 5 miles per hour to the left. If the wind and the movement direction are the same, this will be added to the windage value, and if the wind and the movement direction are opposite, it will be subtracted from the windage value. Then, when the reference point and / or the windage value bar are drawn on the display, the reference point will include an appropriate hold amount to allow the user to place the reference point dot on the desired impact area and fire, rather than having to place the reference point in front of the moving target to compensate for the movement.
[0360] Team operations via camera and remote display manipulation
[0361] In one embodiment, an active display combined with a network interface allows for an additional level of enhanced operation and use. In one embodiment, reticle images of multiple shooters on a network can be observed. The reticle camera images of each shooter are displayed on more than one console, and network processing and interfaces enable group-level coordination, training, and cooperation, as opposed to what was previously used in individual scopes.
[0362] Training and instruction . In a training or instructional scenario, the coach can see how each shooter aligns his or her reticle with his or her respective target. By being able to actually see the reticle alignment, the coach or trainer can then provide instructions regarding adjustments and repositioning, such as by verbal instructions (e.g., via radio or in person).
[0363] In another embodiment, the coach's console can be equipped with a pointing device, such as a mouse or joystick, and control data is transmitted via the network from the console to the integrated display system of the rifle. The coach's mouse or joystick then controls an additional point or pointer in the display of each shooter's scope, which allows the coach to visually show the shooter which target to use, which range marker to use, and where to position the reticle relative to the target. In one embodiment, each shooter can be provided with his or her own coach's point, enabling the coach to provide personalized instruction to each shooter.
[0364] Shooting coordination . In another embodiment, the active display can be used for the coordination and execution of a multi-shooter firing team. In one embodiment, the team's commander operates the coach's console and uses the coach's point to help assign targets to each shooter, convey changes in reticle placement, etc.
[0365] Snapshot for remote review and approval . In another embodiment, the active display and network processing can allow a shooter equipped with a control device to take a "snapshot" of his or her reticle view. This snapshot of the user's reticle view can include an image of the target in question. When the commander or coach receives this image, the commander or coach reviews the image and approves or disapproves the shot. For example, in an instructional scenario, the user can take a snapshot of an animal that he or she believes to be a legal animal (age, species, gender, etc.). If the coach agrees, the coach can indicate so by positioning or moving the coach's point in the shooter's reticle.
[0366] Biometric classification of targets。In another embodiment, a snapshot of the reticle image is received by a biometric and / or classification process (such as a facial recognition system). The biometric and / or classification process can be on the firearm, such as integrated into the display control logic, or can be remote from the firearm and interconnected via a network. By sending the results via the network to the control logic and appropriately updating the display, the results of the recognition and / or classification process can be provided in the reticle.
[0367] Side - by - side image display 。In another embodiment, the image is downloaded via the network to an integrated display system and is displayed coincidently in the reticle together with the observed target image. The downloaded image can be used for the user currently observing the target to make a side-by-side comparison with an image or photograph of a previously captured target that is similar to the target the shooter is instructed or wishes to shoot. For example, during deer season, an image of a deer can be provided in the reticle for new shooters for reference, which can be compared in real time with the actual animal observed through the scope. In military or law enforcement applications, an image of the enemy or fugitive being sought can be displayed in the reticle, allowing a sniper to compare it in real time with the face of the person observed through the scope.
[0368] Representative example of an active display
[0369] a. 530 - 570nm
[0370] In one embodiment, the present disclosure relates to an integrated display system using a 530 - 570nm microdisplay.
[0371] Figure 19 An integrated display system having a 530nm - 570nm digital display 1910 is depicted.
[0372] Figure 20 is a schematic diagram of an exemplary image 2020 that can be displayed with a 530nm - 570nm digital display 1910. As Figure 20 shown, a glass-etched reticle 2010 can be used with the devices and systems disclosed herein. These images are merely examples and should not be construed as limiting the amount or type of information that can be displayed with an active display.
[0373] In another embodiment, due to the sensitivity of the human eye, the integration of a 530nm - 570nm digital display 1910 allows for relatively higher efficacy than any other color display. It allows for a smaller amount of power consumption compared to powering a red or blue display to the same photometric luminance.
[0374] In another embodiment, the integration of a 530nm - 570nm digital display 1910 provides the end user with a stronger ability to discern the digital overlay from the background created by ambient light in daylight sightlines.
[0375] b. AMOLED
[0376] In one embodiment, the present disclosure relates to an integrated display system including an AMOLED microdisplay.
[0377] Figure 21 An integrated display system with an AMOLED digital display 2110 is depicted.
[0378] Figure 22 is a schematic diagram of an exemplary image 2210 that can be displayed on the AMOLED digital display. As Figure 22 shown, the glass-etched reticule 2010 can be used with the devices and systems disclosed herein. These images are merely examples and should not be construed as limiting the amount or type of information that can be displayed on an active display.
[0379] In one embodiment, the image generated by the AMOLED 2110 is integrated / imaged / focused in a first focal plane. In one embodiment, the use of the AMOLED display 2110 allows for increased contrast and greater complexity in the data displayed into the sight.
[0380] In one embodiment, the integration of the AMOLED display 2110 allows for the selection of individual pixels to be illuminated, thus enabling the easy display of complex data configurations in the sight.
[0381] In another embodiment, the integration of the AMOLED display 2110 allows for a small and light package size within the sight, due to the reduced need for backlighting in the system.
[0382] In another embodiment, the integrated display system does not require a backlight display component.
[0383] In yet another embodiment, the integration of the AMOLED display 2110 allows for reduced power consumption, as the ability to optimize the power usage of individual pixels is now available.
[0384] In one embodiment, the integration of the AMOLED display 2110 gives a contrast that allows for a clear "heads-up" type display within the sight. The contrast allows each floating feature to be individually positioned and represented without low glow around the pixels.
[0385] B. Condensing lens system
[0386] In one embodiment, an integrated display system has an optical system based on using an optical lens as part of more than one lens unit, where the lens unit includes the lens itself and a lens unit body that mounts the lens. In one embodiment, the lens unit includes a precisely formed body that is generally cylindrical or disk-shaped. The body has a central hole for aligning the lens with the optical axis of a larger optical system. It can also be said that the unit body has its own alignment axis, which will ultimately align with the optical axis of the larger system when the lens unit is mounted in the larger system. Additionally, the lens unit serves as a "holder" for the lens and as a mechanism by which the lens can be mounted into and within a larger optical system, and the lens unit ultimately serves as a tool through which the lens can be manipulated and used for the purposes of the system.
[0387] In one embodiment, the integrated display system includes a condenser lens system, also referred to as a lens system. In one embodiment, the condenser lens system includes an inner lens unit and an outer lens unit.
[0388] Figure 23 is a representative example of a condenser lens system 2310 that has an inner lens unit 2315 and an outer lens unit 2320. In one embodiment, the outer lens unit 2320 contains at least one lens, and the inner lens unit 2315 contains at least one lens. In one embodiment, the inner lens unit 2315 rotates on the inner surface of the outer lens unit 2320. As Figure 23 shown, the active display 1210 is coupled to a flat machined surface on the back of the inner lens unit 2315. In one embodiment, the active display 1210 can be directly coupled to the inner lens unit 2315. In yet another embodiment, the active display 1210 can be indirectly coupled to the inner lens unit 2315.
[0389] One advantage of the condenser optical system disclosed herein is that the combination of the inner lens unit and the microdisplay mount provides a stable rotational mechanical axis for positioning the vertical axis of the microdisplay.
[0390] Figure 24 is a representative depiction of a base 220 coupled to the body of an observation optical mirror, where the base has a condenser optical system 2310 that is part of an integrated display system. In Figure 24 it, the body is depicted by a beam combiner 320 and an observation optical reticle 2420.
[0391] The outer lens unit 2320 is fixed in place relative to the observation optical system in the body while allowing the inner lens unit 2315 to float rotatably inside the outer lens unit 2320. By applying pressure to the surface 2410 of the inner lens unit 2315 that is below the rotational axis of the lens unit, the vertical axis of the active display 1210 can be aligned with the vertical axis of the reticle 1610 of the observation optical system.
[0392] Figure 25 is a representative depiction of one embodiment for aligning the tilt of the vertical axis of the active display with the vertical axis of the reticle. As Figure 25 shown, opposing fixing screws 2505 can bear against the surface of the inner lens unit 2315 that is below the rotational axis of the lens unit. The fixing screws 2505 can be used to align the vertical axis of the microdisplay 1210 with the vertical axis of the reticle in the optical system in the body of the observation optical mirror. By firmly tightening the fixing screws 2505 against the lower surface of the inner lens unit 2315, the rotation of the inner lens unit 2315 can be maintained, thereby rotationally locking the vertical axis of the microdisplay 1210 in place.
[0393] Figure 26 is a representative depiction of a rear cross-sectional view of the condenser lens system 2300 having a tilt adjustment mechanism for the microdisplay 1210 or the active display. When injecting the microdisplay into the optical system of the observation optical mirror by using a beam combiner or a waveguide, an additional compensation method is needed to eliminate the tilt error between the vertical axis of the reticle and the injected image of the vertical axis of the microdisplay. The fixing screws 2505 can bear against the surface of the inner lens unit 2315 that is below the rotational axis of the lens unit, thereby aligning the vertical axis of the microdisplay 1210 with the vertical axis of the reticle in the optical system in the body of the observation optical mirror.
[0394] Figure 27 is a representative depiction of a method and apparatus for eliminating the parallax between the microdisplay and the reticle in the optical system in the body of the observation optical mirror. The outer lens unit 2320 includes at least one lens on the Figure 27 right - hand side, and the inner lens unit 2315 includes at least one lens on the Figure 27 left - hand side. The inner lens unit 2315 slides along the optical axis on the inner surface of the outer lens unit 2320. The microdisplay 1210 is coupled to the inner lens unit 2315. A spring 2710 is installed between the outer lens unit 2320 and the inner lens unit 2315 to separate the two units without a compressive force.
[0395] Figure 28A is a representative depiction of a base having a condenser optical system 2300 coupled to the body of the observation optical mirror. In Figure 28AIn it, the main body is depicted by a beam combiner 320 and an observation optical reticle 2810.
[0396] The outer lens unit 2320 is fixed in place relative to the observation optical mirror and allows the inner lens unit 2315 to float inside the outer lens unit 2320. By using screws or wedges 2820 that apply force to the back of the inner lens unit / active display mount, the inner lens unit 2315 is forced forward, changing the axial position of the image such that the focal plane of the microdisplay image lies in the same plane as the observation optical reticle in the main body of the observation optical mirror. Thus, the parallax between the microdisplay and the reticle is eliminated.
[0397] The position of the inner lens unit is maintained in place by the action of a spring pressing outward on the screws or wedges. The parallax between the active display and the reticle can be eliminated without changing the amount of light collected from the active display or degrading the image quality of the system.
