Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application is a continuation of and claims priority to U.S. Provisional Application No. 63 / 298,594, filed on January 11, 2022, which is incorporated by reference in its entirety herein.

[0002] (Technical field) The present disclosure relates to a viewing optics. In one embodiment, the viewing optics has a remote device with an illumination source. In one embodiment, the viewing optics has an active display system that generates an image that is projected onto a first focal plane of an optical system. [Background technology]

[0003] Riflescopes have been in use for well over a century, and although the quality and features of these devices have advanced considerably over the years, the core components (and limitations on these components) used in their design, manufacture and application are still largely unchanged from 100 years ago. Riflescopes produce a magnified or non-magnified image of a scene remote from the shooter on a focal plane that coincides with an aiming feature, or reticle. The reticle consists of wires or material deposited in a pattern on the glass surface and is used as an aiming reference that corresponds to the trajectory of the rifle on which it is mounted. The reticle may also have specific features to assist the shooter in making distance judgments and compensating for bullet deflection at different distances.

[0004] Turrets are also used to adjust the reticle position relative to the target to compensate for bullet deflection. This is a highly developed and reliable system that can be used in the hands of an experienced and skilled shooter to make difficult long-range shots. With the aid of a Laser Range Finder (LRF) and a ballistic computer, and careful attention to detail, an experienced shooter can consistently hit the target at the maximum effective range of his firearm by making the necessary mechanical adjustments to the firearm and / or executing a precise hold on the reticle pattern.

[0005] While this system works well, there is always a need to improve it, especially to reduce the complexity involved in hitting targets at long distances. To effectively hit long distance targets, a large amount of information is required for each shot, and the shooter must be able to process this information and make the correct decisions and calculations in real time. In addition to the riflescope, other tools are required by the shooter to ensure accurate shot placement. For example, a bubble level mounted on the exterior of the riflescope is required to ensure the optic is level before executing a shot. This requires the shooter to move their head away from the pupil of the optic to check their level.

[0006] A laser rangefinder and ballistic computer are also required to measure target distance and calculate bullet trajectory, again requiring the shooter to keep that data in mind when turning his attention to the external device and then making the necessary adjustments. When using a weapon-mounted laser rangefinder, the shooter must take special care to ensure that the aiming point of the optic is closely aligned with the aiming point of the LRF.

[0007] Moreover, a key aspect of riflescope use is that they are only useful during daylight hours. As night sets in, a light source must be provided. Additionally, thermal and / or night vision devices must be attached to the weapon in front of the riflescope. These devices capture other forms of radiation that are not visible to the human eye due to their low wavelength or intensity. These devices then recreate or enhance an image of the scene and reimage the scene onto the riflescope objective lens. These devices, which are necessary to be effective in low light conditions, are also heavy and large.

[0008] In the specific case of a thermal imaging device, a thermal scene is imaged via infrared optics onto a specialized thermal sensor. The image is then reproduced on a microdisplay, which is then reimaged onto the objective lens of a riflescope with visible optics. The two separate optics required to accomplish this result in a rather large, heavy, and expensive device.

[0009] Previous devices have attempted to address some of these problems in various ways with varying degrees of success. However, all attempts to date have implemented these solutions in the second focal plane of the optical system. This is extremely disadvantageous, since only the second focal plane of a riflescope has good correlation with the image of the scene at a single magnification setting. Aiming point locating is also accurate only at one point in the turret adjustment. Due to this significant limitation, additional electronics are required to track the variables of the rest of the system and adjust the aiming point accordingly. Other systems provide approximate aiming point solutions by illuminating features at general coarse intervals instead of selecting a point at a quasi-infinite range. Weaker systems can only display basic information such as the distance to the target or the current weather. Summary of the Invention [Problem to be solved by the invention]

[0010] Thus, there remains a need for system integration to alleviate the heavy processing requirements on the user, including a way for the user to effectively position the light source. This integration is also needed to reduce the "time to engagement" that is traditionally quite long when multiple devices must be referenced and calculations and coordination must be performed. And finally, the size and weight of the additional devices required to effectively use a riflescope in low light conditions can be reduced with a more integrated solution.

Further, those skilled in the art will appreciate that various combinations of features and functions may be incorporated into add-on modules for retrofitting any type of existing fixed or adjustable weapon sight.

[0073] When an element or layer is referred to as "on," "connected to," or "coupled to" another element or layer, it will be understood that the element or layer can be directly on, or directly connected or coupled to, the other element or layer. Alternatively, intervening elements or layers may be present. In contrast, when an element is referred to as "directly on," "directly connected to," or "directly coupled to" another element or layer, there are no intervening elements or layers present.

[0074] Like numbers refer to like elements throughout. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0075] In this specification, terms such as first, second, etc. may be used to describe various elements, components, regions, and / or sections, but it will be understood that these elements, components, regions, and / or sections are not limited by these terms. These terms are used only to distinguish one element, component, region, or section from another element, component, region, or section. Thus, a first element, component, region, or section discussed below can be referred to as a second element, component, region, or section without departing from this disclosure.

[0076] Spatially relative terms such as "below," "down," "lower," "above," "upper," and the like may be used herein for ease of description to describe the relationship of one element or feature to another element(s) or feature(s) as shown in the figures. It will be understood that the spatially relative terms are intended to encompass various orientations of the device during use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures were inverted, an element described as being "below" or "below" the other element or feature would then be oriented "above" the other element or feature. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein can be interpreted accordingly.

[0077] I. Definition Numerical ranges in this disclosure are approximate and therefore may include values ​​outside the range unless otherwise indicated. Numerical ranges include all values ​​from the lower limit to the upper limit, inclusive, in increments of one unit, provided that there is a separation of at least two units between any lower limit and any upper limit. As an example, if a compositional, physical or other property, such as molecular weight, viscosity, etc., is between 100 and 1000, all individual values ​​such as 100, 101, 102, etc., as well as subranges such as 100 to 144, 155 to 170, 197 to 200, etc., are expressly recited. For ranges containing values ​​less than 1 or containing decimals greater than 1 (e.g., 1.1, 1.5, etc.), one unit is considered to be 0.0001, 0.001, 0.01, or 0.1, as appropriate. In ranges containing single digit numbers less than 10 (e.g., 1 to 5), one unit is typically considered to be 0.1. These are merely examples of what is specifically intended, and all possible combinations of numerical values ​​between the lowest and highest values ​​listed shall be considered to be expressly set forth in this disclosure. Numerical ranges for distances from a user of the device to a target are provided, among other things, within this disclosure.

[0079] As used herein, "active display" includes image-generating 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), are characterized by having an image and a light source in a single device, so no external light source is required. This minimizes system size and power consumption while providing excellent contrast and color space. OLEDs are made of ultra-thin organic semiconductor layers that light up when connected to a voltage (charge carriers are injected and the brightness is mainly proportional to the forward current). The main layer comprises multiple organic materials in sequence (e.g., charge transport layers, blocking layers, and emissive layers, each with a thickness of a few nanometers), which are interposed between an anode and a cathode. The terms "active display", "digital display" and "microdisplay" are used interchangeably.

[0080] As used herein, an "erect sleeve" is a protrusion from an erect lens mount that engages with a slot in the erect tube and / or cam tube, or serves a similar purpose. It may be integral to the mount or may be removable.

[0081] As used herein, an "erecting tube" is any structure or device having an opening for receiving an erecting lens mount.

[0082] As used herein, a "firearm" is a handheld, often barreled weapon that fires one or more projectiles powered by the action of explosive force. As used herein, the term "firearm" includes handguns, long guns, rifles, shotguns, carbines, automatic weapons, semi-automatic weapons, machine guns, light machine guns, automatic rifles, and assault rifles.

[0083] As used herein, the term "floodlighting" refers to a large amount of light provided to a particular area. In one embodiment, the light is provided by one or more light emitting diodes.

[0084] 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 concentrator optics. In yet another embodiment, the integrated display system includes an active display, concentrator optics, and a reflective surface.

[0085] In one embodiment, an integrated display system may be used to generate a digital image on an active display and direct the digital image into a first focal plane of an optical system for simultaneous viewing of the digital image and an image of an external scene. As used herein, "aiming system" refers to one or more optical devices and other systems that assist a person in aiming a firearm or other implement.

[0086] As used herein, the term "mark" can include any of a variety of visually perceptible lines, circles, dots, crosshairs, horseshoe patterns, geometric shapes, symbols, numbers, letters, signs, or symbols.

[0087] As used herein, the term "passive reticle" refers to a reticle with fixed marks that cannot be altered by a user. A typical example of a passive reticle is an etch-and-fill reticle. Another example is a holographic reticle, where the marks cannot be altered by a user. A passive reticle can be located in the first focal plane, in the second focal plane, or in both the first and second focal planes.

[0088] As used herein, the term "observation optics" refers to a device used by a shooter or observer to select, identify, or monitor a target.

The image of the target presented to the shooter by the "observation optics" device may be unaltered or may be enhanced, for example, by magnification, amplification, subtraction, superposition, filtering, stabilization, template matching, or other means. The target selected, identified or monitored by the "sighting optics" may be within the shooter's line of sight, out of the shooter's line of sight, or the shooter's line of sight may be obstructed while the target acquisition device presents the shooter with a focused image of the target. The image of the target acquired by the "sighting optics" may be, for example, analog or digital, and may be shared, stored, archived or transmitted within a network of one or more shooters or observers, for example, by video, physical cable or wire, IR, radio wave, cellular connection, laser pulse, optical, 802.11b or other wireless transmission using protocols such as html, SML, SOAP, X.25, SNA, Bluetooth™, serial, USB, or other suitable image delivery methods. The term "sighting optics" is used synonymously with "optical sight."

[0091] II.Optical observation equipment FIG. 1A shows a conventional design of a riflescope, which is a representative example of a viewing optic. FIG. 1B shows an exemplary viewing optic 10 according to an embodiment of the present disclosure. Specifically, FIG. 1B shows a riflescope. More specifically, the riflescope 10 has a body 38 that encloses a movable optical element 15. The body 38 is an elongated tube that tapers from a larger opening at its front 40 to a smaller opening at its rear 42. An eyepiece 56 is mounted to the rear of the scope body, and an objective lens 54 is mounted to the front of the scope body. The central axis of the movable optical element defines the optical axis 44 of the riflescope.

[0092] The elevation turret 12 and windage turret 48 are two dials often found on the exterior center of the body 38. They are incrementally marked by indicia 20 on their perimeter 11 and are used to adjust the elevation and windage of the movable optical elements for point of impact changes. The dials protrude from a turret housing 50. The turrets are oriented so that the elevation turret's axis of rotation 46 is perpendicular to the windage turret's axis of rotation 52.

[0093] FIG. 1C shows a cross-sectional view of the aiming device of FIG. 1B with the basic components of the optical system 14 and the movable optical element 15. As shown in FIG. 1C, the optical system 14 includes an objective lens system 16, an erection system 25, and an eyepiece lens system 18. Although FIG. 1C shows a riflescope having a body 38, the optical system 14 can be used in other types of aiming devices as well. The erection system 25 can be included in the movable optical element 15. The erection system 25 can include a variable magnification lens element or a zoom element 25A. In FIG. 1C, the movable optical element 15 also includes a first focal plane reticle 55 and a second focal plane reticle 57, along with a condenser 22. In use, adjustment of the turret assembly 28 and the turret screw 29 provides adjustment of the movable optical element 15.

[0094] The movable optical element 15 is adjusted by rotating the turret assembly 28 one or more clicks. As the turret rotates, the turret screw 29 moves in and out of the scope, which pushes the erection tube. The erection tube is spring loaded so that as the turret screw is adjusted, it positions the erection tube against its bottom surface. The erection tube provides a smaller optical image of the overall image. As the erection tube is adjusted, the position of the reticle is changed relative to the image.

[0095] The reticle is a circular, planar or flat transparent panel or disk mounted within the scope body in perpendicular relationship to the optical axis or line of sight through the scope, positioned between the objective lens element 54 and the erecting lens element at a location that is typically considered the front focal plane of the optical system within the housing. In one embodiment, the reticle includes fine etched lines or hairline markings with central vertical and horizontal hairlines that intersect orthogonally or perpendicularly at a center point.

[0096] In one embodiment, the observation optics can have a parallax adjustment knob 70 or focus knob, as shown in FIG. 1D. Parallax occurs when the optical plane of the target image is not coplanar with the optical plane of the reticle image. As a result of the offset between the two optical planes, the reticle may appear to move relative to the target when the shooter moves his eyes around the reticle center. This parallax error may result in a shift in the point of impact upon firing. Parallax adjustment of the observation optics allows the shooter to eliminate optical errors at different distances by allowing the optical system to adjust to display the target image and the reticle image in the same optical plane. Parallax correction does not change the focus of the reticle or the image, but simply moves the plane in which these two objects are in focus so that they share the same plane (coincide).

[0097] As shown in FIG. 1D, the observation optics can have a side wheel attached to a rotatable parallax adjustment knob 70. The larger diameter of the side wheel provides more space for applied markers, such as range markers, and is easier for the shooter to rotate and read when in use. The larger diameter of the side wheel helps improve the accuracy and resolution of the range markers.

[0098] 1E shows a close-up of optical system 14 in cross section, illustrating how light rays travel through optical system 14. It is well known in the art that optical system 14 can have additional optical components, such as condenser 22, and that certain components, such as objective system 16, erector system 25, and eyepiece system 18, can themselves have multiple components or lenses.

[0099] In one embodiment, the viewing optics can include a focus cell with one or more adjustable lenses to provide parallax adjustment, in one embodiment, the one or more adjustable lenses are one or more parallax lenses.

[0100] In one embodiment, a focusing lens is positioned between the eyepiece and the objective lens, the relative distance between the focusing lens and the objective lens being adjustable to provide parallax adjustment, and an erecting lens is positioned between the eyepiece and the focusing lens, the relative distance between the erecting lens and the objective lens being adjustable to provide magnification adjustment.

[0101] III. Observation optics with active display In one embodiment, the present disclosure relates to a viewing optic having an active display that generates a digital image and projects the digital image onto a first focal plane of the viewing optic. In one embodiment, the present disclosure relates to a viewing optic having an analog reticle and a digital image, including but not limited to a digital reticle, that is viewed by a user when looking through the viewing optic. In one embodiment, the viewing optic can be used with an external laser range finder with ballistic calculation capabilities.

[0102] In one embodiment, the viewing optics includes a movable erection tube with an analog or glass etched reticle attached to the erection tube such that the analog or glass etched reticle moves in conjunction with the erection tube. In one embodiment, the digitally implemented reticle does not move in conjunction with the erection tube. Thus, the digital reticle is accurate regardless of the position of the turret or erection tube.

[0103] In one embodiment, the present disclosure relates to a viewing optic with a digital display that can be introduced into a first focal plane of the viewing optic such that the image of the digital display on the first focal plane is not tied to the movement of the erection tube. In one embodiment, the display can provide a user with an accurate ballistic aim hold point regardless of the position of the riflescope erection tube / turret.

[0104] In one embodiment, the present disclosure relates to a viewing optic with an aim point that is independent of the position of the erecting tube and / or the position of the turret of the viewing optic. In one embodiment, if the ballistically determined aim point is outside the field of view of the erecting unit, the turret can be rotated to bring the ballistically determined aim point into the field of view.

[0105] In one embodiment, the observation optical instrument comprises a main optical system consisting of an objective lens system that focuses an image from a target onto a first focal plane (hereinafter referred to as the "FFP target image"), followed by an erect 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 disposed between the objective lens system and the FFP target image, and an eyepiece lens system that collimates the SFP target image so that it can be viewed by the human eye, and a second optical system.

[0106] In one embodiment, the second optical system includes an active display and a lens system that focuses light from the active display. The image from the digital display is directed to a beam combiner such that the digital image and the target image from the objective lens system are combined at the first focal plane for simultaneous viewing. In one embodiment, the second optical system can include reflective materials, including but not limited to mirrors.

[0107] Referring to the above description, the digital display is introduced into the main optical system between the objective lens system and a first focal plane, and then focused onto the first focal plane. At the first focal plane, both the digital image from the digital display and the analog / glass-etched reticle attached to the erect lens system share the same plane. However, the analog reticle is attached to a movable erect lens system, whereas the image from the digital display is not. Thus, if the erect lens system is moved, the analog reticle will move, but the digital image will remain stationary.

[0108] In one embodiment, the sighting optics may be rigidly mounted to the firearm. In another embodiment, a laser range finder may be mounted to either the firearm or the sighting optics. The laser range finder measures the distance to a target, calculates the ballistic trajectory to hit the target, and provides that information to an active display to show the exact aim point along with the point of impact of the rifle bullet.

[0109] Because the laser rangefinder is rigidly mounted to the viewing optics and the aim point does not move, it is important that the digital image remain stationary. This allows the digital laser designator to correspond to the laser by default, and then the digital display to be digitally adjusted so that the two always remain aligned, no matter how the erector lens system is moved.

[0110] Additionally, because the firearm barrel is rigidly mounted to the viewing optics, the aim point of the barrel does not change relative to the digital display, allowing the digital aim point to initially correspond to the firearm barrel at the initial "sight-in" distance, and then the digital display to be digitally adjusted so that the two always remain aligned.

[0111] If it becomes necessary to shoot at a distance different from the initial sight-in distance, the laser rangefinder can measure the distance and then perform ballistic calculations to determine a new location for the aim point. Since this new aim point location will always be relative to the initial sight-in distance, the riflescope only needs to adjust the aim point on the digital display to correspond to the new aim point.

[0112] A side benefit of this system is that because the digital aim point is stationary, the accuracy of the turret that adjusts the position of the erector tube with a reticle having predetermined marks at regular intervals can be easily tested on the viewing optics. As the erector tube moves, the reticle can be measured against the stationary digital aim point to verify that the dial adjustments on the turret match the amount of movement measured between the digital aim point and the reticle mounted on the erector lens system.

[0113] IV.

In one embodiment, the base is attached to a bottom of the body. In one embodiment, a gasket is used to seal the body and the base.

[0115] In one embodiment, the present disclosure relates to a riflescope having a body with an optical system for generating an image of an external scene, and a base coupled to the body with an integrated display system for generating a digital image and directing 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.

[0116] In another embodiment, the present disclosure relates to a riflescope having a body with an optical system for generating an image of an external scene, and a base coupled to the body with an integrated display system having an active display for generating an image and directing the generated image to a first focal plane of the optical system to provide simultaneous viewing of the generated image and the image of the external scene when looking through an eyepiece of the scope body.

[0117] 2 displays a side view of a riflescope 200 having a body 210 and a base 220. In one embodiment, the base 220 is separable from the body 210. The base 220 is attached to one end of the scope body near the magnification ring 212 and to the other end of the scope 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 scope body and the base are made of different materials.

[0118] In one embodiment, the base 220 is approximately the length of the body upright tube.

[0119] In one embodiment, the base has an integrated display system capable of generating and displaying situational, geographical, and ballistic information in the first focal plane of the observation optics, including, but not limited to, real-time ballistic solutions; detection and tracking of in-flight tracer bullets for next round ballistic correction; weapon pointing angle tracking using integrated high performance inertial sensors; precision pointing angle comparison for advanced ballistic targeting and correction; target location and designation; air pressure, humidity, and temperature; anti-friendly fire and situational awareness data processed by the device and viewable while aiming; reticle targeting corrections beyond the scope field of view for advantageous ballistic drop corrections at long ranges; and weapon, round, and environmental characterization data.

[0121] In one embodiment, the observation optics may communicate with one or more devices wirelessly, while in another embodiment, the observation optics may communicate with one or more devices via a physical cable.

Main unit In one embodiment, the body is in the form of an elongated tube tapering from a larger opening at the front to a smaller opening at the rear, with an eyepiece mounted at the rear of the elongated tube and an objective lens mounted at the front of the elongated tube. In one embodiment, the first housing is the body of a riflescope.

[0123] In one embodiment, the body has a viewing input end and a viewing output end, which may be aligned and aligned along a viewing optical axis 44 (FIG. 1B). An object or target passes through the viewing input end, along the viewing direct viewing optics, and out the viewing output end for direct viewing by the user's eye. The body may include an objective lens or lens assembly at the viewing input end. A first focal plane reticle may be positioned along the viewing optical axis A and spaced from the objective lens assembly.

[0124] In one embodiment, the image or image inversion lens assembly can be positioned and spaced rearward from the first focal plane reticle along the viewing optical axis A. To invert the image, an erection tube with an erect image system is placed in the body between the objective lens and the eyepiece. This gives the image the correct orientation for land viewing. The erect image system is typically housed in the erection tube.

[0125] The inverting lens assembly or erect imaging system may comprise one or more lenses spaced apart from one another. The erect imaging system may include one or more movable optical elements, such as a focusing lens movable along its optical axis to adjust the focus of the image, and a magnifying lens movable along its optical axis to optically magnify the image at the back focal plane so that the target appears closer than it actually is. Typically, the erecting assembly includes a mechanical, electromechanical, or electro-optical system for driving the coordinated movement of the focusing lens and one or more variable magnification lens elements of the magnifying lens to provide a continuously variable magnification range over which the erecting assembly produces a focused, erect image of a distant target at the back focal plane.

[0126] Variable magnification can be achieved by providing a mechanism for adjusting the position of the erecting lenses relative to each other within the erecting tube. This is typically done by using a cam tube that fits snugly around the erecting tube. Each erecting lens (or group of lenses) is attached to an erecting lens mount that slides within the erecting tube. An erecting sleeve attached to the erecting lens mount slides in a straight slot in the body of the erecting tube to maintain the orientation of the erecting lens. This sleeve also engages an angled or curved slot in the cam tube. As the cam tube rotates, the erecting lens mount moves lengthwise within the guide tube, changing the magnification. Each erecting lens has a unique slot in the cam tube, and the configuration of these slots determines the amount and rate of magnification change when the cam tube is rotated.

[0127] The second focal plane aperture can be positioned and spaced rearward along the observation optical axis A from the image inversion assembly. The eyepiece assembly can be positioned and spaced rearward along the observation optical axis A at the eyepiece from the second focal plane aperture. The eyepiece assembly can include one or more lenses spaced apart from one another. In some embodiments, the observation optical axis A and the direct viewing optics can be folded.

[0128] In one embodiment, the body includes a beam combiner. In one embodiment, the beam combiner can be positioned on and optically coupled to the observation optical axis 44 as shown in FIG. 1B. In one embodiment, the beam combiner can be positioned near the observation optical reticle. In another embodiment, the beam combiner can be positioned near the observation optical reticle in the first focal plane.

[0129] In one embodiment, the beam combiner is positioned between the objective lens assembly and the first focal plane.

[0130] In yet another embodiment, the body includes a beam combiner, and the beam combiner is not located near the eyepiece assembly. In one embodiment, the beam combiner is not located below the eyepiece assembly.

[0131] In one embodiment, the body includes a beam combiner that is positioned closer to the objective lens assembly than to the eyepiece lens assembly within the main tube of the viewing optics.

[0132] 3 displays a cutaway side view of riflescope 300 with body 210 and base 220. As shown, riflescope 300 has an objective lens assembly 310, a beam combiner 320, a first focal plane 330, a second focal plane 350, and an eyepiece lens assembly 360. Beam combiner 320 is positioned between objective lens assembly 310 and first focal plane 330.

[0133] In one embodiment, the viewing optics 400 can have a body 210 that is split longitudinally to allow for assembly of associated lenses and circuitry into the base 220. Figure 4 is a representative example of a longitudinally split main tube 210 of a riflescope 400. Figure 4 shows the split line 410 of the longitudinally split main tube. A split 420 on the bottom side of the body 210 allows for the coupling of a base 220 with an integrated viewing system.

[0134] In one embodiment, the bottom side of the body has a longitudinal division, hi one embodiment, the longitudinal division is approximately the length of the base that joins the body.

[0135] In one embodiment, the body does not have an active display.

[0136] 1. Beam Combiner In one embodiment, the body of the observation optics comprises a beam combiner. In one embodiment, the beam combiner is one or more prism lenses (the prism lenses constitute the beam combiner). In another embodiment, the body of the riflescope comprises a beam combiner for combining an image generated from the integrated viewing system with an image generated from the observation optics along the observation optical axis of the riflescope. In one embodiment, the integrated viewing system is located in a separate housing separate from the body. In one embodiment, the integrated viewing system is in a first housing or in a base that mates with the body. In one embodiment, the integrated viewing system is in a cavity of a base that mates with the first housing or in the body.

[0137] In one embodiment, a beam combiner is used to combine an image generated from the integrated display system with an image from an optical system for observing an external image, where the optical system is located in the riflescope body and in front of a first focal plane in the body, and then the combined image is focused on the first focal plane, so that the generated image and the observed image do not move relative to each other. With the combined image focused on the first focal plane, the aiming reference generated by the integrated display system is accurate regardless of the adjustment of the movable erector system.

[0138] In one embodiment, the beam combiner can be aligned with the integrated display system along the display optical axis and positioned along the observation optical axis of the viewing optics in the body of the riflescope, thereby allowing the image from the integrated display system to be directed onto the observation optical axis and superimposed on the field of view of the viewing optics.

[0139] In another embodiment, the beam combiner and the integrated display system are in the same housing. In one embodiment, the beam combiner is about 25 mm from the objective lens assembly.

[0140] In one embodiment, the beam combiner is about 5 mm away from the objective lens assembly, hi 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.

[0141] In yet other embodiments, 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.

[0142] 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, hi yet another embodiment, the beam combiner is positioned at a distance between 3 mm and 10 mm from the objective lens assembly.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] In yet another embodiment, the body has a beam combiner located below the elevation turret on the outer central portion of the scope body.

[0149] In one embodiment, the beam combiner can have a partially reflective coating or surface that reflects the active display output from the integrated display system, or at least a portion thereof, onto the viewing axis and redirects it to the observer's eye in the eyepiece, while still providing good transmissive transparency quality to the direct viewing optics path.

[0150] In one embodiment, the beam combiner can be a cube made of optical material, such as optical glass or plastic material, with a partially reflective coating. The coating can be a uniform, neutral reflective coating, or can be matched with a polarizing, spectrally selective, or patterned coating to optimize both the transmission and reflection characteristics within the eyepiece. The polarization and / or color of the coating can be matched to the active display. This optimizes the reflectivity and efficiency of the display optical path while minimizing the impact on the transmission path of the direct viewing optics.

[0151] Although the beam combiner is shown as a cube, in some embodiments the beam combiner can have different optical path lengths for the integrated viewing system and direct viewing optics 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 in the path of the direct viewing optics transverse to the optical axis A.

[0152] In one embodiment, the position of the beam combiner can be adjusted relative to the reflective material to eliminate errors, including but not limited to errors due to parallax. The position of the beam combiner can be adjusted using a screw system, a wedge system, or any other suitable mechanism.

[0153] In one embodiment, the position of the beam combiner can be adjusted relative to the erection tube to eliminate errors including, but not limited to, errors due to parallax.

[0154] 2. Parallax System In one embodiment, the body comprises a parallax adjustment system, hi one embodiment, the parallax adjustment system uses a device for connecting the focus cell to the parallax adjustment element.

[0155] In one embodiment, the viewing optics disclosed herein has a body with a focus cell positioned closer to an objective lens end than a conventional focus cell and a beam combiner positioned in the space conventionally occupied by the focus cell, hi one embodiment, a connecting element connects the focus cell to the parallax adjustment element.

[0156] In a typical riflescope, as shown in Figures 5A and 5B, the parallax knob 510 is connected to the focus cell via a simple cross pin 520 that rides on a cam groove 530 in the parallax knob, translating the rotational motion of the parallax knob into linear motion in the focus cell. However, in some embodiments disclosed herein, the focus cell is shifted towards the objective lens, and therefore a connection device is required to connect the focus cell to the parallax adjustment element.

[0157] The parallax adjustment system can eliminate or reduce parallax error between an image of an active display and a reticle within the body of the viewing optics. The parallax adjustment system disclosed herein enables the viewing optics to merge an image of a digital display and an image of an external scene into a first focal plane (FFP) of the optical system without parallax error.

[0158] In another embodiment, the focus cell is positioned closer to the objective lens side of the body than the focus cell of a conventional riflescope. In one embodiment, the focus cell is shifted closer to the objective lens by about 5 mm to about 50 mm than the focus cell of a conventional riflescope. In one embodiment, the focus cell is shifted closer to the objective lens by at least 20 mm than the focus cell of a conventional riflescope. In one embodiment, the focus cell is shifted closer to the objective lens by at least 10 mm than the focus cell of a conventional riflescope. In yet another embodiment, the focus cell is shifted closer to the objective lens by 50 mm or less than the focus cell of a conventional riflescope. In one embodiment, the focus cell is shifted closer to the objective lens assembly by 30 mm than the position of the focus cell in a Vortex Diamondback riflescope, a Vortex Viper riflescope, a Vortex Crossfire riflescope, or a Vortex Razor riflescope.

[0159] In one embodiment, the focus cell is shifted closer to the objective lens side of the viewing optics by a distance including, but not limited to, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, and 40 mm compared to the focus cell of a conventional riflescope.

[0160] In one embodiment, a device connects the shifted focus cell to an adjustment knob. In one embodiment, the device allows for remote positioning of a parallax adjustment lens located within the focus cell. In one embodiment, the mechanical device is a push rod, rod, or shaft.

[0161] In one embodiment, the rods are about 5 mm to about 50 mm in length. In one embodiment, the rods are at least 20 mm in length. In one embodiment, the rods are at least 10 mm in length. In yet another embodiment, the rods are 50 mm or less in length.

[0162] In one embodiment, the rods are 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, and 40 mm in length.

[0163] 5C-5F are representative schematic diagrams of a parallax adjustment system in the main tube 210 of the observation optics according to one embodiment of the present disclosure. As shown in FIG. 5C, a device 530 such as a rod or shaft connects a focus cell (parallax lens) 535, which has been moved closer to the objective lens end of the observation optics, to a parallax cam track pin 540 in the parallax adjustment knob assembly. The shifted position of the parallax lens provides the necessary space for the prism lens in front of the first focal plane. One end of the connecting rod is coupled to the focus cell and the other end of the connecting rod is coupled to the cam pin.

[0164] 5D shows that device 530 connects focus cell 535 with a parallax lens to a parallax cam track pin 540 that rides on a cam track 545 of a parallax adjustment assembly 550. In one embodiment, parallax adjustment assembly 550 has a rotatable element to move the cam pin to adjust the parallax lens.

[0165] As shown in FIG. 5E, the focus cell is shifted closer to the objective lens assembly to provide space in the body of the observation optics for the beam combiner (prism lens). Therefore, a mechanism is needed to connect the focus cell to the parallax knob assembly. The connection device 530 connects the focus cell to a cam pin 540 that rides in a cam groove of the parallax knob assembly 560.

[0166] As shown in FIG. 5F, cam pin 540 rides in cam groove 545 of parallax knob assembly 560, allowing adjustment of the focus cell via the parallax knob assembly.

[0167] In one embodiment, a shifted focus cell in the body with a parallax lens provides space for integrating a beam combiner in front of the first focal plane of the objective lens system.

[0168] In one embodiment, the beam combiner within the body of the riflescope disclosed herein is positioned in the space where the focus cell would normally be mounted in a conventional riflescope.

[0169] In one embodiment, the present disclosure relates to an observation optical instrument comprising: (a) a main tube; (b) an objective lens system coupled to a first end of the main tube; (c) an eyepiece lens system coupled to a second end of the main tube; (d) a focus cell positioned between the objective lens system and a beam combiner, the beam combiner being positioned between the focus cell and a first focal plane reticle; and (e) a rod connecting the focus cell to a parallax adjustment element. In one embodiment, the rod connects the focus cell to a cam pin of the parallax adjustment element. In some embodiments, the parallax adjustment element has a knob.

[0170] 3. Magnification Tracking System In one embodiment, the present disclosure relates to a viewing optics and method for tracking the magnification setting of the viewing optics, where the components of the tracking mechanism are reliable, completely transparent to the operator, and protected from the environment.

[0171] When the reticle is in the first focal plane, it is in front of the erector system and therefore changes proportionately with the change in lens position, producing a magnified image. The erector system is repositioned using a magnification ring located on the outer part of the riflescope near the eyepiece housing. Typically, the magnification ring is threadedly connected to the outer erector sleeve, and turning the magnification ring rotates the outer erector sleeve with the magnification ring, and a cam groove changes the position of the zoom lens mounted on the erector system. When projecting a digital image into the first focal plane, it is necessary to scale this image with the scale of the reticle in order to make the digital image usable.

[0172] A magnification adjustment mechanism is coupled to a variable magnification or zoom lens element and provides the ability to adjust the optical magnification of an image of a distant object.

[0173] In one embodiment, and as shown in Figure 6, the potentiometer wiper 610 is positioned on the outer diameter of the outer upright sleeve 620. The potentiometer wiper contacts a membrane potentiometer 710 that is positioned on the inner diameter of the riflescope body 210 (see Figure 7).

[0174] As shown in Figure 8, in one embodiment, the potentiometer wiper 610 is a flat spring with two contact points to ensure that it maintains contact with the membrane potentiometer 710. The flat spring is positioned between the outer erection sleeve 620 and the inner erection tube. The potentiometer wiper 610 is positioned on the inner diameter of the riflescope, on the inner wall opposite the magnification ring slot threads 820. The potentiometer wiper 610 is secured to the inside side of the scope tube with an adhesive.

[0175] In one embodiment, the potentiometer wiper has the ability to lie completely flat on the outer diameter of the outer erect sleeve. In one embodiment, the potentiometer wiper is located inside the outer erect sleeve.

[0176] In one embodiment, the wiper of the potentiometer is not located on the magnification ring 810 of FIG.

[0177] The magnification tracking system disclosed herein is installed internally and no parts are exposed to the environment, which provides several advantages. First, the system is internal, so no seals are required to protect the wiper / erection system from the environment. Second, when theerection system is installed on the riflescope, the magnification tracking system is complete. This eliminates the possibility of debris entering the system through the threaded holes on the outside of the magnification ring.

[0178] In one embodiment, the present disclosure relates to a system for tracking magnification settings of a viewing optic that uses a sensor and materials with different optical reflectance / absorption, in one embodiment, the sensor is mounted to a base of the viewing optic, the base is coupled to a body of the viewing optic, and the materials are positioned in the body of the viewing optic.

[0179] In one embodiment, the present disclosure relates to a viewing optical instrument having a body with an erecting tube having an erecting lens system, a cam tube or sleeve surrounding or enclosing the erecting tube, materials with various optical reflectances / absorptions coupled to the cam tube, and a base coupled to the body, the base having an integrated display system and a photosensor for detecting optical reflection / absorption from the material. In one embodiment, the base has a printed circuit board or microprocessor for communicating with the photosensor and one or more microcontrollers or electronic controllers.

[0180] In one embodiment, the observation optical instrument has a body with a magnification adjustment ring for adjusting the optical magnification of the image, and a base coupled to the body and having an integrated display system, a microprocessor, and a system for communicating the magnification setting of the observation optical instrument to the microprocessor, the microprocessor in communication with the active display of the integrated display system.

[0181] In one embodiment, the present disclosure relates to a system for tracking the magnification setting of a viewing optic that has no mechanical link between the moving parts of the opto-mechanical system and the sensing device. The magnification tracking system disclosed herein is embedded in a base that is coupled to the body of the viewing optic and has no mechanical link between the stationary and moving parts of the system.