[0398] By using a spring between the inner lens unit and the outer lens unit and the force applied to the back of the inner lens unit / microdisplay, the maximum amount of light can be collected from the microdisplay, and a fast, simple, and accurate adjustment method is provided.
[0399] In one embodiment, the inner lens unit 2315 and the outer lens unit 2320 may include more than two lenses. In yet another embodiment, the lens system may include 3, 4, 5, 6, 7, 8, 9, 10, or more than 10 lenses. The lenses can be obtained from various commercial manufacturers, including but not limited to LaCroix Optics (www.lacroixoptics.com) and DiverseOptics (www.diverseoptics.com). In one embodiment, the inner lens unit and the outer lens unit include a condenser lens system.
[0400] In one embodiment, the five-lens system is composed of a five (5)-lens system. In another embodiment, the five-lens system includes 5 single lenses. In another embodiment, the five-lens system includes two doublets and one single lens. In yet another embodiment, the five-lens system includes 3 single lenses and 1 doublet. In one embodiment, at least one plastic aspheric surface is used as the first element.
[0401] In one embodiment, the lens system is a five-lens system having the following order: an aspheric single lens closest to the active display, followed by a single lens, then a doublet, and then the final single lens.
[0402] In one embodiment, the lens system is a five-lens system having the following order: an aspherical singlet lens closest to the active display, followed by a singlet lens, followed by a singlet lens, and then a doublet lens.
[0403] In one embodiment, the lens system is a five-lens system having the following configuration: lens 1 closest to the active display, with a diameter of 11 mm and a thickness of 9.3 mm; lens 2, with a diameter of 9 mm and a thickness of 1.9 mm; a doublet lens having one lens (lens 3) with a diameter of 13.5 mm and a thickness of 2.1 mm, and another lens (lens 4) with a diameter of 13.5 mm and a thickness of 4.1 mm; lens 5, with a diameter of 13.5 mm and a thickness of 3.3 mm.
[0404] In one embodiment, the gap between one lens and the next lens is in the range of about 1 mm to about 20 mm. In one embodiment, the gap between one lens and the subsequent lens is in the range of about 5 mm to about 20 mm. In one embodiment, the gap between one lens and the subsequent lens is in the range of about 10 mm to about 20 mm.
[0405] In one embodiment, the distance between the active display and the first lens is minimized so as to collect the maximum amount of light from the display. In one embodiment, the distance between the active display and the first lens is less than 2 mm. In another embodiment, the distance between the active display and the first lens is selected from the group consisting of less than 1.8 mm, less than 1.5 mm, less than 1.3 mm, less than 1.1 mm, less than 0.9 mm, less than 0.7 mm, less than 0.5 mm, and less than 0.3 mm.
[0406] In one embodiment, the five-lens system is housed in an inner lens unit and an outer lens unit. In one embodiment, the inner lens unit is constructed as follows: the aspherical lens is mounted into the inner lens unit from the opposite end where the display seat is located; then a spacer; next is lens 2, which can be a 9 mm singlet lens; then a retaining ring that fixes the two lenses in place.
[0407] In one embodiment, the outer lens unit is constructed as follows: lens 5 (which can be a 13.5 mm singlet lens) is inserted into the outer lens unit from the display end of the unit; then a spacer; then the doublet lens that can be lenses 3 and 4, and then a retaining ring.
[0408] Figure 28BIt is a representative depiction of a base with a condenser optical system or a condenser lens system. The inner lens unit 2315 is constructed by mounting the aspherical surface 2840 from the opposite end where the display base is located into the inner lens unit; followed by a spacer; and then the glass meniscus lens 2850. In one embodiment, the glass meniscus lens can be lens 2 as described above. The outer lens unit 2320 can be constructed by inserting the glass doublet lens 2860 and the glass singlet lens 2870.
[0409] In one embodiment, the condenser lens system includes a five-lens system, including 2840, 2850, 2860, and 2870, where 2840 is closest to the active display, and 2870 is the farthest from the active display. In one embodiment, the inner lens unit 2315 includes 2840 and 2850. In one embodiment, the outer lens unit 2320 includes 2860 and 2870.
[0410] In one embodiment, when the inner lens unit axially moves along the inner diameter of the outer lens unit, the spacing between lens 2 in the inner unit and lens 3 in the outer unit changes. This causes the focal plane of the image of the display to shift and is used to eliminate the parallax between the projected display image and the passive reticle in the body of the observation optical mirror.
[0411] In one embodiment, focusing the display image onto the first focal plane of the optical system in the body is achieved by changing the gap between lens 2 and lens 3 in the 5-lens system, which is accomplished by changing the position of the inner lens unit relative to the outer lens unit.
[0412] In one embodiment, the lens assembly can also be assembled together within a lens barrel, which is an integral mechanical structure housing a series of lenses. It is used to axially and radially position the lenses relative to each other and provides a means to interface the lens assembly with its associated system. The lens elements are radially positioned by the inner diameter or ID of the barrel wall. The outer diameter or OD of the ground lens elements is adapted to the ID of the barrel wall. The axial position of the lens elements is achieved by cutting the lens mounts during assembly. The lens elements can then be constrained to the mounts by epoxy resin, retaining rings, etc.
[0413] C. Reflective material
[0414] In one embodiment, the integrated display system includes a reflective material 1230. In one embodiment, the reflective material 1230 is a mirror. In one embodiment, the integrated display system includes more than one mirror. In one embodiment, the integrated display system includes two, three, four, or more mirrors.
[0415] In one embodiment, the mirror is positioned at an angle of 30° to 60°, or 30° to 55°, 30° to 50°, or 30° to 45°, or 30° to 40°, or 30° to 35° relative to the emitted light of the display.
[0416] In one embodiment, the mirror is positioned at an angle of 30° to 60°, or 35° to 60°, 40° to 60°, or 45° to 60°, or 50° to 60°, or 55° to 60° relative to the emitted light of the display.
[0417] In one embodiment, the mirror is positioned at an angle of at least 40°. In one embodiment, the mirror is positioned at an angle of 45° relative to the emitted light of the display.
[0418] In one embodiment, as Figure 29 shown, the tilt of the mirror 2910 along the vertical axis can be adjusted by using screws or similar mechanisms. By screwing the screw against the base or the back of the mirror 2910, the angle at which the image of the microdisplay is reflected into the beam combiner can be changed. This correspondingly changes the tilt of the focal plane at the reticle 2930 of the observation optical mirror in the optical system of the observation optical mirror body. Using this adjustment, the parallax error along the vertical axis between the microdisplay and the reticle can be eliminated.
[0419] In one embodiment, the mirror is fixed to the base with more than one screw. In one embodiment, the mirror is fixed to the base using a compound (such as epoxy resin, resin, or glue or a combination thereof).
[0420] In one embodiment, the position of the mirror relative to the beam combiner can be adjusted to eliminate any errors, including but not limited to parallax errors.
[0421] In one embodiment, the position of the mirror relative to the active display can be adjusted to eliminate any errors, including but not limited to parallax errors.
[0422] 2. Power system
[0423] In one embodiment, the base coupled to the body of the observation optical mirror has a power system. In another embodiment, the base of the observation optical mirror has a cavity. The battery cavity can be integrated into the base coupled to the body of the observation optical mirror.
[0424] Figure 30 is a representative schematic diagram of the base 220 having a battery compartment 3005, where the base 220 is coupled to the body 210 of the sight 3000. As Figure 30 and 31As shown, the battery cavity 3005 extends from each side of the base to enclose the battery, which includes but is not limited to CR123 batteries. Compared with smaller batteries or coin-type batteries, CR123 batteries have a higher power capacity and discharge.
[0425] In one embodiment, the battery cavity 3005 is integral with the base 220, so only a battery cover is needed to protect the battery from the environment. No additional sealing is required.
[0426] In one embodiment, compared with the eyepiece assembly, the battery cavity 3005 in the base 220 is closer to the objective lens assembly 3010 of the main body 210 of the observation optical mirror.
[0427] Figure 32 is a representative depiction of the battery compartment 3005 integrated into the base 220. In one embodiment, the cavity 3005 is designed to first insert the positive electrode side of the battery, and has a mechanical stop at the bottom of the battery cavity to prevent incorrect installation and operation of the battery.
[0428] In one embodiment, the integrated battery cavity 3005 can use the same gasket as the gasket of the base 220 for the main body 210 of the telescopic sight. This provides a more reliable seal and eliminates mechanical devices because a separate battery cavity is not required. Second, there is no mechanical device for fixing the battery cavity because it is integrated into the base. This reduces the need for any mechanical interface for fixing the battery compartment. Since no mechanical locking of the battery cavity is required, the integrated battery compartment reduces the failure points of traditional battery compartments.
[0429] The integrated battery compartment eliminates any obstacles that impede the user. The integrated battery compartment is located below the observation optical mirror and is not affected by any adjustments and knobs on the traditional observation optical mirror. The integrated battery cavity is a major advancement because it allows the necessary space to accommodate larger batteries.
[0430] In one embodiment, the observation optical mirror can be set in a way that minimizes battery consumption and maximizes battery life. For example, when the operator presses a button or switch, the observation optical mirror with a laser rangefinder is activated. A rangefinder indicator is displayed on the screen. When the observation optical mirror is zeroed, the output laser of the external rangefinder will coincide with the indicator through an initial calibration step. When the operator activates the external rangefinder, the information is sent wirelessly or via a communication port to the observation optical mirror, signaling the device that the information has been received and needs to be displayed.
[0431] If the observation optical mirror is turned on and no data is received from an external device, the observation optical mirror will power off after a user-set time. After the information received from the external device is displayed, a power-off timer starts, and if no further button presses are recorded, the device will be powered off.
[0432] If more information is received from an external device, the screen will clear the previous information, display the updated information, and start a power-down timer. This cycle can continue for the number of times selected by the operator.
[0433] During the time that information is displayed on the screen, a bevel indicator is shown on the screen. It is refreshed by an accelerometer communicating with the microcontroller at each time interval. When the microcontroller is in the sleep mode, observing the overall button on the optical sight will control the brightness of the LEDs illuminating the reticle etched on the glass. When the optical sight is operating, the control of these LEDs will be suspended and during the corresponding button press, the brightness of the screen will change.
[0434] 3. Picatinny Mount
[0435] In one embodiment, the present disclosure relates to an optical sight having a body and a base, the base having a battery compartment and a Picatinny mount that can be coupled to the battery compartment. In one embodiment, a detachable Picatinny mount is attached to a protruding battery compartment, where the battery compartment is incorporated into a base coupled to the body of the sight.
[0436] Figures 33 to 35 is a representative schematic view of a sight having a body 210 and a base 220 coupled to the body 210, where the base has a battery compartment 3005 that can be attached to a Picatinny mount 3305. In one embodiment, the Picatinny mount 3305 is aligned with the battery compartment 3005 and secured with a fastener.