[0182] In one embodiment, the present disclosure relates to a viewing optical instrument having a body in which an erection tube houses an erection lens assembly, a cam sleeve surrounding the erection tube and having a material with varying optical reflectance / absorption, and a base coupled to the body, the base having a photosensor. In one embodiment, the material with varying optical reflectance / absorption surrounds the cam sleeve at an end of the cam sleeve near the magnification adjustment ring of the body. In one embodiment, the photosensor is positioned below the material with varying optical reflectance / absorption on the cam sleeve.

[0183] When the operator / user turns the magnification adjustment ring 212 of the viewing optics, the outer cam sleeve rotates and moves two lens cells, thereby changing the effective optical magnification of the riflescope.

[0184] In one embodiment, the cam sleeve comprises a material with varying optical absorptivity / reflectivity, which in one embodiment is applied to the outer diameter of the cam sleeve.

[0185] In one embodiment, the material is a strip of material. In one embodiment, the material is about 10 mm wide and about 40 mm long. In one embodiment, a first side of the material has an adhesive used to attach to the outer cam sleeve. In another embodiment, the other side of the strip has a grayscale gradient printed on it so that when an LED is pointed at it, a different amount of light is reflected depending on the portion of the gradient that is exposed to the LED.

[0186] In one embodiment, the PCB includes an LED and a photosensor. In one embodiment, the LED and photosensor are positioned under a tilted strip attached to the outer diameter of the outer cam sleeve. The LED illuminates the tilted strip and the photosensor can receive a portion of the light reflected from the tilted strip and send a signal to a microcontroller, where the strength of the signal changes with the amount of light detected.

[0187] As the operator turns the magnification adjustment ring, different portions of the tilt strip are exposed to the LED and photosensor, which in turn changes the signal strength it sends to the microcontroller. The optical magnification setting of the system can therefore be tracked by relating it to the amount of light detected by the photosensor.

[0188] Fig. 65 shows a side view of a 1-8x riflescope 6500 having a body 6502 and a base 6505 coupled to the body 6502. A magnification adjustment ring 6510 can be seen on the right side of the image.

[0189] FIG. 66 shows a side view of the riflescope 6500 with the body of the scope hidden to reveal the outer cam sleeve 6610 which rotates with the magnification adjustment ring 6510 to change the magnification setting.

[0190] Figure 67 shows the base 6505 of the viewing optics 6500 with a printed circuit board 6710 containing a photosensor and LED 6720 used to measure the position of a reflective graded material attached to the outer cam sleeve of the body. The outer cam sleeve and associated optics are hidden in this image.

[0191] FIG. 68 is a representative exploded view of the photosensors and LEDs on a printed circuit board 6710, with a simulated viewing cone drawn to illustrate the light acceptance angle for the photosensors.

[0192] 69 and 70 are images of a photosensor and LED 6720 in conjunction with a reflective tilt strip 6910 attached to an outer cam sleeve 6610 to measure the magnification setting of the viewing optics. Note that this shows the tilt strip 6910 with four specific compartments of different reflectivity, but the strip can vary infinitely in reflectivity. The tilt strip 6910 is coupled to the cam sleeve at a portion of the cam sleeve that is positioned near the magnification adjustment ring. The printed circuit board 6710 is positioned in a base 6505 that mates with the body of the viewing optics. The LED and photosensor 6720 on the printed circuit board 6710 are positioned below the tilt strip 6910.

[0193] In one embodiment, the present disclosure provides a microscope comprising: a body having a central axis with a first end and a second end; an objective lens system disposed within the body; an eyepiece disposed within the body; an erection tube disposed within the body and having an erection lens system, the objective lens system, the eyepiece and the erection lens system forming an optical system having a first focal plane and a second focal plane, the first focal plane being proximate to the objective lens system and the second focal plane being proximate to the eyepiece; a cam sleeve surrounding the erection tube that moves in cooperation with a magnification adjustment ring to adjust the optical magnification of the image, the cam sleeve having materials with different optical absorptance / reflectance bonded to the cam sleeve; The present invention relates to an observation optics comprising: a base having a photosensor coupled to the body for detecting light from a material, a microprocessor in communication with the photosensor, and an active display in communication with the microprocessor, for generating an image based on a magnification setting and projecting the generated image onto a first focal plane of the observation optics. In one embodiment, the image generated from the active display is based on a signal obtained from the photosensor.

[0194] Communicating the magnification setting to a microprocessor has many advantages, including, but not limited to, modifying the reticle pattern based on the magnification setting and automatically changing the font size of alphanumeric information in response to changes in magnification. Additionally, if multiple display "pages" are stored in the memory system, the microcontroller can automatically switch between "display" pages depending on the magnification setting in order to present the most relevant data to the operator.

[0195] 4. Additional Components In one embodiment, the viewing optics can be controlled by buttons integral to the riflescope or by externally mounted buttons.

[0196] In one embodiment, the body of the viewing optics can include a camera system.

[0197] In one embodiment, the body of the observation optics can include one or more computing systems.

The processor may control the operation of the display system and / or reticle. The processor may also receive inputs from a user interface, data inputs, memory, sensor(s), position encoders associated with the position of an adjustable component (e.g., vertical adjustment knob, windage adjustment knob, or parallax dial), and / or from other sources.

In yet another embodiment, the length of the base with the integrated viewing system is 40% to 65% of the length of the body of the riflescope to which the base is coupled. In yet another embodiment, the length of the base with the integrated viewing system is 65% or less of the length of the body of the riflescope to which the base is coupled.

[0209] In one embodiment, the body of the riflescope is approximately 2.5 times the length of the base with the integrated viewing system. In yet another embodiment, the body of the riflescope is 1.5 to 2.5 times the length of the base with the integrated viewing system. In yet another embodiment, the body of the riflescope is at least 1.5 times the length of the base with the integrated viewing system.

[0210] 2, the base 220 can be bolted to the scope body 210 of a riflescope to form a completely sealed and integrated system, in which case the base 220 can be attached directly to the firearm without the need for traditional riflescope rings.

[0211] Figure 10 shows a top view of the riflescope 200 with the body 210 and the base 220. Figure 10 clearly shows that the base 220 ensures that the riflescope does not protrude in any position or become out of proportion with a conventional riflescope. The riflescope disclosed herein with its body and base maintains the traditional and sleek design of a riflescope.

[0212] 11 shows the base 220 attached to the riflescope body 210. The base 220 is aligned and flush with the outer edge of the body 210.

[0213] 2, a base with an integrated display system is coupled to the bottom side of riflescope body 210, with one end of the base coupling near the magnification selection ring or ring 212 of body 210 and the other end of the base coupling near the beginning of objective lens assembly 214 of the body. In one embodiment, base 220 is coupled to body 210 by threaded fasteners, non-threaded integral and non-integral locating and recoil transfer features, and elastomeric seals.

[0214] In one embodiment, the base can be compartmentalized with the components necessary to generate the digital display and then the base can be bolted to the body of the riflescope to form a completely sealed and integrated system.

[0215] In one embodiment, the base and the body of the scope are a sealed, integrated system. In one embodiment, the base is coupled to the body without the use of clamps designed for easy removal.

[0216] In one embodiment, a viewing optic having a body and a base coupled to the body can be coupled to a firearm without the need for traditional rifle scope rings. In one embodiment, the viewing optic has a body and a base coupled to the body, with a bottom side of the base having a mounting rail.

[0217] In one embodiment, the base of the observation optic can include a mounting rail for attachment to a desired firearm, instrument, or device, and can have an adjustment mechanism including an elevation adjustment drum for adjusting the elevation position of the optic. Lateral adjustment mechanisms are also typically provided for lateral adjustment. These adjustment mechanisms can be covered with a protective cap.

[0218] In one embodiment, the upper side of the base is coupled to a bottom side of the body of the observation optics, and the bottom side of the base has a mounting rail. In one embodiment, the upper side of the base is coupled to a lateral division of the bottom side of the body of the observation optics.

[0219] In one embodiment, the base includes an integrated display system for generating an image using an active display and directing the generated image along a display optical axis so that the generated image can be viewed simultaneously and superimposed with an image of the external scene, and the generated image is introduced into a first focal plane of the body of the observation optics.

[0220] In one embodiment, the base is separate and distinct from the laser range finder device. In one embodiment, the base is a separate device from the laser range finder device.

[0221] In one embodiment, the second housing or base is not an add-on accessory. In another embodiment, the second housing or base is not coupled with an adapter as an add-on accessory adjacent to the eyepiece of the viewing optics.

[0222] In one embodiment, the second housing or base cannot be separated from the main body by an end user. In an embodiment, the second housing or base cannot be replaced with multiple or other viewing optics.

[0223] In one embodiment, the present disclosure relates to a system including an observation optical instrument having a body with a first optical system and a base coupled to the body and having a second optical system, such as an integrated display system, and a laser range finder device.

[0224] 1. Integrated Display System In one embodiment, the second housing includes the integrated display system. In another embodiment, the base includes the integrated display system. In yet another embodiment, the base with the integrated display system is coupled to the body of the riflescope. In yet another embodiment, the base is coupled to the bottom of the body of the riflescope.

[0225] In one embodiment, the base has an integrated display system comprising an active display, concentrator optics, 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 concentrator optics, followed by a reflective material such as a mirror.

[0226] 12 is a top cutaway view of a base 220 coupled to the body of the viewing optics. The base 220 includes an integrated display system having a microdisplay 1210, concentrator optics 1220, and a mirror 1230. In one embodiment, the mirror 1230 can be positioned at any suitable angle.

[0227] 13 is a cutaway side view of base 220 with an integrated display system having a microdisplay 1210, concentrator optics 1220, and a mirror 1230. Body 210 has a beam combiner 320 positioned above mirror 1230.

[0228] 14 shows a cutaway side view of a riflescope having a body 210 and a separable base 220. The base 220 includes a microdisplay 1210, concentrator optics 1220, and a mirror 1230. The mirror 1230 is positioned at approximately 45 degrees. The scope body 210 has a beam combiner 320 positioned approximately above the angled mirror 1230. The beam combiner 320 is positioned approximately below the elevation adjustment knob 1410 of the scope body 210. The active display 1210 is positioned within the base on the eyepiece assembly side 1420 when the base 220 is coupled to the viewing optics body 210.

[0229] 15, the image generated from the microdisplay 1210 can be redirected from the display optical axis A to the observation optical axis A via mirror 1230 to the beam combiner 320 in the body 210 such that the digital image is simultaneously superimposed or overlapped in a first focal plane 1510 onto an image of the scene observed by the observer through the optics. Because the beam combiner 320 is positioned in front of the first focal plane 1510 and the combined image is focused in the first focal plane, the displayed image and the observed image do not move relative to each other. This is a significant improvement over devices that introduce an image in a second focal plane.

[0230] In one embodiment, the active display 1210 is located in a portion of the base closest to the objective lens assembly 214 compared to the eyepiece lens assembly of the riflescope body when the base is coupled to the riflescope body, as shown in Figure 16. The riflescope body has an analog reticle 1610.

[0231] Figure 17 shows a riflescope 200 with a body 210 with a beam combiner 320 and a base 220 coupled to the body and having an integrated display system. As shown in Figure 17, the active display 1210 is located in a portion of the base that is closest to the eyepiece assembly compared to the objective lens assembly of the riflescope body when the base is coupled to the riflescope body. By superimposing the image from the integrated display system on the first focal plane, the user can still use a conventional glass-etched reticle 1610 for aiming purposes.

[0232] In one embodiment, the integrated display system can direct a generated image from the active display along a display optical axis A. The generated image can be directed from the display optical axis A to a mirror in the base and to a beam combiner in the body of the riflescope such that the generated image is simultaneously superimposed or overlapped on an image of a scene viewed by an observer through the optics of the body, where the combined image is introduced or focused at a first focal plane of the optics of the body.

[0233] In one embodiment, the image generated from the active display in the base is focused on a first focal plane of the riflescope body, thereby allowing the image generated from the display to maintain alignment with externally mounted equipment.

[0234] In one embodiment, the image generated from the active display in the base is focused on a first focal plane of the body of the riflescope, so that the image generated is not bound to the movement of the erection tube. The image generated is independent of the movement of the erection tube.

[0235] In one embodiment, light from the active microdisplay is collected by an optical lens group. The light from the display is reflected to a beam combiner in the riflescope main tube assembly to form a display image that is coincident with the first focal plane of the riflescope. This display image is combined with the scene (target) image and is perceived as being "below" the surface of a traditional wire or glass-etched reticle. In one embodiment, the "traditional" reticle, which is still utilized, occludes both the scene image and the display image. When the display brightness is increased to a sufficient brightness level, the OLED display image will fill the scene image and appear to occlude the scene as well.

[0236] In yet another embodiment, an integrated display system in the base can direct the generated image along a display optical axis "B" onto an observation optical axis A in the body of the riflescope. The generated image can be redirected from the display optical axis B with a mirror or similar reflective material in the base towards the observation optical axis A in the body to a beam combiner in the body, allowing the generated image to be simultaneously superimposed or overlapped onto an image of the scene viewed by an observer through the optics of the body. The generated image from the active display in the base is directed to a mirror, which reflects the generated image to the beam combiner.

[0237] In one embodiment, the display optical axis "B" and the viewing optical axis "A" are substantially parallel, but in alternative embodiments may be oriented differently as desired.

[0238] A. Active Display In one embodiment, the integrated display system has an active display. In one embodiment, the active display is controlled by a microcontroller or computer. In one embodiment, the active display is controlled by a microcontroller with an integrated graphics controller for outputting video signals to the display. In one embodiment, information can be transmitted wirelessly or by physical connection into the viewing optics via a cable port. In yet another embodiment, multiple input sources can be input into the microcontroller and displayed on the active display.

[0239] In one embodiment, the active display and the beam combiner are not located in the same housing. In one embodiment, the active display and the beam combiner are located in separate housings.

[0240] In one embodiment, the active display may be a reflective, transmissive or emissive microdisplay, including, but not limited to, a microdisplay, a transmissive active matrix LCD display (AMLCD), an organic light emitting diode (OLED) display, a light emitting diode (LED) display, an electronic ink display, a plasma display, a segmented display, an electroluminescent display, a surface conduction electron emission display, a quantum dot display, and the like.

[0241] In one embodiment, the LED array is a micro-pixelated LED array, and the LED elements are micro-pixelated LEDs (also referred to herein as micro-LEDs or μLEDs) having a small pixel size of generally 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 (in both the vertical and horizontal directions of the micro-LED array) ranging from about 10 μm to about 30 μm. In one embodiment, the micro-LED elements have a uniform pixel size of about 14 μm (e.g., all micro-LED elements are the same size within a small tolerance) and are arranged in the micro-LED array with a uniform pixel pitch of about 25 μm. In some embodiments, the LED elements may each have a pixel size of about 25 μm or less, and a pixel pitch of about 30 μm or less.

[0242] In some embodiments, microLEDs are inorganic and may be based on gallium nitride light emitting diodes (GaN LEDs). MicroLED arrays (comprising many μLEDs arranged in a grid or other arrangement) may provide high density, emissive microdisplays that are not based on external switching or filtering systems. In some embodiments, GaN-based microLED arrays may be grown, bonded, or otherwise formed on a transparent sapphire substrate.

[0243] In one embodiment, the sapphire substrate is textured, etched, or otherwise patterned to enhance the internal quantum efficiency and light extraction efficiency of the micro-LEDs (i.e., extract more light from the surface of the micro-LEDs). In another embodiment, silver nanoparticles can be deposited / dispersed onto the patterned sapphire substrate to coat the substrate before bonding the micro-LEDs to further enhance the light efficiency and output power of GaN-based micro-LEDs and micro-LED arrays.

[0244] In one embodiment, the active display may be monochrome, or may provide full color, and in some embodiments may provide multiple colors. In other embodiments, other suitable designs or types of displays may be employed. The active display may be driven by electronics. In one embodiment, the electronics may provide the display functionality, or may receive such functionality from another device in communication with the electronics.

[0245] In one embodiment, the active display can be part of a backlight / display assembly, module or configuration having a backlight assembly including a backlight illumination 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 lens or an integrated lens for collecting and directing the generated light to a second illumination or focusing lens to focus the light onto the active display with good spatial and angular uniformity and direct it along the display optical axis B. The backlight assembly and active display can provide an image that is low power yet bright enough to be viewed simultaneously with a very bright real world view through optical instruments.

[0246] The backlight color can be chosen to be any monochrome, or can be white to support full-color microdisplays. Other backlight design elements, such as other light sources, waveguides, diffusers, micro-optical elements, polarizers, birefringent components, optical coatings and reflectors, can be included to optimize the performance of the backlight, compatible with the overall size requirements of the active display, as well as the brightness, power and contrast needs.

[0247] 16 and 17 depict a representative example of an integrated display system in a base that mates with the body, showing the display, optics, and mirrors, which works with the optics housed in the body of the viewing optics depicted above.

[0248] Representative examples of microdisplays that can be used include, but are not limited to, those manufactured by Microoled, including MDP01 (series) DPYM, MDP02, and MDP05; those manufactured by Emagin, such as SVGA, microdisplays with pixel pitches of 9.9x9.9 μm and 7.8x7.8 μm; and those manufactured by Kopin Corporation, such as the Lightning Oled Microdisplay. MicroLED displays, including, but not limited to, those manufactured by VueReal and Lumiode, can also be used.

[0249] In one embodiment, the electronics cooperating with the active display may include capabilities for generating display symbols, formatting output to the display, and may include battery information, power conditioning circuitry, video interfaces, serial interfaces, and control features. Other features may be included for additional or different functionality of the overlay display unit. The electronics may provide the display functionality or may receive such functionality from another device in communication with the electronics.

[0250] In one embodiment, the active display generates imagery including, but not limited to, text, alphanumeric characters, graphics, symbols, and / or video capture, icons, etc., including active target reticles, range measurements and wind information, GPS and compass information, firearm tilt information, target detection, recognition and identification (ID) information, and / or external sensor information (sensor video and / or graphics), or imagery for situational awareness, etc., that can be viewed through the eyepiece along with an image of the field of view seen through the optics. The direct viewing optics can include or maintain an etched reticle and muzzle sight and retain high resolution.

[0251] In one embodiment, the active display can be used to display a programmable electronic aim point at any location within the field of view. This location can be determined by the user (as in the case of rifles that fire both supersonic and subsonic bullets and therefore have two different ballistic trajectories and "zero-ins") or can be calculated based on information received from a ballistic calculator. This provides a "drop-compensated" aim point for long-range shooting that can be updated at shot-by-shot intervals.

[0252] In one embodiment, the active display may be oriented to provide maximum vertical correction, hi one embodiment, the active display is positioned so that it is taller than it is wide.

[0253] In one embodiment, the active display is oriented as shown in Figure 18, which allows for the maximum vertical adjustment range 1810 for the active reticle within the riflescope. Maximum vertical adjustment is advantageous because it allows for ballistic correction in longer range scenarios.

[0254] In one embodiment, the integrated display system further comprises a processor in electronic communication with the active display.

[0255] In another embodiment, the integrated display system may include an electronic communication device in electronic communication with the memory, at least one sensor, and / or the processor.

[0256] Distance measurement usage In one embodiment, the active display can display distance measurements obtained from a laser range finder. In one embodiment, the LRF can be coupled to the viewing optics. In one embodiment, the LRF is directly coupled to an outer scope body of the riflescope. In another embodiment, a portion of the LRF is directly coupled to an outer portion of the scope body of the riflescope.

[0257] In one embodiment, the LRF is indirectly coupled to an outer scope body of the riflescope. In another embodiment, a portion of the LRF is indirectly coupled to an outer portion of the scope body of the riflescope.

[0258] In yet another embodiment, the LRF is not coupled to the riflescope, but communicates with the riflescope either via hard wiring or wirelessly.

[0259] In general operation, the LRF provides a pulse of laser light that is projected onto a scene via projection optics. This laser light illuminates an object and a portion of the laser light is reflected back to the LRF. The portion of the reflected laser light that returns to the device is captured by receiving optics and directed to a detector. The device includes a timer that starts when the laser light pulse is sent out and stops when the returning laser light is detected. The computer portion of the device uses the elapsed time between sending out the laser light pulse and detecting the returning reflected laser light to calculate the distance to the object.

[0260] In one embodiment, the distance calculations are sent to an active display and the generated image (distance measurement or calculation) is redirected using mirrors and beam combiners from the display optical axis "B" onto the viewing optical axis A so as to simultaneously superimpose or overlap the image (distance measurement or calculation) onto the image of the scene viewed by the viewer through the viewing optics.

[0261] Windage Range Bar In another embodiment, the active display can generate a windage range. In one embodiment, a user can provide a range of wind values ​​and the software can generate the windage data, e.g., a windage range variation bar. In one embodiment, the windage data is sent to the active display and the generated image, e.g., a windage range variation bar, is redirected using mirrors and beam combiners from the display optical axis "B" onto the viewing optical axis "A" so that the image (windage range variation bar) is simultaneously superimposed or overlaid onto the image of the scene viewed by the viewer through the viewing optics.

[0262] In one embodiment, the windage data includes a minimum windhold point to a maximum windhold point.

[0263] In one embodiment, the windage data is sent to an active display, which can generate a digital reticle within the field of view at the appropriate windhold.

[0264] Colors for Mental Cues In one embodiment, the active display can generate a color display to convey an extra level of information to the user in a quickly understandable format, hi one embodiment, the active display can generate a series of color-coded symbols to indicate a ready to launch state.

[0265] In one embodiment, the active display can generate a series of color-coded symbols to color-code objects in a target scene. In one embodiment, the active display can color-code friendly forces from hostile forces. In another embodiment, the active display can color-code targets of interest.

[0266] In one embodiment, the active display can generate a series of color coded symbols to indicate the windage adjustment status. In one embodiment, a red dot can indicate that the windage adjustment is not complete, while a green symbol can indicate that the windage adjustment is complete.

[0267] In another embodiment, the active display can generate a colored aim point. In one embodiment, if proper adjustments have not been made, including but not limited to windage, range, and elevation, the aim point is red. In another embodiment, if some, but not all, fire adjustments have been completed, the aim point is yellow. In yet another embodiment, if all necessary fire adjustments have been completed, the aim point is green and the aim point is fully corrected.

[0268] In yet another embodiment, the flashing and solid state of the symbol may be utilized to convey similar status information regarding the adjustment of the aimpoint.

[0269] In yet another embodiment, the active display can generate text that is colored to indicate a status. In one embodiment, red text indicates that input parameters have not been entered or calculated, and green for the text indicates parameters that have been entered or calculated.

[0270] Markers for impact zones in range finding In one embodiment, the active display can generate a circle, square, or other shape to allow a user to quickly capture or encircle the impact zone of a projectile.

[0271] Holdover Estimation and Correction In another embodiment, the active display can generate a compensated aim point for a moving target based on user input for direction and speed of movement. For example, a user can input a speed of movement left of 5 miles per hour, which will be added to the windage value if the wind and movement are in the same direction and subtracted from the windage value if the wind and movement are in the opposite direction. In this case, when the aim point and / or windage value bar are plotted on the display, the aim point will include an appropriate amount of holdover, allowing the user to place the aim point dot at the desired impact zone and shoot, rather than having to place the aim point in front of the moving target to compensate for the target's movement.

[0272] Team operations using cameras and remote display operations In one embodiment, an active display in conjunction with a network interface allows an additional level of enhanced operation and use. In one embodiment, multiple shooters' reticle images are viewable over the network. Each shooter's reticle camera image is displayed on one or more consoles, and the network processes and interfaces allow for group-level coordination, training, and collaboration not previously available with individual riflescopes.

[0273] Training and Guidance In a training or instruction scenario, the instructor can see how each shooter aligned their reticle on their target. The ability to actually see the reticle alignment allows the instructor or trainer to provide instructions regarding adjustments and repositioning, such as by verbal instructions (e.g., over the radio or in person).

[0274] In another embodiment, the instructor's console may be provided with a pointing means, such as a mouse or joystick, for which control data is transferred from the console over a network to the rifle's integrated display system. The instructor's mouse or joystick then controls an additional dot or pointer in the display of each shooter's scope, allowing the instructor to visually show the shooter which target to use, which distance marker bar to use, and where to position the reticle relative to the target. In one embodiment, each shooter may be given their own unique instructor dot, allowing the instructor to give each shooter individualized instructions.

[0275] Firing Adjustment In another embodiment, the active display can be used in the coordination and execution of a multi-shooter firing team. In one embodiment, a team leader operates the leader console and uses the leader dots to assist with target assignments to each shooter, communicating reticle placement changes, etc.

[0276] Snapshots for remote review and approval In another embodiment, the active display and network process allows a shooter, given control, 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 this image is received by a director or instructor, the director or instructor reviews the image and approves or disapproves the shot. For example, in a teaching scenario, a user can take a snapshot of an animal that they believe is a legitimate animal (age, species, sex, etc.) to be shot. If the instructor agrees, he or she can indicate this by positioning or moving an instructor dot in the shooter's reticle.

[0277] Biometric classification of targets In another embodiment, the snapshot of the reticle image is received by a biometric recognition and / or classification process, such as a facial recognition system. The biometric recognition and / or classification process may be on-board the gun, such as integrated into the display control logic, or may be remote from the gun and interconnected via a network. The results of the recognition and / or classification process may be provided to the reticle by transmitting the results over the network to the control logic and updating the display accordingly.

[0278] Side-by-side image display In another embodiment, an image is downloaded to the integrated display system over a network and displayed simultaneously with the observed image of the target in the reticle. The downloaded image allows the user (shooter) to perform a side-by-side comparison of the currently observed target with a previously captured image or photograph of a target similar to the one he has been instructed or wishes to photograph. For example, during doe season, a novice shooter may be provided with a reference image of a doe in the reticle to compare in real time with the actual animal he views through the scope. In a military or law enforcement application, an image of a sought enemy or fugitive may be displayed in the reticle for real-time comparison with the face of the person the shooter is viewing through the scope.

[0279] A typical example of an active display a.530~570nm In one embodiment, the present disclosure relates to an integrated display system using 530-570 nm microdisplays.

[0280] FIG. 19 shows an integrated display system with a 530-570 nm digital display 1910.

[0281] Figure 20 is a schematic diagram of an exemplary image 2020 that can be displayed on a 530-570 nm digital display 1910. As shown in Figure 20, a glass etched reticle 2010 can be used with the devices and systems disclosed herein. These images are exemplary only and should not be construed as limiting the amount or type of information that can be displayed on an active display.

[0282] In another embodiment, the incorporation of a 530-570 nm digital display 1910 allows for relatively higher effectiveness than any other color display due to the sensitivity of the human eye, which allows for less power consumption compared to powering a red or blue display of the same photometric brightness.

[0283] In yet another embodiment, the incorporation of a 530-570 nm digital display 1910 gives the end user greater ability to distinguish the digital overlay from the background created by ambient light with daylight vision.

[0284] b. AMOLED In one embodiment, the present disclosure relates to an integrated display system that includes an AMOLED microdisplay.

[0285] FIG. 21 shows an integrated display system with an AMOLED digital display 2110.

[0286] Figure 22 is a schematic diagram of an example image 2210 that can be displayed on an AMOLED digital display. As shown in Figure 22, a glass etched reticle 2010 can be used with the devices and systems disclosed herein. These images are merely exemplary and should not be construed as limiting the amount or type of information that can be displayed on an active display.

[0287] In one embodiment, the image generated by the AMOLED 2110 is integrated / imaged / focused onto 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 on the riflescope.

[0288] In one embodiment, the incorporation of an AMOLED display 2110 allows for selection of individual pixels that are illuminated, giving the riflescope the ability to easily display complex data configurations.

[0289] In another embodiment, the incorporation of an AMOLED display 2110 allows for a small, lightweight package size inside the riflescope due to a reduced need for backlighting in the system.

[0290] In another embodiment, the integrated display system does not require a backlit display assembly.

[0291] In yet another embodiment, the incorporation of the AMOLED display 2110 allows for reduced power consumption since the ability to optimize power usage for individual pixels is now available.

[0292] In one embodiment, the incorporation of an AMOLED display 2110 provides contrast ratios that allow for a clean "heads-up" style display within the scope. The contrast ratios allow each floating feature to be individually targeted and rendered without low glow around the pixels.

[0293] B. Condenser lens system In one embodiment, the integrated display system has an optical system based on the use of optical lenses as part of one or more lens cells, the lens cells including the lenses themselves and the lens cell body in which the lenses are mounted. In one embodiment, the lens cell includes a roughly cylindrical or disc-shaped precision formed body having a central aperture for mounting the lens in alignment with the optical axis of the larger optical system. The cell body can also be said to have its own alignment axis, which will ultimately be aligned with the optical axis of the larger optical system when the lens cell is mounted therein. Additionally, the lens cell acts as a "holder" for the lens, a mechanism by which the lens can be mounted to and within the larger optical system, and (eventually) a means by which the lens can be manipulated by that optical system for its purposes.

[0294] In one embodiment, the integrated display system comprises a concentrator lens system, also referred to as a lens system, hi one embodiment, the concentrator lens system comprises an inner lens cell and an outer lens cell.

[0295] FIG. 23 is a representative example of a concentrator lens system 2310 having an inner lens cell 2315 and an outer lens cell 2320. In one embodiment, the outer lens cell 2320 houses at least one lens and the inner lens cell 2315 houses at least one lens. In one embodiment, the inner lens cell 2315 rotates on the inner surface of the outer lens cell 2320. As shown in FIG. 23, the active display 1210 is bonded to a flat textured surface on the back of the inner lens cell 2315. In one embodiment, the active display 1210 can be directly bonded to the inner lens cell 2315. In yet another embodiment, the active display 1210 can be indirectly bonded to the inner lens cell 2315.

[0296] One advantage of the concentrator optics disclosed herein is that the inner lens cell coupled to the microdisplay mount provides a rigid rotating mechanical axis for positioning the vertical axis of the microdisplay.

[0297] 24 is a representative illustration of a base 220 mating with a viewing optics body, where the base has a concentrator optic 2310 as part of an integrated display system. In FIG. 24, the body is depicted with a beam combiner 320 and a viewing optics reticle 2420.

[0298] The outer lens cell 2320 is fixed in position within its body relative to the viewing optics, while the inner lens cell 2315 is allowed to rotatably float within the outer lens cell 2320. By applying pressure to a surface 2410 of the inner lens cell 2315 that is positioned below the axis of rotation of the inner lens cell 2315, the vertical axis of the active display 1210 can be aligned with the vertical axis of the reticle 1610 of the viewing optics.

[0299] FIG. 25 is a representative illustration of one embodiment for aligning the tilt of the vertical axis of the active display with the vertical axis of the reticle. As shown in FIG. 25, opposing set screws 2505 can be tightened against a surface of the inner lens cell 2315 that is located below the axis of rotation of the inner lens cell 2315. The set screws 2505 can be used to align the vertical axis of the microdisplay 1210 with the vertical axis of a reticle in the optical system within the body of the viewing optics. The rotation of the inner lens cell 2315 can be maintained by securely tightening the set screws 2505 against the lower surface of the inner lens cell 2315, thereby locking the vertical axis of the microdisplay 1210 in place.

[0300] 26 is a representative diagram of a rear cutaway view of the condenser lens system 2300 with tilt adjustment of the microdisplay 1210 or active display. When the microdisplay is introduced into the observation optics using a beam combiner or a waveguide, an additional correction method is required to remove the tilt error between the reticle vertical axis and the introduced image of the microdisplay vertical axis. A set screw 2505 is tightened against the surface of the inner lens cell 2315 located below the rotation axis of the inner lens cell 2315, thereby aligning the microdisplay 1210 vertical axis with the reticle vertical axis in the optical system inside the body of the observation optics.

[0301] FIG. 27 is a representative diagram of a method and apparatus for eliminating parallax between a microdisplay and a reticle in the optical system of the main body of a viewing optics. An outer lens cell 2320 houses at least one lens on the right side of FIG. 27, and an inner lens cell 2315 houses at least one lens on the left side of FIG. 27. The inner lens cell 2315 slides along the optical axis on the inner surface of the outer lens cell 2320. The microdisplay 1210 is coupled to the inner lens cell 2315. A spring 2710 is placed between the outer lens cell 2320 and the inner lens cell 2315 to separate the cells when not under compression.

[0302] 28A is an exemplary illustration of a base having collector optics 2300 and coupled to a viewing optics body. In FIG. 28A, the body is depicted with a beam combiner 320 and a viewing optics reticle 2810.

[0303] The outer lens cell 2320 is fixed in position relative to the viewing optics, and the inner lens cell 2315 is allowed to float inside the outer lens cell 2320. By forcing the inner lens cell 2315 forward with a screw or wedge 2820 that applies force to the back of the inner lens cell / active display mount, the axial position of the microdisplay image is changed so that its focal plane is positioned flush with the viewing optics reticle in the body of the viewing optics, thus eliminating parallax between the microdisplay and the reticle.

[0304] The position of the inner lens cell is kept in place by the action of a spring pushing a screw or wedge outward. Parallax between the active display and the reticle can be eliminated without changing the amount of focus from the active display and without degrading the image quality of the optical system.

[0305] The use of springs between the inner and outer lens cells and the application of force to the back surface of the inner lens cell / microdisplay allows the maximum amount of light to be collected from the microdisplay and provides a quick, simple and accurate method of adjustment.

[0306] In one embodiment, the inner lens cell 2315 and the outer lens cell 2320 can comprise two or more lenses. In yet another embodiment, the lens system can comprise three, four, five, six, seven, eight, nine, ten, eleven or more lenses. Lenses are available from a variety of commercial manufacturers, including, but not limited to, LaCroix Optics (www.lacroixoptics.com) and Diverse Optics (www.diverseoptics.com). In one embodiment, the inner lens cell and the outer lens cell comprise a concentrator lens system.

[0307] In one embodiment, the lens system is comprised of a five-lens system. In one embodiment, the five-lens system is comprised of five single lenses. In another embodiment, the five-lens system is comprised of two doublet lenses and one single lens. In yet another embodiment, the five-lens system is comprised of three single lenses and one doublet lens. In one embodiment, at least one plastic aspheric lens is used as the first element.

[0308] In one embodiment, the lens system is a five-lens system with the following order: an aspheric singlet closest to the active display, then a singlet, then a doublet, then the last singlet.

[0309] In one embodiment, the lens system is a five-lens system with the following order: an aspheric singlet closest to the active display, then a singlet, then a singlet, then a doublet.

[0310] In one embodiment, the lens system is a five-lens system with the following order: the aspheric singlet closest to the active display, then a singlet, then a singlet, then a doublet. In one embodiment, the lens system is a five-lens system with the following configuration: Lens 1 closest to the active display is 11 mm in diameter and 9.3 mm thick, Lens 2 is 9 mm in diameter and 1.9 mm thick, the doublet has one lens (Lens 3) that is 13.5 mm in diameter and 2.1 mm thick, another lens (Lens 4) that is 13.5 mm in diameter and 4.1 mm thick, and Lens 5 is 13.5 mm in diameter and 3.3 mm thick.

[0311] In one embodiment, the air spacing from one lens to the next ranges from about 1 mm to about 20 mm. In one embodiment, the air spacing from one lens to the next ranges from about 5 mm to about 20 mm. In one embodiment, the air spacing from one lens to the next ranges from about 10 mm to about 20 mm.

[0312] In one embodiment, the distance between the active display and the first lens is minimized 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.