[0437] By attaching the mount 3305 to the battery compartment 3005 of the base 220, it utilizes the material required to fabricate the cavity 3005 for the battery. This eliminates the need for any additional material for the base, making the optical sight lighter and less invasive.
[0438] In one embodiment, the mount is positioned towards the objective lens and parallax knob of the adjustment knob such that it does not interfere with the user's ability to adjust the sight. Additionally, the top ring is removable, allowing for easy attachment of accessory devices (such as a laser rangefinder). By utilizing the Picatinny mount disclosed herein, since the integrated base secures the sight, no additional structural support from the top of the ring is required.
[0439] In one embodiment, the mount incorporates a cantilever Picatinny rail that extends forward towards the objective lens of the sight. This allows a weapon-mounted laser rangefinder to be directly placed on the bell of the sight. This type of mount allows for reduced shift upon impact and increased accuracy of the ranging device. It reduces the likelihood of shift upon impact because there are fewer variables that can affect the ranging device's acquisition of the desired target.
[0440] 4. Data Port
[0441] In one embodiment, the present disclosure relates to an observation optical mirror having a body and a base, the base having an active microdisplay for generating an image and combining the generated image into a scene image in a first focal plane of the body of the observation optical mirror, wherein the base has an axially oriented data port for interfacing with an auxiliary device, the auxiliary device including but not limited to a remote switch and a laser rangefinder.
[0442] Figure 36 FIG. 8 is a representative schematic view of a sighting scope 3600 having a body 210 and a base 220, wherein the base 220 has an axially oriented data port 3605. In one embodiment, the observation optical mirror may have one axially oriented data port. In another embodiment, the observation optical mirror may have more than two axially oriented data ports.
[0443] By utilizing the axially oriented data port 3605, the top-down profile of the entire observation optical mirror is minimized, thereby improving the robustness of the mounting system and its connections.
[0444] 5. External Video Source
[0445] In one embodiment, the active display in the base can be used as an optical assembly or optical system for a clip-on device on the device, including but not limited to a thermal imaging system and a night vision system.
[0446] The thermal imaging system allows various waves of the electromagnetic spectrum to be imaged and transmitted to the user, which are generally not capturable by the human eye. Traditional thermal weapon sights consist of two systems paired together: an infrared optical system that observes the scene; and a visible wavelength optical system that includes a microdisplay and a lens to recreate the image in front of the sight. There are also instances of catalytic photon enhancement that create what we call a "night vision" system. However, clip-on devices are typically attached to a rifle rail in front of the body of the sight. This setup blocks all ambient light that is normally imaged by the sight and only allows the use of digital images. To switch back to traditional images, the user must remove the system from the rail. Since alignment settings are made each time the sight is changed, impact displacement may occur. These clip-on units also tend to be large due to the need for an eyepiece / imaging system behind the digital display in the unit. In traditional systems, any real-time video feed would be a completely digital image, including visible spectrum output.
[0447] Figure 37FIG. 0 is a representative schematic view of a sighting scope 3700 having a body 210 and a base 220, the base 220 having an active display 1210 and a condenser optic 1220, the condenser optic 1220 being usable as an optical system of a thermal imaging unit 3705. The active display 1210 uses a beam combiner to produce an image focused on a first focal plane of the body of the sighting scope to integrate the image into a conventional day optic. The integration of the digital display allows a user to superimpose a digital image onto the ambient day optic. With the digital display disclosed herein, there is no need to remove a clip-on unit from in front of the viewing optic in order to view the ambient day optic. Instead, the digital display can be turned on and off as needed.
[0448] The integration of the digital display allows for zero image shift when switching between day visible and digital optics. Since the system is fully integrated, there is no need to zero each time the digital optic is turned on. The system is in sync due to the alignment of the combined optical system.
[0449] In one embodiment, the integration of the digital display constitutes an optical train that is typically the rear half of a clip-on unit. Since there is already a microdisplay in the base of the viewing optic, the thermal sight only needs an infrared optic; the image generated by the thermal sensor can be transmitted to the active display already incorporated into the base of the viewing optic. By integrating the thermal or NV sight in this way, the thermal / NV device will be shorter and lighter than existing weapon sights on the market. This allows for a smaller and lighter system to be designed since half of the optical train is now directly integrated into the base coupled to the body of the viewing optic. The rear optical system or display does not need to be integrated into a clip-on unit that contains the sensing device.
[0450] In addition, if a thermal weapon sight is mounted to the side of the sighting scope such that the thermal optic does not block the sighting scope objective, then it will be possible to superimpose a thermal image above the visible image that the user will be viewing. This will be advantageous for being able to highlight humans, animals, or anything with a heat signature that stands out in a neutral daylight scenario.
[0451] In one embodiment, the integration of the digital display disclosed herein provides the advantage of feeding real-time video into the focal plane of the viewing optic without interrupting the day visible line of sight.
[0452] In one embodiment, the integration of the digital display allows for seamless integration of imaging overlays, such as a real-time thermal imaging view and a hyperspectral overlay system. The visible image is now analog rather than another digital display.
[0453] In one embodiment, the integration of the digital display disclosed herein provides the advantage of continuing the image feed even in the event of a sudden power drain on a digital system. The true analog image remains available, unlike conventional digital output systems.
[0454] In one embodiment, the integration of the digital display allows various types of imaging systems to be mounted separately from the front portion of the viewing optic. A thermal imaging system can be aligned with the bottom or side of the viewing optic and still feed the image directly onto the focal plane within the body of the viewing optic.
[0455] 6.EMI Vent Window
[0456] In one embodiment, the body, base, or both the body and base of the viewing optic can have a window sealed with a material transparent to electromagnetic waves used for wireless communication. Transparent materials include, but are not limited to, plastics, resins, or epoxy resins.
[0457] In one embodiment, the window allows EM waves to propagate from the communication device with reduced interaction with the metal body of the viewing optic. This increases the rate at which data can be transmitted. It also allows the wireless communication device to operate at a lower power level due to reduced signal loss.
[0458] III. Additional Sensors / Devices
[0459] In another embodiment, the present disclosure relates to a viewing optic having a body and a base, the base having an integrated display system and more than one sensor. In one embodiment, the sensors include, but are not limited to, global positioning system, accelerometer, magnetometer, MEMS rate sensor, tilt sensor, laser rangefinder.
[0460] A. Pointing Angle, Target Location, and Communication
[0461] In one embodiment, the viewing optic can have an inertial MEMS rate sensor to determine the pointing angle of the weapon in inertial space. Example products are the LCG-50 from Systron Donner and the SiRRS01 from Silicon Sensing. In another embodiment, an accelerometer can be incorporated into the embedded electronics to determine the absolute tilt angle of the viewing optic and track weapon acceleration due to general movement or firing events.
[0462] To support aiming, in various embodiments, the viewing optic can have a GPS and / or digital compass. In one embodiment, the GPS and / or digital compass can be integrated into the viewing optic, for example, as a board-level module. In another embodiment, the GPS and / or digital compass can be associated with a separate device that communicates with the viewing optic.
[0463] Some manufacturers offer customization of shelf modules for GPS and digital compass functionality, which have small form factors and low power consumption characteristics. These devices are designed to be integrated into embedded components. For example, Ocean Server Technology manufactures the OS4000-T compass with 0.5-degree accuracy, consuming less than 30 mA and less than 3 / 4″ square. An example of a GPS device is the DeLorme GPS2058-10 module, which is 16 mm × 16 mm, in a surface mount package, and provides 2-meter accuracy.
[0464] In one embodiment, an observation optical mirror can have a data interface that provides one or both of wired and wireless capabilities, which are designed to interface with systems such as BAE personal network nodes and emerging SRW radios. These interfaces provide various communication capabilities, such as range\sensors and other tactical data (e.g., anti-self-destruct detectors, environmental sensors, etc.). This unique functionality is used in various embodiments to obtain environmental information, target information, and situational awareness information and communicate it to interested parties. Generally, various embodiments are designed to enable a fighter aircraft to quickly acquire, reacquire, process data from various passive and active sources and otherwise integrate it into a ballistic firing solution, thereby enhancing the shooter's efficiency.
[0465] In another embodiment, the sensor provides information to an active display, enabling the generation of real-time position data of different targets onto a first focal plane of the body of the observation optical mirror. In another embodiment, the sensor is part of an external device that communicates with an integrated display system.
[0466] By using these sensors in the observation optical mirror, or on an external device rigidly connected to the observation optical mirror, or on a weapon on which the observation optical mirror is mounted, the exact position of the observation optical mirror and the exact direction in which the observation optical mirror is pointed can be obtained, and external targets can be calculated based on the observation optical mirror position and the calibrated direction.
[0467] When the user moves the observation optical mirror or when the target moves relative to the observation optical mirror, the position of the target will be continuously and real-time updated by sensors that communicate with the integrated display system, such that by observing through the observation optical mirror, the user will be able to see the position of the target relative to the location they are looking for.
[0468] This method has strong practicality in military applications, where personnel at different locations may attempt to communicate specific target locations to each other. For example, in close air support (CAS), a pilot may be flying an aircraft while a unit on the ground may rely on the aircraft to drop bombs on a target. Typically, it is difficult for the unit on the ground to convey the exact location of the target to the aircraft. The process of transmitting target information between the ground unit and the aircraft is commonly referred to as "talking to the target" and involves communicating what the unit or aircraft sees in its field of view, such as landmarks that may be seen near the target, etc.
[0469] This process usually takes a rather long time and may cause confusion because objects look different from the air than they do from the ground. It is crucial that each unit ensures they are looking at the same target because if the aircraft misidentifies the target, they may drop bombs on friendly units or non-combatants.
[0470] These problems are solved by allowing location and position sensors to communicate with the active reticle display of an integrated display system. The user of an observation optical sight can designate a target within their sight. The sight knows its GPS position, the exact direction it is pointing, and the distance to the target, and can calculate the precise GPS coordinates of the target. This information can be fed into a common system to which all friendly units are connected, such as Link 16. Now, the aircraft can simply look at the display on their aircraft, and once another unit has designated a new target, the new target will be displayed on their map.
[0471] This makes it faster to detect the target and easier to confirm that two units are looking at the same target. Accuracy is very important for determining the target location. Therefore, the image generated by the active display needs to be shown in the first focal plane of the observation optical sight body. If the generated image from the active display is placed in the second focal plane of the observation optical sight, the target position is only accurate when the reticle of the observation optical sight is in its "zeroed" position. If the user of the observation optical sight turns anything on their adjustment knob, such as for engaging a long-range target, all the target information in the display will be shifted by the amount turned in the adjustment knob and thus be inaccurate.
[0472] By using it together with the active display image injected into the first focal plane, the displayed data is agnostic to any adjustment made to the reticle position and compensates automatically. This means that the target data in the field of view is always accurate.