[0313] In one embodiment, the 5-lens system is housed in an inner lens cell and an outer lens cell. In one embodiment, the inner lens cell is assembled by placing an aspheric lens, then a spacer, then lens 2 (which can be a 9mm single lens), and then a locking ring (which holds both lenses in place) into the inner lens cell from the opposite end of where the display pedestal is.

[0314] In one embodiment, the outer lens cell is assembled by inserting lens 5 (which may be a 13.5 mm singlet lens), then a spacer, then doublet lens 2 (which may be lenses 3 and 4), and then a locking ring into the outer lens cell from opposite ends of the cell.

[0315] 28B is a representative illustration of a base with a concentrator optic or lens system. The inner lens cell 2315 is assembled by placing an aspheric lens 2840, then a spacer, then a glass concave-convex lens 2850 into the inner lens cell from the opposite end where the display pedestal is. In one embodiment, the glass concave-convex lens can be Lens 2 as described above. The outer lens cell 2320 can be assembled by inserting a glass doublet 2860 followed by a glass singlet 2870.

[0316] In one embodiment, the concentrator lens system comprises a five lens system including 2840, 2850, 2860, and 2870, with 2840 closest to the active display and 2870 furthest from the active display. In one embodiment, the inner lens cell 2315 comprises 2840 and 2850. In one embodiment, the outer lens cell 2320 comprises 2860 and 2870.

[0317] In one embodiment, axial movement of the inner lens cell along the inner diameter of the outer lens cell changes the spacing between lens 2 of the inner cell and lens 3 of the outer cell. This is used to move the focal plane of the display image and completely eliminate parallax between the projected display image and the passive reticle in the body of the viewing optics.

[0318] In one embodiment, focusing the display image onto a first focal plane of an optical system within the body is achieved by changing the air spacing between lenses 2 and 3 of a five-lens system, which is achieved by changing the position of the inner lens cell relative to the outer lens cell.

[0319] In one embodiment, the lens assembly can also be assembled together in a lens barrel, which is a one-piece mechanical structure that holds a series of lenses. The lens barrel is used to position the lenses axially and radially relative to each other, as well as to provide a means to align the lens assembly with the optical system of which it is a part. The lens elements are positioned radially by the inner diameter or ID of the barrel wall. The outer diameter or OD of the lens elements is ground to match the ID of the barrel wall. The axial location of the lens elements is achieved by cutting the lens seat during assembly. The lens elements can then be constrained to the lens seat with epoxy, a retaining ring, or the like.

[0320] C. Reflective material In one embodiment, the integrated display system comprises a reflective material 1230. In one embodiment, the reflective material 1230 is a mirror. In one embodiment, the integrated display system comprises one or more mirrors. In one embodiment, the integrated display system comprises two, three, four, five or more mirrors.

[0321] 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 display emission light.

[0322] 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 display emission light.

[0323] 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° to the display emission light.

[0324] In one embodiment, and as shown in Figure 29, the tilt of the mirror 2910 along the vertical axis can be adjusted using a screw or similar mechanism. By turning the screw into the base or back of the mirror 2910, the angle at which the microdisplay image is reflected into the beam combiner can be changed. This correspondingly changes the tilt of the focal plane at the viewing optics reticle 2930 of the viewing optics body optics. This adjustment can be used to eliminate parallax error of the microdisplay and reticle along the vertical axis.

[0325] In one embodiment, the mirror is secured to the base by one or more screws, hi one embodiment, the mirror is secured to the base using a compound such as an epoxy, resin, or adhesive, or a combination thereof.

[0326] In one embodiment, the position of the mirror can be adjusted relative to the beam combiner to eliminate errors including, but not limited to, parallax errors.

[0327] In one embodiment, the position of the mirror can be adjusted relative to the active display to eliminate errors including, but not limited to, parallax errors.

[0328] 2. Power System In one embodiment, a base that mates with the body of the observation optics includes the power system. In another embodiment, the base of the observation optics includes a cavity. A battery cavity can be incorporated into the base that mates with the body of the observation optics.

[0329] Figure 30 is a representative schematic diagram of a base 220 with a battery compartment 3005, where the base 220 is coupled to the body 210 of a riflescope 3000. As shown in Figures 30 and 31, the battery compartment 3005 extends from each side of the base to receive a battery, including a CR123 battery, which has increased power capacity and discharge capacity compared to smaller batteries or coin cells.

[0330] In one embodiment, the battery cavity 3005 is integral with the base 220 such that only a battery cap is needed to protect the battery from the environment. No additional sealing is required.

[0331] In one embodiment, the battery cavity 3005 in the base 220 is positioned closer to the objective lens assembly 3010 than to the eyepiece lens assembly of the viewing optics body 210 .

[0332] 32 is a representative diagram of a battery compartment 3005 integrated into the base 220. In one embodiment, the battery compartment 3005 is designed so that the battery is inserted positive first into the bottom of the battery cavity with a mechanical stop to prevent improper installation and operation of the battery.

[0333] In one embodiment, the integrated battery cavity 3005 can use the same gasket as is used in the base 220 for the riflescope body 210. This provides a more reliable seal and eliminates mechanical devices since a separate battery cavity is not required. Secondly, since the battery cavity is integrated into the base, there is no mechanical device to secure the battery cavity. This reduces the need for a mechanical interface to secure the battery compartment. Since there is no need to mechanically lock the battery cavity, the integrated battery compartment reduces the points of failure associated with conventional battery compartments.

[0334] The integrated battery compartment eliminates any obstructions that may get in the way of the user. It is located below the viewing optics where it does not interfere with any of the adjustments and knobs found on conventional viewing optics. It is a significant advancement as it allows for the space needed to accommodate larger batteries.

[0335] In one embodiment, the viewing optics can be configured in a manner that minimizes battery drain and maximizes battery life. For example, a viewing optic equipped with a laser range finder is activated when an operator presses a button or switch. A display shows the range finder's designator. The output laser of the external range finder matches the designator through an initial calibration step when zeroing in the viewing optics. When the operator activates the external range finder, information is sent wirelessly or through a communication port to the viewing optics, signaling the viewing optics that "information has been received and needs to be displayed."

[0336] If the observation optics are powered on and no data is received from the external device, the observation optics will power off after a user set time has elapsed. After displaying the information received from the external device, a power off timer is started which powers off the observation optics if no further button presses are recorded.

[0337] If more information is received from the external device, the screen will clear any previous information, display the updated information, and start the power off timer. This cycle can continue for any number of times selected by the operator.

[0338] While the information is displayed on the screen, a cant indicator is displayed on the screen. This is refreshed at certain intervals from an accelerometer that communicates with the microcontroller. When the microcontroller is in sleep mode, an integral button on the viewing optics controls the brightness of LEDs that illuminate a glass-etched reticle. When the viewing optics is active, control of these LEDs is suspended and the screen brightness changes with the corresponding button press.

[0339] 3. Picatinny Mount In one embodiment, the present disclosure relates to a viewing optic having a body and a base with a battery compartment, and a Picatinny mount that can be coupled to the battery compartment. In one embodiment, the detachable Picatinny mount is attached to a protruding battery compartment integrated into the base that is coupled to the riflescope body.

[0340] 33-35 are representative schematic diagrams of a riflescope including a body 210 and a base 220 coupled to the body 210, the base having a battery compartment 3005 mountable to a Picatinny mount 3305. In one embodiment, the Picatinny mount 3305 is aligned with the battery compartment 3005 and secured thereto by a fastener.

[0341] Attaching the mount 3305 to the battery compartment 3005 of the base 220 utilizes the material needed to create the cavity 3005 for the battery. This eliminates the need for additional material from the base, thereby making the viewing optics lighter and less intrusive.

[0342] In one embodiment, the mount is positioned away from the turret and parallax knob toward the objective lens so as not to interfere with the user's ability to adjust the riflescope. Additionally, the top ring is removable, allowing for easy attachment of auxiliary devices, such as a laser range finder. By utilizing the Picatinny mount disclosed herein, no additional structural support is required from the upper portion of the ring, as the integrated base secures the riflescope.

[0343] In one embodiment, the mount incorporates a cantilevered Picatinny rail that extends forward toward the riflescope objective. This allows the weapon mounted laser range finder to be seated directly above the bell of the riflescope. This mounting style allows for reduced shot misalignment and increased accuracy of the range finder device. It reduces the chance of shot misalignment since there are fewer variables affecting the range finder device due to the acquisition of the desired target.

[0344] 4. Data Port In one embodiment, the present disclosure relates to an observation optical instrument comprising a body and a base with an active microdisplay for generating an image and combining the generated image with an image of a scene at a first focal plane of the body of the observation optical instrument, the base having an axially oriented data port for interfacing with auxiliary devices including, but not limited to, a remote control switch and a laser range finder.

[0345] 36 is a representative schematic diagram of a riflescope 3600 having a body 210 and a base 220 with an axially oriented data port 3605. In one embodiment, the viewing optics can have one axially oriented data port. In another embodiment, the viewing optics can have two or more axially oriented data ports.

[0346] Utilizing an axially oriented data port 3605 minimizes the top-down profile of the entire viewing optics, thereby improving the robustness of the mounted system and its connections.

[0347] 5. External Video Source In one embodiment, the active display in the base can be used as the optical train or optics of the clip-on device, including but not limited to thermal imaging and night vision systems.

[0348] Thermal imaging systems allow the user to image and communicate to the user various waves of the electromagnetic spectrum that are generally not captured by the human eye. Traditional thermal weapon sights consist of two pairs of systems; infrared optics that view the scene, and visible wavelength optics, which consist of a microdisplay and lenses to recreate this image on the front of the riflescope. There are also cases of catalytic photon enhancement, which creates what are known as "night vision" systems. However, clip-on devices are typically attached to a rifle rail at the front of the riflescope body. This configuration blocks all of the ambient light that is typically imaged by the scope, allowing only the digital image to be used. To switch back to a traditional image, the user must remove the system from the rail. This can cause bullet misalignment due to alignment settings that must be made every time the sight is changed. These clip-on units also tend to be large, as they require an eyepiece / imaging system behind the digital display within the unit. With traditional systems, any live video feed is a fully digital image, including the visible spectrum output.

[0349] FIG. 37 is a representative schematic diagram of a riflescope 3700 having a body 210 and a base 220 with an active display 1210 and a concentrator optic 1220 that can be used as an optical system for a thermal imaging unit 3705. The active display 1210 generates an image that is focused on a first focal plane of the body of the scope and integrates this image with conventional daylight optics using a beam combiner. The integration of a digital display allows the user to overlay a digital image on the surrounding daylight optics. With the digital display disclosed herein, there is no need to remove the clip-on unit from the front of the observation optics to view the surrounding daylight optics. Instead, the digital display can be turned on and off as needed.

[0350] The integration of the digital display ensures zero image shift when switching between daytime visible optics and digital optics. There is no need to zero in the digital optics every time they are turned on, as the system is fully integrated. The system is synchronized by aligning the combiner optics.

[0351] In one embodiment, the integration of the digital display provides an optical train that is typically the rear half of the clip-on unit. Since there is already a microdisplay in the base of the observation optics, only infrared optics are needed for thermal aiming: the image generated by the thermal sensor is transmitted to the active display, which is already integrated into the base of the observation optics. This integration of thermal or night vision aiming makes the thermal / night vision device much shorter and lighter than weapon sights currently on the market. This allows the design of a smaller and lighter system, since half of the optical train is integrated directly into the base that mates with the body of the observation optics. There is no need to integrate rear optics or a display into the clip-on unit that houses the sensing device.

[0352] Furthermore, if a thermal weapon sight were mounted on the side of a riflescope so that the thermal optics did not obscure the riflescope objective lens, it would be possible to superimpose a thermal image over the visible image observed by the user. This would have the advantage of being able to highlight people, animals, or anything with a thermal signature that would otherwise not be noticeable in a neutral daylight scene.

[0353] In one embodiment, the integration of a digital display as disclosed herein creates the advantage of providing a live video feed into the focal plane of the viewing optics without obscuring daylight visible sights.

[0354] In one embodiment, the integration of digital displays allows for seamless integration of imaging overlays, such as live thermal imaging, and hyperspectral overlay systems. The visible image is now analog, rather than a separate digital display.

[0355] In one embodiment, the integration of digital displays as disclosed herein provides the advantage that even if power suddenly runs out on the digital system, the image feed continues: a true analog image will still be available, which is not the case with traditional digital output systems.

[0356] In one embodiment, the integration of a digital display allows multiple types of imaging systems to be mounted off the front of the viewing optics: a thermal imaging system can be aligned with the bottom or side of the viewing optics and still deliver its image directly onto a focal plane within the body of the viewing optics.

[0357] 6. EMI transparent window In one embodiment, the body, base, or both the body and base of the viewing optics can have a window sealed with a material that is transparent to the electromagnetic waves used for wireless communication, including but not limited to plastic, resin, or epoxy.

[0358] In one embodiment, the window allows electromagnetic waves to propagate from the communication device with reduced interactions from metallic objects in the observation optics, which increases the speed at which data can be transmitted, and allows the wireless communication device to operate at lower power levels due to reduced signal loss.

[0359] III. Additional Sensors / Devices In another embodiment, the present disclosure relates to a viewing optical instrument having a body and a base with an integrated display system and one or more sensors, in one embodiment, the sensors include, but are not limited to, a global positioning system, an accelerometer, a magnetometer, a MEMS rate sensor, a tilt sensor, and a laser range finder.

[0360] A. Pointing angle, target location, and communication In one embodiment, the observation optics can have an inertial MEMS rate sensor to determine the pointing angle of the weapon in inertial space. Exemplary products are Systron Donner's LCG-50 and Silicon Sensing's SiRRS01. In another embodiment, an accelerometer can be incorporated into the embedded electronics to determine the absolute tilt angle of the observation optics and track the acceleration of the weapon due to typical movement or firing events.

[0361] To assist with targeting, various embodiments may include the observation optics, a GPS, and / or a digital compass. In one embodiment, the GPS and / or digital compass may be integrated into the observation optics, for example as a board-level module. In another embodiment, the GPS and / or digital compass may be associated with a separate device that communicates with the observation optics.

[0362] Several manufacturers offer custom off-the-shelf modules for GPS and digital compass functions with small form factor 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, consumes less than 30mA, and is smaller than 3 / 4 inch square. One example of a GPS device is the Delorme GPS2058-10 module, available in a surface mount package that measures 16mm x 16mm and provides an accuracy of 2 meters.

[0363] In one embodiment, the observation optics can have data interfaces providing either or both wired and wireless capabilities designed to interface with systems such as BAE Personal Network Nodes and emerging SRW radios. These interfaces provide various communication capabilities such as range, sensor, and other tactical data (e.g., friendly fire detectors, environmental sensors, etc.). This unique capability is used in various embodiments to acquire and communicate environmental, target, and situational awareness information to a community of interest. Generally speaking, various embodiments are designed to enable a soldier to rapidly acquire, reacquire, process, and otherwise integrate data from a variety of passive and active sources into a ballistic delivery solution, thereby enhancing the effectiveness of the shooter.

[0364] In another embodiment, the sensor provides information to the active display to generate real-time position data of different targets on a first focal plane of the body of the observation optics. In another embodiment, the sensor is part of an external device that communicates with the integrated display system.

[0365] By using such sensors within the observation optic, or on an external device tightly connected to the observation optic, or on the weapon on which the observation optic is mounted, the exact position of the observation optic can be obtained as well as the exact direction in which the observation optic is pointed, and the external target can be calculated in relation to the position and aiming direction of the observation optic.

[0366] As the user moves the viewing optics around or as the target moves relative to the viewing optics, the position of the target is continuously updated in real time by sensors in communication with the integrated display system so that the user can ascertain where the target is in relation to its visible position by looking through the viewing optics.

[0367] This technique has strong utility in military applications where personnel may be in different locations and attempt to communicate specific target locations to each other. For example, in close air support (CAS), a pilot may fly the aircraft and ground forces may rely on the aircraft to drop bombs on the target. Often, it is difficult for ground forces to communicate the exact location of the target to the aircraft. The process of communicating targeting information between ground forces and aircraft is often referred to as "keeping the target talking" and involves communicating what the force or aircraft sees in its field of view, such as what landmarks are visible near the target.

[0368] This process often takes a significant amount of time and can be confusing because the target often looks different from the air than it does on the ground. It is vital that forces are confident that they are all looking at the same target, because if an aircraft mistargets it, it could drop bombs on friendly forces or non-combatants.

[0369] These problems are solved by having position and attitude sensors communicate with the active reticle display of the Integrated Display System. A user of the observation optics can designate a target in the scope, and the scope, knowing the GPS location of the scope, the exact direction it is pointing, and the distance to the target, can calculate the target's precise GPS coordinates. This information can be fed into a universal system, such as Link 16, to which all friendly forces are connected. Then the aircraft simply has to look at its own display, and as soon as another force designates a new target, that target appears on the map.

[0370] This makes target detection much faster and makes it much easier to ensure that both forces are looking at the same target. Because precision is so important in determining the target's location, the image produced by the active display must be displayed in a first focal plane of the body of the observation optics. If the image produced by the active display is projected into a second focal plane of the body of the observation optics, the target location will only be accurate when the observation optics reticle is in its "zeroed" position. If the user of the observation optics turns the turret any amount, for example to align with a long-range target, all of the target information in the display will shift by the amount the turret has been turned and will not be accurate.

[0371] By using this with the active display image introduced into the first focal plane, the data displayed is independent of adjustments made to the reticle position and is automatically corrected, meaning that the target data in the field of view is always accurate.

[0372] B. Environmental Sensor In one embodiment, the observation optics may include one or more pressure, humidity, and / or temperature sensors designed to collect and use environmental data for ballistic correction. Sensors are available in compact configurations suitable for incorporation into the observation optics. An example of a compact, low power, waterproof air pressure sensor is the MS5540 manufactured by Intersema. The size of this component is 6.2 x 6.4 mm.