[0473] B. Environmental Sensors
[0474] In one embodiment, the observation optical sight may have more than one pressure, humidity, and / or temperature sensor, which is designed to collect and use environmental data for ballistic correction purposes. The sensors are in a micro configuration and are suitable for integration into the observation optical sight. Intersema's MS5540 is an example of a micro, low-power, waterproof, barometric pressure sensor. The component measures 6.2 × 6.4 mm in size.
[0475] In one embodiment, the sensor may be coupled to the main body of the observation optical sight or the base of the observation optical sight.
[0476] C. Uphill and downhill
[0477] In one embodiment, the observation optical sight may have a z-axis accelerometer, which can be used to measure the tilt angle of the sight relative to the vertical. At the time of target selection, this tilt angle can be integrated into the ballistic solution. Once the target is selected, the system is able to automatically integrate the actual uphill or downhill into the ballistic solution and display the solution on the first focal plane of the observation optical sight, so that the digital reticle or correction calibration points are correctly displayed. This can provide a very fast and effective aiming means in long-range uphill or downhill strikes.
[0478] IV. Observation optical sight with a display system and a laser rangefinder
[0479] In one embodiment, the present disclosure relates to an observation optical sight and a laser rangefinder. The observation optical sight has a main body and a base with an integrated display system. In one embodiment, the laser rangefinder is coupled to the observation optical sight. In another embodiment, the laser rangefinder is independent of the observation optical sight and communicates with the observation optical sight wirelessly or via a cable.
[0480] In one embodiment, the laser rangefinder is coupled to the observation optical sight via a mounting rail, and the mounting rail is attached to the base through the battery compartment.
[0481] In one embodiment, the laser rangefinder can be used to determine the distance to a target. In various embodiments, the laser is transmitted in the near IR for concealment. A typical wavelength for a laser rangefinder device operating in the near infrared (NIR) is 905 nm.
[0482] In one embodiment, specific laser power and spectral characteristics are selected to meet the distance and eye safety requirements of the observation optical sight. The rangefinder has sufficient power to produce accurate measurement results, such as 1500 meters, 2500 meters, or any effective distance related to the firearm or weapon intended to be used with the observation optical sight. For rangefinder operation, in some embodiments, a single-button control is dedicated to making or performing rangefinder measurements.
[0483] In one embodiment, the distance to a target can be transmitted to an active display that generates an image of the distance to the target and superimposes the distance to the target onto a first focal plane of an observation optical sight when observing a target scene.
[0484] In one embodiment, the observation optical sight has a computing device with ballistic calculator capabilities. In one embodiment, the body of the observation optical sight has a computing device with ballistic calculator capabilities.
[0485] In one embodiment, a laser rangefinder can be used to measure the target distance, calculate the projectile trajectory, and communicate the corrected aiming point to an active display in an integrated display system. The active display then superimposes an image of the corrected aiming point onto the first focal plane of the observation optical sight, which has a reticle attached to a movable erecting lens system.
[0486] Importantly, because the image generated by the active display is combined with the image from the target in front of the first focal plane and then focused onto the first focal plane, the target image and the display image never move relative to each other. Thus, any calibration reference created by the digital display will always be accurate regardless of how the movable erecting system is adjusted.
[0487] When an external laser rangefinder feeds distance information to the sight, a calibration reference or laser indicator needs to be created by the digital display so that the user knows which location in the LRF sight field of view, so that the correct target can be accurately hit with the laser. The digital display image and the target image of the objective lens system in the body of the sight do not move relative to each other. Thus, regardless of how the adjustment knob is adjusted to move the movable erecting lens system, the digital laser indicator will accurately show the user the correct position of the LRF laser aiming point.
[0488] On the other hand, if the digital display image is integrated into the optical system anywhere behind the first focal plane, then when the adjustment knob is adjusted and the erecting lens system is moved / tilted, the image of the digital display will move relative to the target image, and the digital LRF indicator will move relative to the actual laser aiming point. If the user turns any elevation or windage adjustment to the adjustment knob and forgets to turn back to the original position set by the adjustment knob when aligning the digital reticle with the actual laser aiming point, it may result in an incorrect distance measurement.
[0489] In addition, when zeroing a traditional sight on a rifle, the user typically selects a "zero" distance, usually 100 yards, for aligning the reticle of the sight with the point of impact of the rifle projectile. This is typically accomplished by adjusting the adjustment knobs of the sight and thus adjusting the tilt angle of the erect image lens system to align the reticle with the point of impact of the projectile. After setting the initial "zero" of the sight, the adjustment knobs allow the user to further adjust the position of the sight reticle to compensate for targets at different distances or to compensate for varying wind drift variables that affect the position at which the point of impact of the projectile may vary from the initial "zero" position.
[0490] If a digital display is integrated into the sight system behind the first focal plane, then the correction factor for the ballistic calculation's reference point may be incorrect if the user has made any adjustments to the adjustment knobs from the initial "zero". For example, if the ballistic calculator determines that a 10 milliradian elevation adjustment is required for correction to hit the target, the digital display places the reference point 10 milliradians below the center of the crosshairs. However, if the user has dialed 5 milliradians on the elevation adjustment knob from the initial "zero" position, the digital reference point will actually be aimed 15 milliradians below the initial "zero".
[0491] By injecting the digital display into the first focal plane of the optical system of the sight body, it allows the digital display to be completely unaffected by any changes in the adjustment knob adjustments or the position of the erect image system. This means that in the above example, the digital reference point will actually only appear 5 milliradians below the center of the reticle for a total of exactly 10 milliradians of ballistic drop (the user had previously dialed 5 milliradians into the elevation adjustment knob from the initial "zero" position). In short, injecting the digital display image into the first focal plane of the body's optical system makes the digital display image completely unaware of any changes in the adjustment knob position and thus completely unaware of the movement / tilt of the erect image lens system, which provides the required accuracy.
[0492] In one embodiment, the laser rangefinder capability provides a dynamically defined ballistic solution based on the acquired data. When processing the tracer round trajectory to determine the optimal point along the measured trajectory path for determining the ballistic correction for the next shot, the on-board computer can use the distance to the target.
[0493] In one embodiment, the laser rangefinder is integrated into the sight and has a dedicated output laser transmitting port. In one embodiment, the optical path of the dedicated laser axis is located in the corner of the housing so that it is not obstructed by the main objective lens. The detection path for the incident reflected laser signal passes through the main objective lens of the sight, where a near-IR beam splitter directs the light to the light detector. This arrangement takes advantage of the relatively large aperture of the main objective lens to increase the signal-to-noise ratio of the measurement result.

The observation optical scope 3800 may have two auxiliary ports 3805 for communicating with an external source. The observation optical scope 3800 may have a Picatinny mount 3305, which is coupled to the outside of a battery cover for a battery cavity 3005 in the base 3820.

In some embodiments, the observation optical scope may have an auxiliary port 4735.
[0497] V. Other Embodiments
[0498] 1. Digital Zeroing
[0499] In one embodiment, the present disclosure relates to a method for alignment and zeroing purposes using a digital reticle. In one embodiment, an observation optical scope has a physical reticle and a digital reticle, where the physical reticle is connected to an erect image system. The user moves the reticle and the erect image system using adjustment knobs to "zero" the physical reticle such that the center of the reticle coincides with the point of impact of the bullet.
[0500] After the physical reticle is zeroed, the digital reticle must also be zeroed. Since the digital reticle is formed by an active or digital display fixed in place, the only way to zero or align the digital reticle is using digital methods. The user can move the position of the digital reticle such that the center of the digital reticle coincides with the center of the physical reticle.
[0501] In another embodiment, digital zeroing can also be used with a laser indicator. When used in conjunction with an external laser rangefinder, the viewing optic laser indicator must be aligned with the direction in which the laser rangefinder is pointed. Most external laser rangefinders have both visible and infrared lasers. The infrared laser is the laser that actually measures distance. The visible laser can be turned on and off and is aligned with the aiming of the infrared laser. The visible laser allows the user to see where the laser is aimed. Once the visible laser is turned on, the user can digitally adjust the laser indicator to coincide with the calibrated point of the visible laser. The visible laser can then be turned off, and the user can use the laser indicator in the viewing optic display to ensure accurate calibration of the laser rangefinder.
[0502] 2. Holographic waveguide
[0503] In one embodiment, the present disclosure relates to a viewing optic having: a body having a first optical system; and a base having an active display and a holographic waveguide. In one embodiment, the integration of the holographic waveguide reduces the package size and weight of traditional beam combining systems. The integration of the holographic waveguide can increase the overall transmission brightness ratio such that a greater percentage of the light from each optical system reaches the end user.
[0504] Figure 49 is a representative depiction of a viewing optic 4900 having: an optical system in a body 4910; and a base 49 having an active display 1210; and a holographic waveguide system 4925. The holographic waveguide system 4925 spans the body 4910 and the base 4920. The digital or active display 1210 generates an image to a collimating optic 4930 which sends the image into an incoming holographic waveguide 4926. The image exits the waveguide via an output hologram 4927 and the image is injected into a first focal plane 4930 of an optical system 4940.
[0505] In one embodiment, the integration of the holographic waveguide reduces the need for specialized coatings fabricated for beam combiners. Additionally, the integration of the holographic waveguide interrupts the need for a mirror system, reducing the need for complex mechanical alignment systems.
[0506] The integration of the holographic waveguide allows for the creation of replicas of complex optical systems required for imaging the display, eliminating the need to place complex systems into each system.
[0507] The integration of the holographic waveguide allows for the use of LCOS, LCD, and OLED systems to display information within the optical system. The nature of the system allows for various types of illumination systems to be combined with the different types of displays used within the system.
[0508] The use of a holographic waveguide allows for the implementation of a reticle with non-static illumination. The reticle can be changed when the image on the screen changes. The holographic waveguide allows for a daylight-bright reticle system without the need for traditional illumination methods.
[0509] The integration of a holographic waveguide creates the ability to create a non-static holographic sight. The output-coupling hologram can transmit light defined by the main optical system, thus allowing for a change in the aiming picture of the holographic sight.
[0510] The integration of a holographic waveguide can be used with any monochromatic or polychromatic light source. The use of a complex multiplexed Bragg grating allows for the integration of a polychromatic illumination system.
[0511] 3. Tracking Bullet Trajectory
[0512] One difficulty associated with long-range strikes is the ability to determine the accuracy of an initial shot such that timely corrections can be made to improve the accuracy of the next shot. Traditional techniques for determining the point of impact of a projectile are to attempt to detect the bullet trace and / or the actual splash point of the bullet. In many long-range strikes, this can be difficult. In the case of a sniper team, subsequent shots also require feedback from an observer to feed relevant data back to the shooter. Using only verbal communication can take several seconds.
[0513] In one embodiment, an observation optical mirror may have an imaging sensor adapted to detect image frames related to the bullet flight path and transmit the image frames to a computing device, which can then calculate the bullet trajectory based on the image frames.
[0514] In one embodiment, an observation optical mirror having a body and a base (the base having an integrated display system) can allow for the detection of tracer bullets through on-board image processing capabilities, thereby determining the trajectory of the bullet before it impacts the target area. In one embodiment, this data can be sent back to a ballistic computer, which can quickly and effectively provide a follow-up shot solution for a second round, which can be transmitted to an active display and the corrected aiming point superimposed on the first focal plane of the body of the observation optical mirror.
[0515] Automating the feedback loop for trajectory and splash point detection through a computer, combining it with an active display, and superimposing an electronic aiming point correction on the first focal plane advantageously reduces the total time required for an accurate second shot. This time reduction can be a key point in the strike process. After the first shot, the opportunity window for a second shot can quickly narrow, especially if the delay exceeds the time point when the sonic boom of the initial shot reaches the predetermined target.
[0516] Environmental conditions and windage drift can have a significant impact on the ballistic trajectory of a projectile over long distances. For example, an M193 bullet can drift approximately 4 feet at 500 yards in a moderate 10 mile per hour crosswind. Since the velocity of the bullet decreases as the flight distance and total flight time increase, the windage effect becomes more exaggerated at greater distances.
[0517] A variety of tracer options are provided. Traditionally, shooters have used standard tracers to observe the trajectory of the bullet's flight path. Tracers can emit light in the visible or IR spectrum depending on the composition of the tracer material. The latter is effective when the shooter is using night vision equipment. Additionally, some tracers can first glow dimly and then brighten as the projectile travels downrange. A fuse element can control when the tracer ignites after the projectile is launched, thus causing a delay in igniting the tracer material until the bullet is fully downrange. The fuse delay reduces the risk of the tracer exposing the shooter's firing position.
[0518] In one embodiment, an observation optic with an integrated display system can use a tracer to detect, determine, and / or display the trajectory of a bullet before it impacts the target area. In one embodiment, a covert tracer with a long delay fuse and emitting in the near IR region (700nm to 1000nm) of the electromagnetic spectrum can be used. Light emitted in the near IR region is invisible to the human eye but can be detected by an imaging sensor using conventional glass optics. This type of tracer can be particularly effective in maintaining the shooter's concealment during sniper operations while providing an important automatic bullet tracking capability to accurately determine the next shot correction requirements. Accordingly, various embodiments are adapted to work with more than one type of tracer to achieve the functions described herein.
[0519] Since the imaging sensor in daylight embodiments is also sensitive to visible light, standard daylight tracers can also be used for bullet tracking. In the case of both visible light and near IR, the tracer can utilize a long delay fuse to increase concealment since the system only needs to detect the bullet's flight at the last moment before impact.
[0520] In one embodiment, a camera associated with the observation optic can record the trajectory of the bullet and use a sensor suite embedded in the observation optic that can calculate the exact geolocation trajectory of the bullet as well as the bullet's point of impact.
[0521] In another embodiment, the observation optic can also use a stabilized camera to compensate for recoil from the firearm. The observation optic will precisely track the movement of the stabilized camera and compensate for that movement to accurately calculate the geolocation trajectory of the bullet. This embodiment will allow the shooter to track their own trajectory and more accurately compensate for any misses.
[0522] In two embodiments, the geographical location trajectory of the bullet can then be shared with other users to display the trajectory in their field of view, and these other users can also actively display it in the devices they are using (such as another sight, projectile observation scope, or goggles using a microdisplay or holographic technology).
[0523] In one embodiment, tracking of the bullet trajectory incorporates capturing video frame images of a glowing tracer bullet in flight. The spatial position of the bullet in the selected image frames is extracted through image processing techniques and then correlated with data from other video frames to establish the bullet's trajectory.
[0524] Image frames are selected for processing based on their correlation with the firing event. When a projectile is launched from a weapon, the muzzle exit time is immediately determined by processing accelerometer data obtained from an on-board weapon axis accelerometer included in various embodiments. A correlation window starting from the muzzle exit time is then initiated, and in various embodiments, video images are processed frame by frame to identify a small cluster of pixels associated with the tracer bullet at a specific X-Y position in space. The frame images can be taken with an exposure time optimized to capture the bullet as it traverses a small number of individual pixels in the X-Y frame. Since the camera's frame rate and the muzzle exit time are known, the distance of the bullet from the weapon in each frame can be established using the known flight characteristics of the bullet. This data is contained in on-board tables associated with each weapon and its related projectile, or alternatively received from a tactical network communicating with the weapon sight.
[0525] If the absolute distance to the target is known from laser rangefinder measurements, the position of the projectile at the target distance can be calculated by determining the point in the trajectory corresponding to the target distance. The elegance of this technique is that the measurement is done using in-flight data and does not rely on a bullet impact with a physical surface. The calculated position will correspond to the angle of elevation and azimuth relative to the weapon's position and can be used to determine the ballistic aiming corrections required to improve accuracy. As part of the calculation of the next shot ballistic correction, various embodiments use inertial pointing angle data to calculate a relative reference point between the inertial pointing angle of the gun at muzzle exit and the pointing angle at splash. This allows the calculation to account for any angular movement of the gun that occurs during the bullet's flight time to the target distance.
[0526] 4. Other Configurations
[0527] Figure 50Depicts an alternative embodiment of the sighting scope 5000, which has a scope body 5005 and a compartment or notch 5010 on top of the scope body 5005. The compartment 5010 has an integrated display system, which includes an active display 5015 and a condenser optic 5020. The integrated display system is oriented such that the display 5015 and the condenser optic 5020 are parallel to the beam combiner 5025. In this embodiment, no reflective surfaces such as mirrors are required.
[0528] Figure 51 Depicts an alternative embodiment of the viewing optic 5000, which has a scope body 5005 and a compartment or notch 5010 on top of the scope body 5005. The compartment 5010 has an integrated display system, which includes an active display 5105, a condenser optic 5110, and a mirror 5115. The integrated display system is oriented such that the display 5115 and the condenser optic 5110 are perpendicular to the beam combiner 5025. In Figure 51 it, the active display 5105 is closer to the eyepiece system compared to the objective system of the viewing optic.
[0529] Figure 52 Depicts an alternative embodiment of the viewing optic 5000, which has a scope body 5005 and a compartment or notch 5010 on top of the scope body 5005. The compartment 5010 has an integrated display system, which includes an active display 5105, a condenser optic 5110, and a mirror 5115. The integrated display system is oriented such that the display 5105 and the condenser optic 5110 are perpendicular to the beam combiner 5025. In Figure 52 it, the active display 5105 is closer to the objective system compared to the eyepiece system of the viewing optic.
[0530] The image generated from the active display 5105 can be directed to the mirror 5115 and combined with the image of the scene observed by the observer through the viewing optic using the beam combiner 5025 in the scope body 5005, so that the generated image and the observed image are simultaneously superimposed or overlapped, where the combined image is injected into the first focal plane. Since the beam combiner 5025 is located before the first focal plane and the combined image is focused on the first focal plane, the displayed image and the observed image do not move relative to each other. This is a significant improvement compared to devices that inject the image into the second focal plane.
[0531] In yet another alternative embodiment, the viewing optic has a scope body and a separable base, and the base has an active display and a condenser optic, and the active display and the condenser optic are parallel to the beam combiner. In this embodiment, no reflective surfaces such as mirrors are required. The base is coupled to the bottom of the body of the viewing optic.
[0532] The image generated from the microdisplay can be combined with the scene image observed by the observer through the optical sight with the help of a beam combiner within the sight body, so as to simultaneously superimpose or overlap the generated image and the observed image, wherein the combined image is injected into the first focal plane. Since the beam combiner is located in front of the first focal plane and the combined image is focused on the first focal plane, the displayed image and the observed image do not move relative to each other. This is a significant improvement compared to the device that injects the image into the second focal plane.
[0533] The optical sights and methods disclosed herein can be displays or observation devices, apparatuses, sights or aiming scopes, which can be used on, or as part of, or as an additional accessory to weapons, guns, rifles, laser target locators, rangefinders. Embodiments can be mounted on weapons or devices, or can be handheld or helmet-mounted.
[0534] V. Observation Optical Sight with Advanced Reticle Function
[0535] A. Active Display Mode Based on Magnification Setting
[0536] In one embodiment, the present disclosure relates to an observation optical sight having a body and a base with an integrated display system, wherein the active display of the integrated display system generates a plurality of reticle patterns, and the plurality of reticle patterns are projected into the first focal plane of the field of view.
[0537] In one embodiment, the present disclosure relates to an observation optical sight having a body and a base with an integrated display system, wherein the active display of the integrated display system generates a reticle pattern based on the magnification level.
[0538] In one embodiment, the present disclosure relates to an observation optical sight having a body and a base with an integrated display system, the body having one or more sensors that can track or monitor the magnification level of the optical sight, wherein the active display of the integrated display system generates a reticle pattern based on the magnification level. Depending on the magnification level, the active display system can generate different reticle patterns optimized for different optical magnification levels. In one embodiment, the active display of the integrated display system can automatically switch between reticle patterns based on the magnification level.
[0539] In one embodiment, an observation optical sight with an integrated display system can project digital features or aiming points optimized for the specific magnification setting used.
[0540] In one embodiment, the body of the observation optical mirror has a sensor that is associated with the magnification adjustment mechanism of the aiming device to generate a signal indicating the adjustment of the optical magnification of the observation optical mirror. The observation optical mirror further includes an electronic controller that communicates with the sensor and the active display of the integrated display system. The electronic controller, in response to the signal generated by the sensor, communicates with the active display to generate a reticle pattern that can be observed through the eyepiece superimposed on the image of a distant object in its field of view.
[0541] In some embodiments, the electronic controller and the active display are configured to generate a first reticle pattern, such as a close-range reticle pattern, in response to a signal indicating a first magnification setting; and, in response to a signal indicating a second magnification setting greater than the first magnification setting, the electronic controller and the active display can generate a second reticle pattern different from the first reticle pattern. For example, the second reticle pattern can be a long-range reticle pattern such as a sniper reticle.
[0542] In some embodiments, the sensor can include a combination of electromechanical or optical digital encoders (which can be rotary or linear), potentiometers, one or more magnets and one or more Hall effect sensors, or other suitable devices operable to sense the position or movement of the magnification adjustment mechanism and generate a corresponding electrical signal. In one embodiment, the sensor is described in Figure 69 and Figure 70 .
[0543] In one embodiment, the active display is not in the body of the observation optical mirror.
[0544] In one embodiment, one or more reticle patterns can be selected from including but not limited to 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, and greater than 20. In one embodiment, an observation optical mirror with an integrated display system can select between at least 10, or at least 20, or at least 30, or at least 40, or at least 50 reticle patterns.
[0545] In one embodiment, the active display of the integrated display system projects the reticle pattern into the first focal plane of the field of view based on a specific magnification setting. When changing the magnification setting, the reticle pattern generated from the active display is switched so that the aiming point is immediately useful to the operator. The switching of the reticle can be based on the magnification setting.