[0373] In one embodiment, the sensor may be coupled to the main tube of the viewing optics or to the base of the viewing optics.

[0374] C. Uphill and downhill In one embodiment, the viewing optics can have a z-axis accelerometer that can be used to measure the tilt angle of the scope relative to the vertical. This tilt angle can be incorporated into the ballistic solution at the time of target selection. Once a target is selected, the system can automatically incorporate the actual upslope or downslope tilt into the ballistic solution and display the solution in the first focal plane of the viewing optics so that the digital reticle or modified aim point is displayed correctly. This can provide a very rapid and effective means of aiming in long range upslope or downslope engagements.

[0375] IV. Observation optics with display system and laser range finder In one embodiment, the present disclosure relates to a viewing optic having a body and a base with an integrated display system, and a laser range finder. In one embodiment, the laser range finder is coupled to the viewing optic. In another embodiment, the laser range finder is separate from the viewing optic and communicates with the viewing optic wirelessly or via a cable.

[0376] In one embodiment, the laser range finder is coupled to the observation optics by a mounting rail that is attached to the base through the battery compartment.

[0377] In one embodiment, a laser range finder can be used to determine the distance to a target. In various embodiments, the laser transmits in the near infrared for stealth. A typical wavelength used for laser range finder devices operating in the near infrared (NIR) is 905 nm.

[0378] In one embodiment, the particular laser power and spectral characteristics are selected to meet the distance and eye safety requirements of the viewing optics. The range finder is of sufficient power to produce accurate measurements, illustratively up to 1500 meters, 2500 meters, or other effective distances associated with firearms or weapons intended for use with the viewing optics. With respect to the operation of the range finder, in some embodiments, a single button control is dedicated to making or performing range finder measurements.

[0379] In one embodiment, the distance to the target can be communicated to an active display that generates an image of the distance to the target and superimposes the distance to the target on a first focal plane of the observation optics when the target scene is observed.

[0380] In one embodiment, the observation optics has a computing device with ballistic calculation capabilities.In one embodiment, the body of the observation optics has a computing device with ballistic calculation capabilities.

[0381] In one embodiment, a laser range finder can be used to measure target distance, calculate the projectile trajectory, and communicate a corrected aim point to an active display in an integrated display system, which then superimposes an image of the corrected aim point onto a first focal plane of an observation optics having a reticle mounted on a movable erecting lens system.

[0382] Importantly, because the image generated by the active display is combined with an image from the target in front of the first focal plane and then focused to the first focal plane, the target image and the display image never move relative to each other, so any aiming reference generated by the digital display will always be accurate, regardless of how the moving erector is adjusted.

[0383] When an external laser rangefinder provides distance information to the riflescope, a sighting reference or laser designator must be created on the digital display so the user knows where in the field of view the LRF is aimed to hit the correct target with the laser. The digital display image and the objective lens system target image on the riflescope body do not move relative to each other. Thus, the digital laser designator can accurately show the user the correct location of the LRF laser aim point no matter how the turret is adjusted to move the movable erector lens system.

[0384] On the other hand, if the digital display image were integrated into the optical system somewhere behind the first focal plane, then when the erector lens system is moved / tilted by adjusting the turret, the digital display image would move relative to the target image and the digital LRF designator would move relative to the actual laser aim point. This can lead to inaccurate distance measurements if the user dials in any elevation or windage adjustments on the turret and forgets to move the turret back to the original position it was set to when the user aligned the digital reticle with the actual laser aim point.

[0385] Furthermore, when zeroing a conventional riflescope on a rifle, the user typically selects a "zero" distance, often 100 yards, which is used to align the riflescope's reticle with the point of impact of the rifle's projectile. This is typically accomplished by adjusting the riflescope's turret, and thus the tilt angle of the erecting lens system, to align the reticle with the point of impact of the rifle's projectile. After the initial "zero" of the riflescope is set, the turret allows the user to make further adjustments to the riflescope's reticle position to compensate for targets at different distances and to compensate for changing windage variables that affect where the projectile's point of impact changes from the initial "zero" position.

[0386] If a digital display is integrated into the riflescope system behind the first focal plane, the correction factors for the ballistically calculated aim point may be inaccurate if the user makes any adjustments to the turret from the initial "zero". For example, if the ballistic calculator determines that a 10 milliradian elevation adjustment is required to hit the target, the digital display will place the aim point 10 milliradians below the center of the crosshair. However, if the user dials in the elevation turret 5 milliradians from the initial "zero" position, the digital aim point will actually aim 15 milliradians below the initial "zero".

[0387] Introducing the digital display in the first focal plane of the riflescope's body optics makes the digital display completely independent of any changes in the turret adjustment or erector position, i.e., in the above example, the digital aim point would only appear 5 milliradians below the center of the reticle for a total correct ballistic drop of 10 milliradians (the user had previously rotated the elevation turret by 5 milliradians from the initial "zero" position). In short, introducing the digital display image in the first focal plane of the body optics makes the digital display image completely independent of any changes in the turret position and thus any movement / tilt of the erector lens system, providing the required precision.

[0388] In one embodiment, the capabilities of the laser range finder provide ballistic solutions that are dynamically determined based on acquired data. The range to the target can be used by an on-board computer when processing the tracer trajectory to determine the best point along the measured trajectory path to use to determine the ballistic correction for the next shot.

[0389] In one embodiment, the laser range finder is integrated into the scope and has a dedicated output laser transmission port. In one embodiment, the optical path of this dedicated laser axis is positioned in a corner of the housing so that it is not blocked by the main objective lens. The detection path for the incoming reflected laser signal is through the main objective lens of the scope, and the light is directed to a photodetector by a near-infrared beam splitter. This arrangement takes advantage of the relatively large aperture of the main objective lens to increase the signal-to-noise ratio of the measurement.

[0390] 38-44 provide photographs of viewing optics 3800 having a body 3810 with optics and a base 3820 having an integrated display system and coupled to the body 3810, with a laser range finder 3830 coupled to the top of the body 3810. The viewing optics 3800 can have two auxiliary ports 3805 for communication with external sources. The viewing optics 3800 can have a Picatinny mount 3305 that couples to the outside of the battery cap to the battery cavity 3005 in the base 3820.

[0391] 45-46 provide an illustration of a viewing optics 4500 having a body 4510 with an optics system, a base 4520 having an integrated display system and coupled to the body 4510, and a laser range finder 4530 coupled to the top of the body 4510. The viewing optics 4500 can have a single auxiliary port 4535 for communication with the laser range finder 4530.

[0392] 47 and 48 provide an illustration of a viewing optics 4700 having a body 4710 with an optics system and a base 4720 having an integrated display system and coupled to the body 4710. In certain embodiments, the viewing optics 4700 can have a Picatinny mount 4730. In certain embodiments, the viewing optics can have an auxiliary port 4735.

[0393] V. Additional Embodiments 1. Digital zero adjustment In one embodiment, the present disclosure relates to a method of using a digital reticle for alignment and zeroing. In one embodiment, a viewing optic has a physical reticle and a digital reticle, the physical reticle is connected to a mounting system. A user "zeroes" the physical reticle using a turret and moves the reticle and mounting system so that the center of the reticle coincides with the impact point of a bullet.

[0394] After the physical reticle is zeroed, the digital reticle also needs to be zeroed. Since the digital reticle is formed by an active or digital display with a fixed position, the only way to zero or align the digital reticle is by using digital means. The position of the digital reticle can be moved by the user so that the center of the digital reticle coincides with the center of the physical reticle.

[0395] In another embodiment, digital zeroing can also be used with a laser designator. When used in conjunction with an external laser range finder, the laser designator on the viewing optics must be aligned with the direction the laser range finder is pointing. Most external laser range finders have a visible laser and an infrared laser. The infrared laser is the laser that actually measures distance. The visible laser can be turned on and off and matches the aim of the infrared laser. The visible laser allows the user to see where the laser is aimed. Once the visible laser is on, the user can digitally adjust the laser designator to match the aim point of the visible laser. The visible laser can then be turned off and the user can use the laser designator in the viewing optics display to ensure accurate aim of the laser range finder.

[0396] 2. Holographic Waveguide In one embodiment, the present disclosure relates to an observation optical instrument having a body with a first optical system and a base with an active display and a holographic waveguide. In one embodiment, the integration of the holographic waveguide reduces the package size and weight of a conventional beam combining system. The integration of the holographic waveguide can increase the overall transmitted brightness ratio so that a larger proportion of the light from each optical system can reach the end user.

[0397] 49 is a representative diagram of observation optics 4900 with optics in body 4910, a base with active display 1210, and a holographic waveguide system 4925. The holographic waveguide system 4925 spans the body 4910 as well as the base 4920. The digital display or active display 1210 generates an image on collimation optics 4930 which sends the image to input hologram waveguide 4926. The image exits the waveguide via output hologram 4927 and is introduced into the first focal plane 4930 of optical system 4940.

[0398] In one embodiment, the integration of a holographic waveguide reduces the need for special coatings on the beam combiner. Additionally, the integration of a holographic waveguide eliminates the need for mirror systems and reduces the need for complex mechanical alignment systems.

[0399] The integration of holographic waveguides allows one to create a replica of the complex optics required to image the display, eliminating the need for complex systems to be in place in every system.

[0400] The integration of holographic waveguides allows for the use of LCOS, LCD and OLED systems to display information within the optical system. Due to the nature of the system, different types of illumination systems can be used in conjunction with the different types of displays used within the system.

[0401] The use of a holographic waveguide allows for the implementation of a non-static illuminated reticle, which can change as the image on the screen changes. The holographic waveguide eliminates the need for traditional illumination methods, allowing for a daylight bright reticle system.

[0402] The integration of holographic waveguides creates the ability to generate non-static holographic fields. Output coupling holograms can direct light defined by the master optics, allowing for the changing of the aiming picture of the holographic field.

[0403] The integration of holographic waveguides can be used with any monochromatic or polychromatic light source. The use of complex multiplexed Bragg grids allows the integration of polychromatic illumination systems.

[0404] 3. Bullet Trajectory Tracking One of the difficulties associated with long-range engagements is the ability to determine the accuracy of the first shot so that corrections can be made in time to improve the accuracy of the next shot. Traditional techniques used to determine the point of impact of the round are to attempt to detect the bullet trail and / or the actual bullet scattering point, which can be difficult in many long-range engagements. In the case of a sniper team, follow-up fire also requires feedback from the observer to transmit appropriate data back to the shooter, which can take several seconds using only verbal communication.

[0405] In one embodiment, the observation optics may have an image sensor adapted to detect image frames relating to the bullet's flight path and transmit these image frames to a computing device, where the computing device may calculate the bullet's trajectory from these image frames.

[0406] In one embodiment, a viewing optic having a body and a base with an integrated display system can detect tracers with built-in image processing to determine the trajectory of the bullet just prior to impacting the target area. In one embodiment, this data can be communicated back to a ballistic computer to quickly and efficiently generate a follow-up fire solution for a second round, which can be communicated to an active display with a revised aim point superimposed on the first focal plane of the viewing optic's body.

[0407] Automating the feedback loop with computerized trajectory and splash point detection, coupled with an active display, and superimposed electronic aimpoint correction on the primary focal plane advantageously reduces the total time required to deliver an accurate second shot. This reduction in time can be a critical point in the engagement process. After the first shot is fired, the window of opportunity to deliver a second shot can quickly narrow, especially if it is delayed beyond the point at which the sonic boom of the first shot reaches the intended target.

[0408] Environmental conditions and windage drift can significantly affect a round's ballistic trajectory over long distances. For example, an M193 bullet can drift by about 4 feet at 500 yards in a moderate crosswind of 10 miles per hour. Because bullet velocity decreases as range and total time of flight increase, the effects of windage become even more exaggerated at greater distances.

[0409] A variety of tracer options are available. Standard tracers are traditionally used by shooters to ascertain the trajectory of the bullet within its flight path. Tracer rounds can emit light in the visible or IR spectrum, depending on the composition of the tracer material. The latter is useful if the shooter is using night vision equipment. Additionally, some tracers may initially emit a faint light that brightens as the round progresses along the distance. A fuse element can control the timing of the tracer glow after the round is fired, delaying the ignition of the tracer material until the bullet has progressed far enough along the distance. The fuse delay reduces the risk that the tracer will reveal the shooter's firing position.

[0410] In one embodiment, the observation optics with integrated display system can use tracer rounds to detect, determine, and / or display the trajectory of a bullet immediately prior to impacting a target area. In one embodiment, a covert tracer having a long delay fuse and emitting light in the near infrared region of the electromagnetic spectrum (700-1000 nm) can be used. Light emitted in the near infrared region is invisible to the human eye, but can be detected by imaging sensors using conventional glass optics. This type of tracer round can be particularly useful in maintaining the shooter's stealth for sniper operations, while providing automated bullet tracking capabilities critical for accurately determining next shot correction requirements. Thus, various embodiments are adapted to work with one or more tracer rounds to implement the functionality described herein.

[0411] Standard daylight tracers can also be used for bullet tracking, since the imaging sensor of the daylight embodiment is also sensitive to visible light. In both the visible and near infrared cases, tracer bullets can take advantage of having a long delay fuse for increased stealth, since the system only needs to detect the bullet flight at the last moment before impact.

[0412] In one embodiment, a camera associated with the observation optics can record the trajectory of the bullet, and using a set of sensors embedded in the observation optics, the exact geolocation trajectory of the bullet, as well as the bullet's point of impact, can be calculated.

[0413] In another embodiment, the observation optics can also use a stabilized camera to compensate for recoil from the firearm. The observation optics will accurately track the movement of the stabilized camera and compensate for that movement to accurately calculate the geolocation trajectory of the bullet. This embodiment allows the shooter to accurately track his own trajectory and more accurately correct for any mistakes.

[0414] In both embodiments, the geolocational trajectory of the bullet can then be shared with other users who also activate a display on the device they are using, such as another riflescope, spotting scope, or goggles that use microdisplay or holographic technology to display the trajectory in their field of view.

[0415] In one embodiment, bullet trajectory tracking incorporates capturing video frame images of a glowing in-flight tracer bullet. The spatial location of the bullet within a selected image frame is extracted by image processing techniques and then correlated with data from other video frames to establish the bullet's trajectory.

[0416] Image frames are selected for processing based on correlation with a firing event. When a bullet is fired from a weapon, the time of muzzle exit is immediately determined by processing accelerometer data obtained from an on-board weapon axis accelerometer included in various embodiments. A correlation window from the muzzle exit time is then initiated, where various embodiments begin frame-by-frame processing of the video image to identify a small cluster of pixels associated with a tracer bullet at a particular XY location in space. As the bullet passes through a small number of individual pixels in the XY frame, frame images can be taken with an exposure time optimized to capture the bullet. With the camera frame rate and muzzle exit time 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 associated round, or alternatively is received from a tactical network communication with the weapon sight.

[0417] If the absolute distance to the target is known from the laser range finder measurements, the position of the round at the target distance can be calculated by determining the point on the trajectory that corresponds to that target distance. The advantage of this technique is that the measurements are made from in-flight data and are not dependent on the bullet impacting a physical surface. The calculated position will correspond to the elevation and azimuth angles relative to the weapon's position and can be used to determine the ballistic pointing corrections required to improve accuracy. As part of this next shot ballistic correction calculation, various embodiments use the 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 flight. This allows the calculation to account for any angular motion of the gun that occurred during the bullet's flight time to the target distance.

[0418] 4. Additional configuration 50 shows an alternative embodiment of a riflescope 5000 having 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 with an active display 5015 and collector optics 5020. The integrated display system is oriented such that the display 5015 and collector optics 5020 are parallel to the beam combiner 5025. In this embodiment, no reflective surfaces such as mirrors are required.

[0419] FIG 51 shows an alternative embodiment of a riflescope 5000 having 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 with an active display 5105, collector optics 5110, and a mirror 5115. The integrated display system is oriented such that the display 5115 and collector optics 5110 are perpendicular to the beam combiner 5025. In FIG 51, the active display 5105 is closer to the eyepiece system compared to the objective system of the viewing optics.

[0420] Figure 52 shows an alternative embodiment of a riflescope 5000 having 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 with an active display 5105, collector optics 5110, and a mirror 5115. The integrated display system is oriented such that the display 5115 and collector optics 5110 are perpendicular to the beam combiner 5025. In Figure 52, the active display 5105 is closer to the objective lens system than to the eyepiece lens system of the viewing optics.

[0421] The generated image from the active display 5105 is mirrored and combined with an image of the scene viewed by the observer through the viewing optics using a beam combiner 5025 in the scope body 5005, allowing the generated image and the observed image to be simultaneously superimposed or overlapped, and the combined image is introduced into a first focal plane. Because the beam combiner 5025 is positioned in front of the first focal plane 1510 and the combined image is focused onto the first focal plane, the generated image and the observed image do not move relative to each other. This is a significant improvement over devices that introduce an image into a second focal plane.

[0422] In yet another alternative embodiment, the viewing optics has a scope body and a separable base with an active display and collector optics, the active display and collector optics being parallel to the beam combiner. In this embodiment, no reflective surfaces such as mirrors are required. The base mates with the bottom of the viewing optics body.

[0423] The generated image from the microdisplay 5105 can be combined with an image of the scene viewed by the observer through the viewing optics using a beam combiner in the scope body to simultaneously superimpose or overlap the generated image and the observed image, and the combined image is introduced into a first focal plane. Because the beam combiner is positioned in front of the first focal plane and the combined image is focused onto the first focal plane, the generated image and the observed image do not move relative to each other. This is a significant improvement over devices that introduce an image into a second focal plane.

[0424] The optical sights and methods disclosed herein may be a display or viewing apparatus, device, sight, or scope for, on, or as part of, or as an add-on accessory to, a weapon, gun, rifle, laser target locator, range finder, etc. Embodiments may be mounted on a weapon or apparatus, or may be hand-held or helmet-mounted.

[0425] V. Observation optics with advanced reticle features A. Active display patterns based on magnification settings In one embodiment, the present disclosure relates to an observation optical instrument having a body and a base with an integrated display system, an active display of the integrated display system generating a plurality of reticle patterns projected onto a first focal plane of a field of view.

[0426] In one embodiment, the present disclosure relates to a viewing optical instrument having a body and a base with an integrated display system, an active display of which generates a reticle pattern based on a magnification level.

[0427] In one embodiment, the present disclosure relates to a viewing optic having a body with one or more sensors capable of tracking or monitoring the magnification level of the viewing optic and a base with an integrated display system, where an 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.

[0428] In one embodiment, viewing optics with an integrated display system can project a digital signature or aim point that is optimized for the particular magnification setting being used.

[0429] In one embodiment, the body of the observation optics has a sensor associated with the magnification adjustment mechanism of the aiming device to generate a signal indicative of an adjustment of the optical magnification of the observation optics. The observation optics further includes an electronic controller in communication with the sensor and the active display of the integrated display system. In response to the signal generated by the sensor, the electronic controller is in communication with the active display to generate a reticle pattern that is superimposed on an image of a distant object and viewable through the eyepiece within the field of view.

[0430] In some embodiments, the electronic controller and active display can be configured to generate a first reticle pattern, such as a close combat reticle pattern, in response to a signal indicative of a first magnification setting, and to generate a second reticle pattern, different from the first reticle pattern, in response to a signal indicative of a second magnification setting greater than the first magnification setting. For example, the second reticle pattern can be a long-range reticle pattern, such as a sniper reticle.

[0431] In some embodiments, the sensor may include an electromechanical or optical digital encoder (which may be rotary or linear), a potentiometer, a combination of one or more magnets and one or more Hall effect sensors, or other suitable device operable to sense the position or movement of the magnification adjustment mechanism and generate a corresponding electrical signal. In one embodiment, the sensor is depicted in FIGS. 69 and 70.

[0432] In one embodiment, the active display is not within the body of the viewing optics.

[0433] In one embodiment, the one or more reticle patterns can be selected from a number of patterns 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 21 or more patterns. In one embodiment, a viewing optic with an integrated viewing system can select from among at least 10, or at least 20, or at least 30, or at least 40, or at least 50 reticle patterns.

[0434] In one embodiment, the active display of the integrated display system projects a reticle pattern based on a particular magnification setting onto a first focal plane of the field of view. When the magnification setting is changed, the reticle pattern generated from the active display switches so that the aim point is immediately useful to the operator. The reticle switching can be based on the magnification setting.

[0435] By way of example and not limitation, at a magnification setting of 1X, the active display may produce a small center dot projected onto the first focal plane. When the magnification is changed to 8X, the active display produces a cross-hair pattern with long distance holdover dots projected onto the first focal plane. A sensor determines the change in magnification, which is communicated to a controller, which causes the active display's reticle pattern to be altered.

[0436] In one embodiment, the viewing optics with integrated display system projects information and aim points designed to assist the operator in engaging short and long range targets. In one embodiment, multiple "pages" of information or reticle patterns can be designed and loaded into the system, with different pages being displayed depending on the magnification setting.

[0437] In one embodiment, the reticle pattern from the active display is projected onto an etched reticle in the first focal plane. Projecting the digital reticle onto an etched or fixed reticle provides the necessary protection in case of a system failure.

[0438] Figure 53 is a representative diagram of a close combat reticle 5300 at 1X magnification. The arcuate heavy line 5305, main horizontal line 5307, main vertical line 5309, numbers and arrows are components of the etched reticle. The center dot 5310 is generated from the active display of the integrated display system. This type of reticle is used for close combat and the center dot represents an aiming point for rapid target acquisition.

[0439] Figure 54 is a schematic diagram of the reticle of Figure 53, but with the viewing optics set at 8x magnification. As can be seen, the center dot 5310 projected from the active display is noticeably too large under 8x magnification.

[0440] 55 is a representative diagram of a reticle pattern 5500 that provides useful information when the viewing optics are set to an 8X magnification setting. The arcuate bold line 5502, main horizontal line 5504, main vertical line 5506, numbers and arrows represent an etched reticle. The central aim point 5510, six ballistic compensation windage dots 5520, and the upper left square 5530 showing a rangefinder designator displaying the virtual distance to the target are components generated by the active display.

[0441] FIG. 56 is a representative view of a reticle pattern 5500 at a low magnification setting.

[0442] 53-56, at an optical magnification setting of 1X, reticle pattern 5300 includes a first set of a plurality of marks 5310 (such as circles and / or aiming dots) generated from an active display and projected onto a first focal plane reticle along with etched reticle features 5305, 5307, and 5309. Preferably, reticle pattern 5300 formed at least in part by first set of marks 5310 is a type of close quarters combat reticle (CQB reticle) having minimal marks to provide a less cluttered viewing area, as shown in FIG.

[0443] As the optical magnification setting is increased, the electronic controller and active display (in response to signals received from a sensor, including but not limited to the sensors described in Figures 69 and 70) replaces / alters / swaps the first reticle pattern with a second set of marks, which forms (at least in part) a second reticle pattern 5500 that is different from the first reticle pattern 5300 and typically includes at least some different features.

[0444] For example, the second reticle pattern may include different aiming features and additional markings, such as those associated with distance estimation, windage and elevation adjustment calculations, or other suitable markings commonly used in range finding reticles such as that shown in FIG.

[0445] It can therefore be found to be extremely useful to generate multiple "pages" of features and reticle patterns for an active display, store these in a memory system, and automatically switch reticle patterns when an operator changes the magnification settings of the viewing optics.

[0446] B. Active BDC Reticle Ballistic Drop Compensation (BDC) reticles are designed to place hash marks in a portion of the vertical crosshair that is positioned below the horizontal crosshair, and these hash marks are designed to closely match a particular ballistic profile or set of profiles at a particular distance to be attempted.

[0447] However, current BDC reticle designs are fixed designs. This is because the reticles are manufactured using wire, metal, or etched out of glass. Once a reticle is manufactured and installed in a riflescope, it cannot be changed without removing it and installing a new one, which can only be accomplished by sending the scope back to the manufacturer.

[0448] In one embodiment, the present disclosure relates to a viewing optical instrument having a body with an optical system and a base having an integrated display system with an active display, which can generate a BDC reticle that can be manually changed at any time by a user or, further, can be automatically changed in real time by the viewing optical instrument's software and sensors.

[0449] To generate a BDC reticle for the viewing optics disclosed herein, the riflescope can be programmed for the specific ballistic profile of the rifle and the cartridge fired. The viewing optics can then have sensors such as temperature, pressure, humidity, cant angle, tilt angle, etc., as described above, which can help provide real-time updates to the BDC reticle so that it is as accurate as possible for all conditions. This allows the BDC reticle to be customized for each rifle and the specific shooting conditions.

[0450] With the BDC reticle generated in real time by the active display, the shooter has an accurate system for firing accurately and quickly at a variety of distances.

[0451] As shown in Fig. 57, the reticle 5700 has a standard etch and fill portion including numeric markings and hash marks along the main horizontal lines 5702, the main vertical lines 5704, and the main vertical crosshairs. The reticle 5700 also has patterns and marks generated by an active display and projected onto the first focal plane reticle. The active display marks in this form of BDC reticle include numeric markings 5710 (100 to 900 on the vertical axis in the third and fourth quadrants). This portion is projected from a digital display so that it can be updated in real time.

[0452] In addition to an active BDC reticle, the user / shooter may find himself in a position to support other personnel in areas where targets may appear rapidly and at various distances. For example, a shooter on top of a building looking down an alley or road with a cross street or entrance / exit. The active display can be used in conjunction with various sensors built into the riflescope such as compass, cant angle, tilt angle, GPS, etc. to precisely determine the direction the riflescope is pointing.

[0453] Using observation optics with an environmental sensor, an integrated display system with an active display for generating and projecting a BDC reticle onto a first focal plane, and a range finder, a user can aim at known landmarks such as doors, windows, cars, etc., and place distance markers on those landmarks using the controller and active display. These distance markers are projected onto the first focal plane and are visible through the observation optics. The environmental sensor allows the user to move the observation optics to observe a different target, but the distance markers remain on the target.

[0454] FIG. 58 is a representative image of a BDC reticle generated by an active display and projected onto a first focal plane reticle, displaying distances to potential targets. A viewing optic having a body with an environmental sensor and a base with an integrated display system with an active display for generating a BDC reticle allows a user to mark multiple targets in one or more regions with distances. In this way, if a target appears near the target marker, the user can quickly determine the distance to the target without having to aim at the target. The user can then quickly position and align the target with the active BDC reticle.

[0455] C. Reticle that compensates for the cant of the firearm With traditional riflescopes, when shooting long distances, it is important that the firearm and scope are level when firing. As a bullet travels long distances, it is affected by gravity to a degree that the shooter must take into account. Gravity pulls the bullet in a consistent direction toward the ground, causing "bullet drop." The shooter compensates for this bullet drop by aiming higher than the target so that the bullet has dropped to the correct height to hit the target by the time it reaches it.

[0456] Figure 59 is a typical illustration of a cant angle. It can be seen that the triangle is a right-angled triangle with an angle of 10° at the top and a right angle at the bottom. The 10 milliradian side is the side of the triangle that is the hypotenuse, and represents the inclined vertical section of the crosshair. However, gravity acts on the vertical side of the triangle.

[0457] Using trigonometry, we can solve for the length of the perpendicular side with the following formula: Cos10° = x / 10 milliradians. Solving for x results in 9.85 milliradians. So in this example, the user / shooter may have held or dialed in 10 milliradians, but only offset the shot by 9.85 milliradians. At long range, this is enough to miss the target.

[0458] In one embodiment, the present disclosure relates to a viewing optic with an integrated display system that uses an active display to generate a reticle that can compensate for the cant of a firearm, allowing a user to seamlessly perform long-range shooting without worrying about cant angles.

[0459] In a conventional riflescope, the reticle is a physical crosshair that is either metal, wire, or a pattern permanently etched on glass. This means that the cant of the reticle is always fixed. However, with active display technology that produces a real-time reticle, the digital reticle can be changed at any time by overlaying it on top of the passive image. In one embodiment, the viewing optics has an internal cant sensor that can instantly orient the reticle produced by the active display to correct the cant angle.

[0460] FIG. 60 is a representative diagram of a reticle 6000 generated by an active display of an integrated display system with marks and patterns oriented for cant. The main horizontal line 6002 and main vertical line 6004 are provided by a passive or etched or fixed reticle. The aim point generated by the active reticle 6020 is corrected for cant and projected or superimposed on the passive reticle. The pivot point 6010 is at the center of the reticle. In this case, the electronic controller / microcontroller will use the information collected from the cant angle sensor and the tilt angle sensor, apply software logic, and communicate with the active display to adjust the aim point 6020 of the generated image to reflect the new zero position, related geometry, and hold point corresponding to the orientation of the firearm at this time. The user will shoot with a digital reticle generated by the active display instead of a passive or fixed reticle.

[0461] In another embodiment, the active display of the integrated display system can generate a digital reticle that compensates for cant and compensates for up-tilt or down-tilt shooting by adjusting the aim point on the digital reticle up or down, eliminating the need for cosine indicators that are often used to compensate for shooting in these types of situations.

[0462] D. Digital reticle with drift indicator In conventional riflescopes, reticles with wind indicators are usually glass-etched reticles. Often these reticles have a grid pattern or a row of dots to allow the user to have a reference point to use for aiming and compensating for wind speed. The problem with these reticles is that they are physically and permanently etched onto a piece of glass, so their shape and size are fixed.

[0463] In one embodiment, the present disclosure relates to a viewing optic having a body and a base with an integrated display system having an active display for generating a digital reticle that uses a drift indicator to compensate for 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 viewing optic can have a reticle that can adapt real-time windhold to the trajectory, distance, and environment of a particular situation.

[0464] Generally, the longer the distance, the greater the effect cross winds have on a bullet. With a digital reticle, the wind hold can be made wider as distance increases to compensate for the wind value at a particular distance to the target.

[0465] Figure 61 is a representative diagram of a reticle 6100. Multiple components or markers are provided by a passive reticle including a primary horizontal crosshair 6102 and a primary vertical crosshair 6104. The active display of the integrated display system generates and projects a target 6105 ranged to 500 yards and a wind hold 6110 for the specified conditions. The end of the secondary horizontal line (crossing the primary vertical line) equates to a 5 mph drift, the next dot is 10 mph, and the outermost dot is 15 mph. The images 6105 and 6110 generated from the active display are superimposed on the passive reticle.

[0466] FIG. 62 is a representative diagram of a reticle 6200. Multiple components or markers are provided by a passive reticle including a primary horizontal crosshair 6202 and a primary vertical crosshair 6204. The active display of the integrated display system generates and projects a target 6210 ranged to 1000 yards and a wind hold 6220 for the specified conditions. The end of the horizon (across the primary vertical) is equivalent to a 5 mph drift, the next dot is 10 mph, and the outermost dot is 15 mph. The images 6210 and 6220 generated from the active display are superimposed on the passive reticle. It can be seen that the secondary horizontal line 6220 extends wider and the wind dots are spread further on either side compared to the 500 yard (FIG. 61) solution to compensate for the additional drift induced as the bullet travels longer distances.

[0467] E. Reticle with central grid for second fire correction Traditionally, passive reticles have been designed to allow the shooter to have many reference points for shooting in various conditions and with various trajectories. However, because the variety of conditions and trajectories varies so widely, these reticles tend to have many features on the reticle, such as lines or grids of dots, that cause the reticle to appear cluttered or busy to the user.

[0468] In one embodiment, the present disclosure relates to a reticle system that includes a digital reticle that is generated on an active display and overlaid on a passive reticle. The use of a digital reticle allows information to be displayed appropriately as needed, eliminating the need to display certain information on the passive reticle, thereby providing a cleaner or more easily distinguishable passive reticle.

[0469] In one embodiment, the present disclosure relates to viewing optics having a passive or analog reticle designed to work most efficiently in conjunction with an active reticle. Active reticle technology allows the viewing optics to perform complex calculations and display a ballistic solution to the user. Typically, the ballistic solution is not in the center of the field of view or in the center of the passive reticle's crosshairs. This gives the user the option to either hold over the center of the ballistic solution or rotate the turret and fire until the ballistic solution is in the center of the field of view and in the center of the passive crosshairs.

[0470] In one embodiment, the present disclosure relates to viewing optics with analog and digital reticles that allow the shooter to make the most effective and efficient second fire corrections while minimizing the obstruction of the field of view caused by previous passive reticles that use vast grids of lines and dots.

[0471] Figure 63 is a representative diagram of a wide-angle view of a reticle 6300 at low magnification. A less obtrusive row of dots is used below the horizontal crosshairs. This passive reticle can be used as a backup in the event that the viewing optics' battery power or electronics fail to produce an active display.

[0472] Fig. 64 is a representative diagram of a close-up view of a central portion of a reticle 6400. Fig. 64 provides a higher magnification view. This image shows a small grid 6410 generated by the active display of the integrated display system and positioned in the center of the reticle, allowing the user to make precise measurements of first shot impact locations to make precise second shot corrections.

[0473] In one embodiment, the grid 6410 generated by the active display is wider than it is tall. This is specifically designed because the elevation calculation of impact for the first shot is more accurate than the drift estimation. In this embodiment, the small positive features of the small grid are very fine features that are not illuminated, allowing for very precise measurements.

[0474] In an active or digital reticle, the first shot must be acquired very close together, so the central grid can be much smaller than a typical passive reticle, which requires a large grid that covers a significant portion of the field of view below the horizontal crosshair.

[0475] VI. Automatic Brightness Adjustment As discussed throughout this application, an integrated display system allows a digital image generated by an active display to be superimposed on an image of an external scene. The active display introduces the image of the external scene using an illuminated portion of the display. To maximize usability of the display, it is desirable to have a high contrast ratio between the luminance of the passive scene and the luminance of the illuminated display so that both are easily visible. If the display is too dark, the user cannot see. If the display is too bright, it overwhelms the passive scene.

[0476] In one embodiment, the present disclosure relates to a viewing optical instrument having a body with an integrated display system and a light sensor capable of detecting and compensating for the brightness of a particular target.

[0477] Fig. 71 shows a representative schematic diagram of a viewing optics 7000 with a body 7005 and a base 7010 coupled to the body. The body 7005 has optics for viewing an image of an external scene and a beam combiner 7020 above which a photosensor 7025 and an optical filter 7030 are positioned. This allows the photosensor to view the target scene directly without obstructions in its field of view. The base 7010 has an integrated display system 7015 with an active display for generating an image projected onto a first focal plane of the viewing optics.

[0478] The photosensor 7025 and light filter 7030 create a high contrast ratio between the brightness of the image of the external scene and the brightness of the image generated from the active display.

[0479] In one embodiment, the transmission band of the filter in front of the photosensor can be tuned narrow enough so that only the brightness of the target is measured, and not additional light from the display system that would distort the measurement.

[0480] VII. Optical observation equipment with automatic distance measurement capabilities In one embodiment, the present disclosure relates to a viewing optics with an integrated viewing 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 a viewing optics with an integrated viewing system, a camera to assist in automatic ranging, and a laser range finder.

[0481] In one embodiment, the present disclosure relates to a viewing optics having an integrated display system and a camera incorporating image recognition technology. The systems and methods disclosed herein significantly increase the speed at which a target solution is obtained and eliminate the need for button presses that may affect the aim point. Additionally, the systems and methods disclosed herein integrate artificial intelligence into the system to determine the quality of the ranged target solution.

[0482] In one embodiment, the viewing optics includes a camera incorporating image recognition technology, in one embodiment, the camera can be mounted on either the viewing optics or the firearm with an integrated viewing system and point in the direction of the riflescope's aim point.

[0483] In one embodiment, the camera has artificial intelligence for detecting targets and communicating with the active display of the integrated display system to highlight the targets. In another embodiment, the artificial intelligence system can be integrated into the viewing optics. In one embodiment, the artificial intelligence system can be located in a base coupled to the body of the viewing optics.

[0484] In another embodiment, a thermal imaging camera lacking image recognition technology can be used. This allows the thermal image to be transmitted to an active display and superimposed on the image of the external scene in the viewing optics. The viewing optics can be programmed to display only "hot spots" of interest. For example, hot spots may indicate human heat, or vehicle heat, etc. By eliminating artificial intelligence, the power consumed by the system is greatly reduced. Furthermore, all suitable hot spots appear in the field of view, and the user can evaluate each hot spot to determine whether it is a valid target.

[0485] After identifying a valid target, the user simply moves the viewing optics so that the LRF designator in the field of view is over the desired hotspot. As soon as the LRF designator is aligned with the hotspot, the system automatically activates the LRF to acquire the hotspot distance. After acquiring the distance, the viewing optics can display a hold point for the target distance or simply indicate the distance, and the user can use the active BDC mode to hold on the active BDC reticle for the appropriate measured distance to the target.

[0486] An added feature to the system is that it can automatically detect if the hotspot remains in the LRF designator long enough to obtain a valid range. If not, it will wait to display the range until the hotspot remains in the LRF designator long enough to achieve a valid target acquisition before displaying the solution. This eliminates the second problem with button presses.

[0487] In one embodiment, the present disclosure relates to techniques and methods involving the use of an overlaid camera image projected onto a first focal plane of viewing optics and using this image in conjunction with an LRF designator to automatically range targets.

[0488] VIII. Observation optics equipped with photosensors to save power In one embodiment, the present disclosure relates to a viewing optics with an integrated display system and a power saving system. In one embodiment, the power saving system can be located in a base coupled to a body of the viewing optics. In one embodiment, the power saving system comprises a proximity sensor. In one embodiment, the proximity sensor is in communication with a microcontroller.

[0489] In one embodiment, the power saving system can be used to put the viewing optics into a sleep or standby mode when a user / operator is not looking through the viewing optics, hi one embodiment, the system and mechanism can wake or activate the viewing optics when a user / operator is detected behind the eyepiece of the viewing optics.

[0490] The current method of putting the electronics to sleep or standby is by using a "time out" feature, but this is disadvantageous if the observation optic is being used in close combat missions because the observation optic must remain on for an indeterminate amount of time as long as there is an operator looking through it. An accelerometer can also be used to detect movement and turn the system on. The drawback to this method is that if the operator is observing, the gun can go to sleep for long periods of time with little movement, even though the operator is still looking through the observation optic.

[0491] In one embodiment, the present disclosure relates to a system for conserving battery power by turning on viewing optics when there is a detected operator presence behind the eyepiece of the viewing optics.

[0492] In one embodiment, the power saving system can be used with any electro-optical instrument compatible with mounting a proximity sensor within a few inches of the operator's face when using the viewing optics.

[0493] In one embodiment, the present disclosure relates to a viewing optic having a body and a base coupled to the body, the base having a window on a back surface of the base facing toward an eyepiece.

[0494] In one embodiment, the base has a proximity sensor mounted on the carrier, which is mounted in a window located at the end of the base facing the eyepiece. The proximity sensor can transmit a signal to a microcontroller in the base or body when it detects a reflection within a few inches of the window. The distance at which an object activates the sensor can be adjusted at the factory, or software options can be built into the user interface to allow an operator to adjust the sensitivity of the sensor or disable / enable the auto sleep / standby feature.

[0495] 72 is a representative diagram of a viewing optics 7200 having a base 7205. A window 7210 is mounted on the base 7205, facing the eyepiece of the main body of the viewing optics. A proximity sensor and carrier 7215 is mounted within the window 7210 and positioned below the eyepiece.

[0496] 73 and 74 are representative diagrams of a viewing optics 7200 with a base with a power saving system, where the viewing optics 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 viewing optics. A sensor 7215 in the base 7205 of the viewing optics 7200 detects a reflection from the operator's face, thereby waking the viewing optics from a sleep mode. When the operator moves their head from the viewing position, the sensor will no longer see a reflection, causing the viewing optics to go into a sleep or standby mode.

[0497] IX. Observation optics with power rails In one embodiment, the present disclosure relates to a viewing optic having a body and a base with an integrated display system, the viewing optic being capable of being powered from an external power source housed in a host firearm. In one embodiment, the viewing optic has a body and a base coupled to the body, with electrical pins integrated into the base for providing power from the firearm to the viewing optic. In another embodiment, the viewing optic can be powered from the firearm using electrical pins integrated into a remote keypad assembly.

[0498] In one embodiment, the present disclosure relates to a method and system for providing additional power to viewing optics for extended periods of time.

[0499] In one embodiment, the present disclosure relates to a viewing optic with a body and a base coupled to the body, the base having a PCB used to control the display, sensors, and user interface of the viewing optic. In one embodiment, the base has a power input pin protruding through the base and contacting a power pad. In one embodiment, the power pad is integrated into a Picatinny rail.

[0500] In one embodiment, the PCB is positioned to allow interaction with the input pin, which in one embodiment is sealed to the base of the riflescope to keep the interior of the riflescope protected from the environment.

[0501] 75 and 76 are representative views of a viewing optic 7500 having a body and a base 7510 with a power pin 7520 protruding through the base 7510. FIG.

[0502] FIG. 77 is an exemplary side profile of the viewing optics 7500 showing the power pins 7520 protruding through the base 7510 of the viewing optics 7500.

[0503] FIG. 78 is a representative view of a side profile of the viewing optics 7500 with the base of the viewing optics made transparent to reveal the power pins 7520 attached to the internal PCB 7530.

[0504] In another embodiment, power provided by the Picatinny rail on the firearm can be delivered to the sighting optic via a remote keypad used to control the sighting optic. In this scenario, the power pin is connected to a PCB in the remote keypad and protrudes through an integrated recoil lug in the remote keypad housing. In this case, power is sent to the base of the riflescope through two dedicated wires in the cable.

[0505] FIG. 79 is a representative image of the top surface of a remote keypad 7900.

[0506] FIG. 80 is an exemplary side profile of the remote keypad 7900 showing the power pin 8010 protruding through the internal recoil lug.

[0508] FIG. 82 is a representative bottom view of the remote keypad 7900 with the cover made transparent to show the PCB 8205 inside the remote body.

[0509] X. Observation optics having a single keypad with multiple functions - Patents.com In one embodiment, the present disclosure relates to a system including a viewing optics having an integrated display system and a remote keypad system with more than one function per keypad button. In one embodiment, the remote keypad can control more than one aspect of the functionality of the viewing optics, i.e., more than one function per button. In one embodiment, the function of the button depends on the state of either a control signal or a software bit.

[0510] In one embodiment, the present disclosure relates to a remote keypad that expands the control a user / operator has over viewing optics and / or auxiliary devices used with the viewing optics.

[0511] In one embodiment, the present disclosure relates to a keypad for a viewing optic and / or one or more auxiliary devices used with the viewing optic. In one embodiment, two or more functions can be assigned to a single button on the keypad, with a software bit or a separate mechanical switch determining the desired function. This can greatly increase the functionality of the viewing optic.

[0512] In one exemplary embodiment, in a first mode, the button can change the brightness of the display, and in a second mode, the same button can activate an infrared pointer on the system. By using the same button for more than one function, the number of buttons required is minimized, keeping the remote keypad small and simple.

[0513] Fig. 83 is a representative diagram of a three button keypad. The remote keypad associated with the viewing optics has three buttons. The top button 8305 is used to increase the brightness of the display, the middle button 8310 is used to activate the laser range finder to range the target, and the bottom button 8315 is used to decrease the brightness of the display. The function of each button depends on the mode of operation.

[0514] In one embodiment, the keypad can have 2, 3, 4, 5, 6, 7, 8, 9, 10, or more than 10 operating modes. In one embodiment, the keypad can be in communication with a processor that sets between 10 and 50 operating modes for the keypad. As an example, a keypad in communication with a processor that has 10 operating modes for the keypad provides 10 functions for each button, which functions will be determined by the operating mode.

[0515] The functionality of the buttons can be changed using several methods. In one embodiment, the user / operator presses and holds a button on the remote keypad for a certain amount of time, which causes the microcontroller to change the functionality of one or more of the buttons. In one embodiment, the operator can press and hold one of the three buttons for an extended period of time, such as one second, which signals the microcontroller inside the viewing optics to change a bit that assigns the button a new functionality. In one embodiment, pressing and holding the top button 8305 for a certain amount of time can set Mode A, pressing and holding the middle button 8310 for a certain amount of time can set Mode B, and pressing and holding the bottom button 8315 for a certain amount of time can set Mode C. By varying the time each button is engaged, additional modes of operation can be activated. For example, holding the button 8305 for five seconds can activate Mode A, and engaging the button 8305 with five quick taps can activate Mode F.

[0516] In another embodiment, the functionality of the remote keypad buttons can be changed via separate mechanical switches on the viewing optics. In one embodiment, the mechanical switch can have three different positions that communicate with three different bits or programs in the microcontroller. These bits or programs can be used to assign different functions to the remote keypad buttons.

[0517] A representative example is shown in FIG. 84. The observation optics has a switch 8400 that communicates with a remote keypad 8300. At a first set point 8405, the top button 8305 of the remote keypad 8300 can be assigned the function of increasing the brightness of the display, the middle button 8310 can activate the laser range finder, and the bottom button 8315 can decrease the brightness of the display. If the mechanical switch 8400 is set to a second set point 8410, the function of the top button 8305 and the bottom button 8315 can be programmed to turn on / off the auxiliary pointing laser on the observation optics, and the middle button 8310 can still be programmed to activate the laser range finder. If the mechanical switch 8400 is set to a third set point 8415, the function of the three buttons can be changed again. For example, if the observation optics is equipped with a digital magnetic compass and position and landmark data are stored in the memory of the microcontroller, information about the position of objects can be displayed in the field of view of the observation optics (augmented reality data).

[0518] In one embodiment, the keypad communicates with a processor in the viewing optics that allows different operating modes to be assigned to each button or switch on the keypad. For example, in one operating mode, the buttons on the keypad have a specific function for marking targets of interest. An operator can range the target using a laser range finder and "mark" the target of interest within the field of view using orientation data from a digital magnetic compass. Buttons on the keypad can be assigned functions specifically suited to this task.

[0519] The center button on the keypad can be used to activate the laser range finder and range the target. Once the target has been ranged, the top and bottom buttons can be used to select from a list of predefined descriptive words to classify the target, e.g., "landmark," "friendly," "enemy," "unknown," etc. Once the operator has completed this action, the mechanical switches can be changed to quickly reassign functions to the remote keypad buttons that allow the operator to change brightness settings, activate the infrared laser, or obtain a ballistic solution for the target's range.

[0520] XII. Observation optics with relative coordinate mapping system In one embodiment, the present disclosure relates to techniques and methods for using observation optics with an integrated viewing system to precisely tag and track targets using relative coordinate mapping systems and / or drone technology.

[0521] Soldiers need to be able to pinpoint the location of enemy targets, share this location with other soldiers, close air support, etc., and easily see these targets by overlaying them in the field of view of their primary optics. The most obvious way to accomplish this is with a combination of GPS, compass heading, altitude, tilt, and range sensors. However, relying on GPS has drawbacks, such as GPS signals requiring a direct line of sight to the GPS satellites, which is not always possible. Using relative coordinate techniques and / or drones can reduce the need for GPS. Relative coordinate techniques are feasible when used in conjunction with observation optics that have an integrated display system.

[0522] In one embodiment, a user can aim the viewing optics with an integrated display system at a landmark or target and "tag" it. If a user "tags" multiple targets, a relative position map can be created from the tagged targets. These tagged targets can be transmitted to other users' viewing optics, who will see the tagged targets displayed in their field of view. All of this target data will then be stored locally in one or more memory devices within the viewing optics.

[0523] In one embodiment, users can also use drones as a replacement for or supplement to tagged targets. This would work by launching a "cloud" of many small drones or micro-drones housing cameras and appropriate sensors to fly over the battlefield and begin tagging and marking landmarks. The drones would be able to share this information with each other and back to the user, who would have it displayed on the active display of their observation optics.

[0524] By using relative coordinate techniques and / or drone clouds, the shortcomings of GPS can be overcome.

[0525] With multiple users and multiple observation optics, there is an inherent redundancy in the stored targeting data. Using drone clouds can further increase that redundancy. With redundancy, there is a much lower chance of signal or data being lost. GPS is required to send and receive data over extremely long distances to and from orbiting satellites. Using other users in the same battlespace, or a cloud of drones in the same battlespace, the network gets closer to users and targets, improving the accuracy of user and target coordinates. GPS is much easier to block due to the limited number of GPS satellites. A cloud of users and / or drones makes it much harder to block all signals, increasing redundancy. By eliminating the need for a GPS module, the observation optical equipment becomes less bulky.

[0526] XIII. Remote device of optical remote device with light emitting function In one embodiment, the present disclosure relates to a remote device configured to control the operation of a viewing optics and having a light emitting capability. In one embodiment, the present disclosure relates to a remote device configured to control the operation of a viewing optics and having an illumination source with one or more light emitting bulbs.

[0530] In one embodiment, a single floodlight or light source is used with a fixed output and is not adjustable in beam divergence, elevation, or azimuth.

[0531] In one embodiment, the remote device with lighting capability has an adjustable beam angle, the size of which can be selected by the user. The beam can be infinitely adjustable via the bezel, have a fixed adjustment controlled via the remote device, or can be adjusted via another means.

[0532] In one embodiment, the illumination source has adjustable intensity: the intensity / power can be adjusted by a menu setting on the remote device of the viewing optics, via a button or switch setting, a rotary knob, a wheel or sliding power bar allowing for infinite adjustment, or via another mechanism of adjustment.

[0533] In one embodiment, the remote device with light emitting capability can be tunable for emission wavelength. For example, the wavelength can be tunable in the color or visible spectrum. The wavelength can be adjusted through a menu setting on the remote device of the observation optics, through a button or switch setting, through a sliding power bar that allows for infinite adjustment, or through another means.

[0534] In one embodiment, the remote device with light emitting capability has azimuth and elevation adjustments to allow for mutual alignment with the aiming laser. The adjustment mechanism can mimic a riflescope or weapon mounted aiming laser. The adjustment mechanism can also use a pivoting head and be secured with a locking collar that the user tightens. The light source can also be adjusted by other mechanisms that precisely or approximately maintain orientation under weapon recoil, impact, and other disturbances.

[0535] In one embodiment, a remote device with lighting capabilities can have a floodlight paired with an aiming laser. The floodlight and laser can be connected in tandem or can have separate adjustments.

[0536] In one embodiment, a remote device with light emitting capabilities may have multiple floodlight sources integrated into a single remote device, such as IR and white light, wide and narrow beam IR floodlight sources, white light sources, IR and SWIR floodlight sources, or any other combination of illuminators. The illuminators may be connected in tandem or may be independently adjustable.

[0537] In one embodiment, the remote device has a physical interface for attaching the illumination source. The illumination source can then be removed and used on the remote device as needed. The illumination source can have its own buttons / controls or can be controlled by buttons / controls already on the remote device or observation optics. The illumination source can have its own battery or can use power already provided to the remote device.

[0538] In one embodiment, the illumination source can have interchangeable heads for emitting light of different wavelengths, which can allow for upgrades, repair / replacement, or changing of the emission wavelength.

[0539] In one embodiment, the remote device with lighting capability has an additional on-board battery. In another embodiment, the illumination source draws power only from the observation optics. In another embodiment, the remote device and / or illumination source draw power from a motorized rail or other mechanism.

[0540] In one embodiment, the remote with floodlight emission capability can be mounted to a Picatinny rail on the handguard. In another embodiment, the remote can be mounted to an M-LOK or Key-Mod slot. In another embodiment, the remote is secured to the weapon via another mounting mechanism.

[0541] In one embodiment, the remote device with floodlight emission capability can be mounted in any orientation on the weapon (12 o'clock, 9 o'clock, 6 o'clock, 3 o'clock, etc.).

[0542] In one embodiment, the remote unit with floodlight emission capability can be wireless and is not connected to the observation optics via a cable. The remote unit can be connected via Bluetooth, ISW, or another wireless interface. In another embodiment, the remote unit is connected to the observation optics via data from a SmartRail or similar system.

[0543] In one embodiment, a remote device with floodlight emission has light created by LEDs. In another embodiment, emission is via lasers. In another embodiment, emission is created via incandescent light bulbs or any other illumination source / method. In systems with multiple wavelengths, beam patterns, and power, illumination sources can be mixed and matched as desired. For example, an illumination source can use LEDs for light spill and lasers to increase light projection. Various light sources with different wavelengths can be independently turned on with the same control or powered simultaneously.

[0544] The remote device cable can be of any length, and in one embodiment, the remote device does not have to be located completely at the end of the handguard.

[0545] The apparatus and methods disclosed herein can be further described in the following sections.

[0546] 1. A body having: (i) a first optical system having an objective lens system that focuses a target image from an external scene onto a first focal plane, an erecting lens system that inverts the target image, and a second focal plane; and (ii) a beam combiner between the objective lens system and the first focal plane; a second optical system having an active display and a lens system that focuses light from the active display; and (ii) a mirror that directs an image from the active display to a beam combiner where the image from the active display and a target image from the objective lens system are combined at a first focal plane and viewed simultaneously; An observation optical instrument comprising:

An observation optical instrument comprising: an optical system configured to define a first focal plane; an active display for generating a digital image that is superimposed on the first focal plane; and a controller coupled to the active display, the controller configured to selectively power one or more display elements to generate the digital image.