[0546] By way of example and not limitation, at a 1X magnification setting, the active display can generate a small center point projected onto the first focal plane. When the magnification is changed to 8X, the active display generates a reticle pattern with long-range retention at the point projected onto the first focal plane. The sensor determines the change in magnification, which is communicated to the controller that changes the reticule pattern of the active display.
[0547] In one embodiment, an observation optical scope with an integrated display system projects information and aiming points that are intended to assist an operator in engaging targets at short and long ranges. In one embodiment, multiple "pages" of information or reticule patterns can be designed and loaded into the system, and different pages can be displayed depending on the magnification setting.
[0548] In one embodiment, the reticule pattern from the active display is projected onto an etched reticule on the first focal plane. In the event of a system failure, projecting a digital reticule onto the etched or fixed reticule provides the necessary protection.
[0549] Figure 53 is a representative depiction of a close combat reticule 5300 at 1X magnification. The thick arcuate line 5305, the main horizontal line 5307, the main vertical line 5309, the numbers and the arrows are components of the etched reticule. The center point 5310 is generated from the active display of the integrated display system. This reticule is used for close combat. The center point represents a quick target acquisition aiming point.
[0550] Figure 54 is Figure 53 a schematic view of the reticule, but the magnification setting of the observation optical scope is set to 8X. It can be seen that the center point 5310 projected from the active display becomes significantly larger at 8X magnification.
[0551] Figure 55 is a representative description of a reticule pattern 5500 that provides useful information when the observation optical scope is set to a magnification setting of 8X. The thick arcuate line 5502, the main horizontal line 5504, the main vertical line 5506, the numbers and the arrows represent the etched reticule. The center aiming point 5510, six ballistic compensated windage points 5520, and the square 5530 in the upper left (representing a rangefinder indicator showing the assumed distance to the target) are components generated by the active display.
[0552] Figure 56 is a representative depiction of the reticule pattern 5500 at a low magnification setting.
[0553] Reference Figures 53 to 56, when the optical magnification is set to 1X, the reticle pattern 5300 includes etched reticle features 5305, 5307, and 5309, and a first set of multiple marks 5310 (e.g., circles and / or aiming points) generated by the active display and projected onto the first focal plane reticle. Preferably, for example Figure 53 As shown, the reticle pattern 5300 formed at least in part by the first set of marks 5310 is a close quarters battle (CQB) reticle with minimal marks to provide a less cluttered visible area.
[0554] When the optical magnification setting is increased, the electronic controller and the active display (responsive to signals received from sensors, including but not limited to Figure 69 and Figure 70 the sensors described in) utilize a second set of multiple marks to replace / change / alter the first reticle pattern, which forms (at least in part) a second reticle pattern 5500 that is different from the first reticle pattern 5300 and generally includes at least some different functions.
[0555] For example, the second reticle pattern may include different aiming features and additional marks, such as those related to estimating distance, calculating windage, and elevation adjustments, or other suitable marks commonly used in ranging reticles, as Figure 55 shown.
[0556] Thus, it can be seen that creating multiple "page" features and reticle patterns for the active display, storing them in a memory system, and automatically switching between reticle patterns as the operator changes the magnification setting on the observation optic would be very useful.
[0557] B. Active BDC reticle
[0558] The ballistic drop compensation (BDC) reticle is designed to have hash marks on the vertical reticle portion located below the horizontal crosshair. These hash marks are designed to attempt to closely match a specific or specific group of ballistic profiles at a specific distance.
[0559] However, the current BDC reticle design is a fixed design. This is because the reticle is made of wire, metal, or etched on glass. Once the reticle is manufactured and installed in the scope, the reticle must be removed and a new one installed to make a change, which can only be achieved in practice by returning the scope to the manufacturer.
[0560] In one embodiment, the present disclosure relates to an observation optical mirror having a body and a base, the body having an optical system and the base having an integrated display system having an active display that can generate a BDC reticle that can be manually changed by a user at any time or even automatically changed in real time by the software and sensors of the observation optical mirror.
[0561] To generate the BDC reticle for the observation optical mirror disclosed herein, the sight can be programmed for the specific ballistic profile of the rifle and the cartridge to be fired. Second, the observation optical mirror has sensors (such as temperature, pressure, humidity, tilt angle, inclination angle) as described above, which can help to update the BDC reticle in real time so as to be as accurate as possible under all conditions. This enables the BDC reticle to be customized specifically for each rifle and specific shooting conditions.
[0562] The BDC reticle generated in real time by the active display enables the shooter to have an accurate system that can shoot accurately and quickly at various distances.
[0563] As Figure 57 shown, the reticle 5700 has standard etched and filled portions, which include a main horizontal line 5702, a main vertical line 5704, and numerical markings and hash marks along the main vertical crosshair. The reticle 5700 also has patterns and markings generated by the active display and projected onto the first focal plane reticle. The active display markings in the form of the BDC reticle include numerical markings 5710 (100 - 900 on the vertical axis in quadrants 3 and 4). Since this part is projected from a digital display, it can be updated in real time.
[0564] In addition to the active BDC reticle, sometimes the user / shooter may find themselves in a position to provide cover for other individuals in an area where the target may appear quickly and at different distances on its own. An example could be a sniper on top of a building overlooking an alley or a road crossing a street or doorway. The active display can be used in combination with various sensors (such as compass, tilt angle, inclination angle, GPS, etc.) embedded in the sight to be able to accurately determine the pointing direction of the sight.
[0565] Using an observation optical scope with environmental sensors, an integrated display system with an active display for generating a BDC reticle and projecting it onto a first focal plane, and a rangefinder, the user will be able to range known landmarks such as doors, windows, cars, etc., and place a distance marker on these landmarks using a controller and the active display. These distance markers are projected into the first focal plane and are visible through the observation optical scope. The environmental sensors allow the user to move the observation optical scope to view other targets, but the distance markers will remain on the targets.
[0566] Figure 58 It is a representative image of the BDC reticle generated by the active display and projected onto the first focal plane reticle, with the distances to potential targets marked. An observation optical scope having a body and a base, the body having environmental sensors and the base having an integrated display system with an active display for generating a BDC reticle, the observation optical scope will allow the user to mark multiple targets in one or more areas with distance indication markers on the target markers. Then, if a target presents itself near a target marker, the user will be able to quickly identify the distance to the target without having to range the target. Then, the user can use the active BDC reticle to quickly fix on the correct position to engage the target.
[0567] C. Reticle for compensating gun tilt
[0568] In a traditional rifle scope, when shooting at long distances, the firearm and the scope must be horizontal during shooting. When the bullet travels a long distance, the bullet is affected by gravity to a certain extent, and the shooter must take this into account. Gravity pulls the bullet towards the ground in a consistent direction, creating a "bullet drop". The shooter compensates for this bullet drop by aiming the bullet higher than the target so that when the bullet reaches the target, it has dropped to the appropriate height to hit the target.
[0569] Figure 59 It is a representative depiction of the angle of inclination. It can be clearly seen that the triangle is a right triangle, with 10° at the top and a right angle at the bottom. The leg of 10 milliradians has become the side of the triangle, i.e., the hypotenuse, and represents the inclined vertical section of the crosshair. However, the force of gravity acts on the vertical leg of the triangle.
[0570] Using trigonometry, the length of the vertical leg can be solved using the following formula: Cosl0° = x / 10 milliradians. Solving for x gives a value of 9.85 milliradians. Thus, in this example, although the user / shooter may have held or dialed 10 radians, they have only compensated for 9.85 radians of shooting. At long distances, this can easily miss the target.
[0571] In one embodiment, the present disclosure relates to an observation optical sight having an integrated display system that uses an active display to generate a reticle capable of compensating for firearm tilt. A user can shoot at a distance seamlessly without having to worry about the tilt angle.
[0572] In a traditional rifle sight, the reticle is a physical crosshair, which can be metal, wire, or a pattern permanently etched on glass. This means that the tilt of the reticle is always fixed. However, with active display technology for generating a real-time reticle, the digital reticle can be changed at any time by overlaying the digital reticle onto the passive image. In one embodiment, the observation optical sight has an internal tilt sensor that can immediately orient the reticle generated by the active display to compensate for the tilt angle.
[0573] Figure 60 FIG. 7 is a representative depiction of a reticle 6000 having markings and patterns that are oriented for tilt and generated by an active display of an integrated display system. The main horizontal line 6002 and the main vertical line 6004 are provided by a passive or etched or fixed reticle. The aiming point generated by the active reticle 6020 compensates for tilt and is projected or overlaid on the passive reticle. The pivot point 6010 is located at the center of the reticle. In this case, the electronic controller / microcontroller will use the information collected from the tilt angle sensor and the inclination sensor, apply software logic, and communicate with the active display to adjust the generated image aiming point 6020 to reflect the new zero position, the relevant geometry, and the holding point corresponding to the firearm orientation at that point in time. The user will fire at the digital reticle generated by the active display rather than a passive or fixed reticle.
[0574] In another embodiment, the active display of the integrated display system can generate a digital reticle by adjusting the aiming point on the digital reticle upward or downward, which compensates for tilt as well as compensates for shooting at an inclination or descent angle. This will eliminate the need for a cosine indicator, which is typically used to compensate for shooting in such cases.
[0575] D. Digital reticle with windage indicator
[0576] In a traditional rifle sight, the reticle with a wind indicator is typically a glass-etched reticle. Generally, these reticles will have a grid pattern or rows of dots to allow the user to have a reference point for aiming and compensating for wind speed. The problem with these reticles is that their shape and size are fixed because they are physically and permanently etched on a piece of glass.
[0577] In one embodiment, the present disclosure relates to an observation optical mirror having a body and a base, the base having an integrated display system having an active display for generating a digital reticle that uses a windage indicator to compensate for the distance to a target. In one embodiment, the digital reticle is overlaid on a passive reticle. By using a digital reticle overlaid on a passive reticle, the observation optical mirror can have a reticle that can adapt the real-time wind hold range to the ballistics, distance, and environment of a particular situation.
[0578] Generally, the longer the distance, the greater the effect of crosswind on the bullet. By using a digital reticle, as the distance increases, the wind hold range can be expanded to compensate for the wind value at a particular distance for the target.
[0579] Figure 61 is a representative depiction of reticle 6100. The passive reticle provides a plurality of components or markings, including a main horizontal crosshair 6102 and a main vertical crosshair 6104. The active display of the integrated display system generates and projects a target that is range-found at 500 yards 6105, and a wind hold range 6110, under particular conditions. The ends of the auxiliary horizontal lines (across the main vertical line) are equal to a windage of 5 mph, the next point is 10 mph, and the outermost point is 15 mph. The images generated from the active display 6105 and 6110 are overlaid on the passive reticle.
[0580] Figure 62 is a representative depiction of reticle 6200. The passive reticle provides a plurality of components or markings, including a main horizontal crosshair 6202 and a main vertical crosshair 6204. The active display of the integrated display system generates and projects a target that is range-found at 1000 yards 6210, and a wind hold range 6220, under particular conditions. The ends of the horizontal lines (across the main vertical line) are equal to a windage of 5 mph, the next point is 10 mph, and the outermost point is 15 mph. The images generated from the active display 6210 and 6220 are overlaid on the passive reticle. It can be seen that compared to the solution for 500 yards ( Figure 61 ), the auxiliary horizontal line 6220 extends wider, and the wind points are further spread out to the sides to compensate for the additional windage caused when the bullet travels a longer distance.
[0581] E. Reticle with center grid for second shot correction
[0582] In the past, the design of passive reticles has allowed shooters to have many reference points for shooting under various conditions and various ballistics. However, since the conditions and ballistics vary so widely, these reticles tend to have many features on them, such as a grid of lines or points, which results in the reticle appearing cluttered or confusing to the user.
[0583] In one embodiment, the present disclosure relates to a reticle system that includes a digital reticle generated using an active display, which overlaps a passive reticle. The use of the digital reticle allows information to be displayed as needed and appropriate, which eliminates the need to display certain information on the passive reticle, thereby providing a cleaner or more distinguishable passive reticle.
[0584] In one embodiment, the present disclosure relates to an observation optic having a passive or analog reticle designed to work most efficiently with an active reticle. The active reticle technology enables the observation optic to perform complex calculations and display ballistic solutions for the user. Typically, the ballistic solution will not be centered in the field of view or at the center of the passive reticle crosshairs. This allows the user to choose to keep the center of the ballistic solution stationary or turn the adjustment knob until the ballistic solution is centered in the field of view and at the center of the passive crosshairs for shooting.
[0585] In one embodiment, the present disclosure relates to an observation optic having analog and digital reticles that will enable a shooter to perform a second shot correction most effectively and efficiently while obscuring their field of view in a minimal way, as with previous passive reticles, which uses an extensive grid of lines and dots.
[0586] Figure 63 is a representative depiction of a wide-angle view of reticle 6300 at low magnification. A less obtrusive row of dots is used below the horizontal crosshair. This passive reticle can be used as a backup if the active display cannot be generated due to battery power or a malfunction of the electronics of the observation optic.
[0587] Figure 64 is a representative depiction of a close-up view of the central portion of reticle 6400. Figure 64 A view at higher magnification is provided. The image shows a small grid 6410 generated by the active display of an integrated display system, which is located at the center of the reticle. This will allow the user to accurately measure the first shot impact location for an accurate second shot correction.
[0588] In one embodiment, the grid 6410 generated by the active display is wider than it is tall. This is specifically designed because calculating the elevation angle of impact is more accurate than estimating the windage of the first shot. In this embodiment, the small plus features of the small grid are not illuminated but are very fine features, which allows for very precise measurement.
[0589] The active or digital reticle should make the first shot very close, so the central grid can be much smaller than a typical passive reticle, which requires a wide grid that must cover most of the field of view below the horizontal crosshair.
[0590] VI. Automatic brightness adjustment
[0591] As discussed throughout the application, an integrated display system allows a digital image generated by an active display to be overlaid on top of an image of an external scene. The active display is injected into the image of the external scene using the illumination portion of the display. To make the display most useful, it is desirable to have a high contrast between the brightness of the passive scene and the illuminated display so that both can be easily seen. If the display is too dim, the user will not be able to see it. If the display is too bright, the display will overpower the passive scene.
[0592] In one embodiment, the present invention relates to an observation optical mirror having a body with an integrated display system and a light sensor that can detect and compensate for a specific target brightness.
[0593] Figure 71 A representative schematic diagram of an observation optical mirror 7100 having a body 7105 and a base 7110 coupled to the body is provided. The body 7105 has an optical system for viewing an image of an external scene and a beam combiner 7120 having a photoelectric sensor 7125 and a filter 7130 located above the beam combiner 7120. This allows the photoelectric sensor to directly view the target scene without creating an obstruction in the field of view. The base 7110 has an integrated display system 7115 that has an active display for generating an image projected into the first focal plane of the observation optical mirror.
[0594] The photoelectric sensor 7125 and the filter 7130 create a high contrast between the brightness of the image of the external scene and the image generated from the active display.
[0595] In one embodiment, the transmission band of the filter in front of the photoelectric sensor can be adjusted to be narrow enough to measure only the brightness of the target without measuring additional light from the display system, which would cause measurement distortion.
[0596] VII. Observation optic with automatic ranging function
[0597] In one embodiment, the present disclosure relates to an observation optical mirror having an integrated display system that incorporates the use of a camera to assist in automatic ranging. In one embodiment, the present disclosure relates to a system that includes an observation optical mirror having an integrated display system, a camera for assisting in automatic ranging, and a laser rangefinder.
[0598] In one embodiment, the present disclosure relates to an observation optical scope having an integrated display system and a camera incorporating image recognition technology. The systems and methods disclosed herein greatly improve the speed of obtaining a target solution and eliminate the need for button presses that may affect the aiming point. Additionally, the systems and methods disclosed herein integrate artificial intelligence into the system to determine the quality of the target solution for range finding.
[0599] In one embodiment, the observation optical scope has a camera incorporating image recognition technology. In one embodiment, the camera can be attached to an observation optical system or a firearm having an integrated display system and will point to the aiming point of the sight.
[0600] In one embodiment, the camera has artificial intelligence to detect a target and communicate with an active display of the integrated display system to highlight the target. In another embodiment, the artificial intelligence system can be incorporated into the observation optical scope. In one embodiment, the artificial intelligence system can be located in a base coupled to the body of the observation optical scope.
[0601] In another embodiment, a thermal imaging camera lacking image recognition technology can be used. This will allow the thermal image to be transmitted to the active display and overlaid on the image of the external scene in the observation optical scope. The observation optical scope can be programmed to display only the "hot spots" of interest. For example, hot spots indicating human heat or vehicle heat, etc. Eliminating the artificial intelligence will greatly reduce the power consumed by the system. Additionally, all appropriate hot spots will appear in the field of view of the observation optical scope, enabling the user to evaluate each hot spot to determine if the target is valid.
[0602] After identifying a valid target, the user simply moves the observation optical scope so that the LRF indicator in the FOV is above the desired hot spot. Once the LRF indicator is aligned with the hot spot, the system will automatically trigger the LRF to range find at that hot spot. After ranging, the observation optical scope can display a hold point for the target distance or simply display the distance, and the user can use the active BDC mode and hold the appropriate measured distance to the target on the active BDC reticle.
[0603] Another additional feature of the system is that it can automatically detect if the hot spot stays within the LRF indicator long enough to achieve an effective distance. If not, it will wait to display the distance until the hot spot remains within the LRF indicator for an appropriate duration to enable effective target acquisition before displaying the solution. This will eliminate the second problem of button presses.
[0604] In one embodiment, the present disclosure relates to a technique and method that uses overlapping camera images projected into the first focal plane of the observation optical scope and combines the image with the LRF indicator to automatically range find a target.
[0605] VIII. Observation optic with energy - saving optoelectronic sensor
[0606] In one embodiment, the present disclosure relates to an observation optical mirror having an integrated display system and an energy saving system. In one embodiment, the energy saving system is located in a base coupled to the body of the observation optical mirror. In one embodiment, the energy saving system includes a proximity sensor. In one embodiment, the proximity sensor communicates with a microcontroller.
[0607] In one embodiment, when the user / operator is not observing through the observation optical mirror, the energy saving system can be used to place the observation optical mirror in a sleep or standby mode. In one embodiment, when a user / operator is detected behind the eyepiece of the optical mirror, the system and mechanism can wake up or activate the observation optical mirror.
[0608] Current methods of putting electronic devices into a sleep or standby state use a "timeout" function, which is disadvantageous if the optical mirror is used for close combat work because the optical mirror must remain on for an indefinite period as long as an operator is observing through it. An accelerometer can also be used to detect movement to turn on the system. The disadvantage of this method is that if the operator is observing, even if the operator is still observing through the optical mirror, there may be little movement of the firearm for a long period of time, and thus it enters the sleep state.
[0609] In one embodiment, the present disclosure relates to a system for saving battery power by turning on an observation optical mirror when an operator is detected behind the eyepiece of the optical mirror.
[0610] In one embodiment, the energy saving system can be used in any electro-optical mirror compatible with implementing a proximity sensor that is within a few inches of the operator's face when using the optical mirror.
[0611] In one embodiment, the present invention relates to an observation optical mirror having a body and a base connected to the body, wherein the base has a window facing the eyepiece on the back of the base.
[0612] In one embodiment, the base has a proximity sensor mounted in a bracket, and the bracket is mounted in a window at the end of the base facing the eyepiece. When the proximity sensor detects a reflection within a few inches of the window, the proximity sensor can send a signal to a microcontroller in the base or the body. The distance at which an object activates the sensor can be adjusted at the factory, or a software option can be built into the user interface so that the operator can adjust the sensitivity of the sensor or disable / enable the automatic sleep / standby function.
[0613] Figure 72is a representative depiction of an observation optical scope 7200 having a base 7205. The base 7205 has a window 7210 positioned toward the eyepiece of the body of the observation optical scope. A proximity sensor and bracket 7215 are located in the window 7210, which is positioned below the eyepiece.
[0614] Figure 73 and Figure 74 is a representative depiction of an observation optical scope 7200 having a base with an energy saving system, and the observation optical scope 7200 is mounted on a rifle. It can be seen that the operator's face will be within a few inches of the back of the optical scope. The sensor 7215 in the base 7205 of the observation optical scope 7200 will detect the reflection of the operator's face, thereby waking up the optical scope from the sleep mode. When the operator moves his / her head away from the observation position, the sensor will no longer see the reflection and place the observation optical scope in the sleep or standby mode.
[0615] IX. Observation optic with power rail
[0616] In one embodiment, the present disclosure relates to an observation optical scope having a body and a base with an integrated display system, wherein the observation optical scope can be powered by an external power source housed in a main firearm. In one embodiment, the observation optical scope has a body and a base coupled to the body, wherein electrical pins are built into the base to power the observation optical scope from the firearm. In another embodiment, the observation optical scope can be powered by electrical pins built into a remote keyboard assembly through the firearm.
[0617] In one embodiment, the present disclosure relates to a method and system for supplying additional power to an observation optical scope over an extended period of time.
[0618] In one embodiment, the present disclosure relates to an observation optical scope having a body and a base coupled to the body, wherein the base has a PCB for controlling the display, sensors, and user interface of the observation optical scope. In one embodiment, the base has a power input pin that protrudes through the base and contacts a power pad. In one embodiment, the power pad is built into a Picatinny rail.
[0619] In one embodiment, the PCB is located in a position that allows interaction with the input pins. In one embodiment, the pins are sealed on the base of the sight to keep the interior of the sight protected from the environment.
[0620] Figure 75 and Figure 76 is a representative depiction of an observation optical scope 7500 having a body and a base 7510, wherein power pins 7520 protrude through the base 7510 of the observation optical scope 7500.
[0621] Figure 77 is a representative side profile of the observation optical mirror 7500, which shows the power pins 7520 protruding through the base 7510 of the observation optical mirror 7500.
[0622] Figure 78 is a representative view of the side profile of the observation optical mirror 7500, where the base of the observation optical mirror is made transparent to show the power pins 7520 attached to the built-in PCB 7530.
[0623] In another embodiment, the power provided by the Picatinny rail on the firearm can be transmitted to the observation optical mirror through a remote keyboard for controlling the observation optical mirror. In this case, the power pins are connected to the PCB in the remote keyboard and protrude through the built-in recoil lug in the remote keyboard housing. Then, the power is sent to the base of the sight through two dedicated lines in the cable.
[0624] Figure 79 is a representative image of the top of the remote keyboard 7900.
[0625] Figure 80 is a representative side profile of the remote keyboard 7900, which shows the power pins 8010 protruding through the built-in recoil lug.
[0626] Figure 81 is a representative bottom view of the remote keyboard 7900, which shows two power pins 8010 protruding from the remote recoil lug.
[0627] Figure 82 is a representative bottom view of the remote keyboard 7900, where the cover is made transparent to show the PCB 8205 inside the remote body.
[0628] X. Observation optic using a single keyboard with multiple functions
[0629] In one embodiment, the present disclosure relates to a system that includes an observation optical mirror with an integrated display system and a remote keyboard system in which each keyboard button has more than one function. In one embodiment, the remote keyboard can control more than one aspect of the functions of the observation optical mirror, i.e., each button has more than one function. In one embodiment, the function of the button depends on the state of a control signal or software bit.
[0630] In one embodiment, the present disclosure relates to a remote keyboard that extends the control of the user / operator over the observation optical mirror and / or auxiliary devices used with the observation optical mirror.
[0631] In one embodiment, the present disclosure relates to a keyboard for observing an optical mirror and / or one or more auxiliary devices used with the observation optical mirror. In one embodiment, more than one function is assigned to a single button of the keyboard, and the desired function can be determined by software bits or separate mechanical switches. This can significantly increase the functionality of the observation optical mirror.
[0632] In a representative embodiment, in a first mode, the button can change the brightness of the display, while in a second mode, the same button can activate an infrared indicator on the system. Performing more than one function using the same button enables the remote keyboard to be small and simple, with the minimum number of buttons required.
[0633] Figure 83 FIG. 7 is a representative depiction of a keyboard having three buttons. The remote keyboard associated with the observation optical mirror has 3 buttons. The top button 8305 is used to increase the brightness of the display, the middle button 8310 is used to fire a laser rangefinder to range a target, and the bottom button 8315 is used to decrease the brightness of the display. The function of each button depends on the operating mode.
[0634] In one embodiment, the keyboard can have 2, 3, 4, 5, 6, 7, 8, 9, 10 or more than 10 operating modes. In one embodiment, the communication of the keyboard with the processor can set 10 to 50 operating modes for the keyboard. For example, a keyboard communicating with a processor having 10 operating modes of the keyboard will provide 10 functions for each button, and its function is determined by the operating mode.
[0635] Several methods can be used to change the function of the button. In one embodiment, when the user / operator presses and holds a button on the remote control for a period of time, the microcontroller changes the function of one or more buttons. In one embodiment, the operator can hold down one of the 3 buttons for a long time, for example, hold down for 1 second, which will signal the microcontroller inside the observation optical mirror to change the bits that assign new functions to the buttons. In one embodiment, holding down the top button 8305 for a period of time can set mode A, holding down the middle button 8310 for a period of time can set mode B, and holding down the bottom button 8315 for a period of time can set mode C. Changing the engagement time of each button can activate other operating modes. For example, holding down button 8305 for 5 seconds can activate mode A, and quickly clicking button 8305 5 times can activate mode F.
[0636] In another embodiment, the function of the remote keyboard button can be changed by a separate mechanical switch on the observation optical mirror. In one embodiment, the mechanical switch can have 3 different positions, which communicate with 3 separate bits or programs in the microcontroller. These bits or programs can be used to assign various functions to the remote keyboard buttons.
[0637] is shown Figure 84 Representative examples. The observation optical mirror has a switch 8400 that communicates with the remote keyboard 8300. The first setting 8405 can assign the function of increasing the display brightness to the top button 8305 of the remote keyboard 8300, the middle button 8310 can fire the laser rangefinder, and the bottom button 8315 can decrease the display brightness. When the mechanical switch 8400 is set to the second setting 8410, the functions of the top button 8305 and the bottom button 8315 can be programmed to turn on and off the auxiliary aiming laser on the observation optical mirror, while the middle button 8310 can still be programmed to fire the laser rangefinder. When the mechanical switch 8400 is set to the third setting 8415, the functions of these three buttons can be changed again. For example, if the observation optical mirror is equipped with a digital magnetic compass and the position and landmark data have been saved in the memory of the microcontroller, information about the object position (augmented reality data) can be displayed within the field of view of the observation optical mirror.
[0638] In one embodiment, the keyboard communicates with the processor of the observation optical mirror, and the processor allows different operation modes to be assigned to each button or switch of the keyboard. For example, in one operation mode, the buttons of the keyboard have specific functions for marking targets of interest. The operator can use the laser rangefinder to measure the distance to the target and use the heading data from the digital magnetic compass to "mark" the target of interest within the field of view. Functions specifically suitable for this task can be assigned to the buttons on the keyboard.
[0639] The center button on the keyboard can be used to fire the laser rangefinder to measure the distance to the target. After determining the distance to the target, the top button and the bottom button can be used to select from a predefined list of descriptors to mark the target, such as "landmark", "friendly", "hostile", "unknown", etc. Once the operator has completed this action, the mechanical switch can be changed to quickly assign the functions back to the remote keyboard buttons, enabling the operator to change the brightness settings, activate the infrared laser, or obtain the ballistic solution for the lower limit of the target.
[0640] XII. Observation optic using a relative coordinate mapping system
[0641] In one embodiment, the present disclosure relates to techniques and methods for using an observation optical mirror with an integrated display system to accurately mark and track targets using a relative coordinate mapping system and / or drone technology.
[0642] Soldiers need to be able to accurately identify the location of enemy targets and share that location with other soldiers, for close air support, etc., and be able to easily see these targets by overlaying the target within the field of view of their main optical sight. The most obvious way to achieve this is to use a combination of GPS, compass heading, altitude, tilt, and range sensors. However, relying on GPS has some drawbacks, such as the GPS signal requires a direct line of sight to the GPS satellite, which is not always possible. Using relative coordinate technology and / or using unmanned aerial vehicles can reduce the need for GPS. When combined with an observation optical sight with an integrated display system, relative coordinate technology becomes feasible.
[0643] In one embodiment, the user will be able to point an observation optical sight with an integrated display system at a landmark or target and "mark" it. If the user "marks" multiple targets, a relative position map can be created from the marked targets. These marked targets can be transmitted to the observation optical sights of other users, and the other users will see those marked targets displayed in their field of view. Then, all of this target data will be locally stored in one or more memory devices in the observation optical sight.
[0644] In one embodiment, the user can also use unmanned aerial vehicles as an alternative to marking targets, or as a supplement to marking targets. This can be achieved by launching a "cloud" consisting of many small or micro unmanned aerial vehicles to fly over the battlefield and start annotating and marking landmarks. These unmanned aerial vehicles will contain cameras and appropriate sensors. The unmanned aerial vehicles can share this information with each other and return it to the user, enabling the user to display this information in the active display of their own observation optical sight.
[0645] By using relative coordinate technology and / or an unmanned aerial vehicle cloud, the drawbacks of GPS can be overcome:
[0646] · Using multiple users and multiple observation optical sights, the stored target data will have inherent redundancy. When using an unmanned aerial vehicle cloud, the redundancy can be further increased. With redundancy, the likelihood of signal or data loss is greatly reduced.
[0647] · GPS needs to send and receive data with satellites in orbit over long distances. By using other users located in the same combat space, or using an unmanned aerial vehicle cloud located in the same combat space, the network can be closer to the users and targets, thereby improving the accuracy of user and target coordinates.
[0648] · Since the number of GPS satellites is limited, GPS is prone to jamming. By utilizing users and / or an unmanned aerial vehicle cloud, it becomes more difficult to jam all signals and creates more redundancy.
[0649] · The need for a GPS module is eliminated, thereby reducing the volume of the observation optical sight.
[0650] XIII. Optional embodiments of magnification tracking
[0651] In one embodiment, the present disclosure relates to an observation optical mirror having magnification tracking capabilities. In one embodiment, the present disclosure relates to an observation optical mirror having a system or device configured to track a magnification setting. In another embodiment, the present disclosure relates to an observation optical mirror having an integrated display system, the observation optical mirror having magnification tracking capabilities. In one embodiment, the present disclosure relates to an observation optical mirror having means coupled to an erecting system of the observation optical mirror, wherein the means has a material with more than two portions, and the more than two portions have different light absorption rates / reflection rates
[0652] As described above, in one embodiment, a material having a transition from bright to dark can be placed on the erecting system of the observation optical mirror. When the magnification lever is rotated, the material rotates, and a light sensor can be used to measure the change in brightness from a reflected target. Representative examples are Figures 85 - 87 shown.
[0653] As Figures 85 - 87 shown, the observation optical mirror 8530 has an outer sleeve guard 8570 mounted on the erecting lens system 8520. The reflective material 8510 is mounted on the outer sleeve guard 8570. This allows a light sensor or a photoelectric sensor 8550 to measure a wide range of reflectance or absorptance from the reflective material 8510. The outer sleeve guard 8570 is designed such that it does not impede the cam pin 8580 when the cam pin 8580 moves within the erecting system cam curves 8580. In one embodiment, the outer sleeve guard 8570 is located near the magnification adjustment ring 8540.
[0654] In one embodiment, the present disclosure relates to an erecting lens system, which includes an erecting tube having an erecting lens assembly; means surrounding at least a portion of the erecting tube, wherein the means has a material with at least two regions, and each of the at least two regions has a different light absorption rate or reflection rate. Figures 67 - 70 The photoelectric sensor described in
[0655] In one embodiment, the present disclosure relates to an erecting lens system, which includes an erecting tube having an erecting lens assembly; a cam sleeve coupled to the erecting tube; an outer sleeve guard coupled to the cam sleeve, wherein the outer sleeve guard has a material with at least two regions, and each of the at least two regions has a different light absorption rate or reflection rate.
[0656] The devices and methods disclosed herein can be further described in the following paragraphs:
