Description

Technology Field

[0001] The present invention relates to control and display technology for optical sights, and more specifically, to a sight system that combines an LED array-based electronic zeroing correction function and a head-up display (HUD) information provision function through a micro-display. Background Technology

[0003] With the recent development of sights of various functions and forms for both military and civilian use, there is a growing demand for new aiming methods that address the drawback of conventional sights requiring the eye to be aligned perfectly with the object, while also considering aiming efficiency and convenience. Furthermore, there is currently a trend shifting from mechanical to optical aiming systems.

[0004] Generally, optical sights include laser and dot sight types. The laser type utilizes a direct-illumination laser target designator (laser point); while it is convenient for aiming due to the laser's small and strong light focus, it is difficult to use unless in a dark environment. Furthermore, the illuminated point is difficult to see in bright daylight due to ambient light, and one's position is exposed at night.

[0005] The dot sight method is an aiming technique utilizing LEDs and an optical system. It employs a method of reflecting LED light onto an optical glass containing an LED within a long, dark tube. It has the advantages of easy aiming even during the day and the inability to detect external light, thereby preventing the location from being exposed.

[0006] Conventional dot sights primarily used a method of creating a single reticle through a single light source and reflective optical system, and adjusting the reticle using mechanical window / elevation adjustment screws.

[0007] However, conventional dot sights rely on a mechanical zeroing method, requiring the user to physically adjust the angle of the lens or light source by turning a screw. This resulted in disadvantages such as extreme difficulty in fine-tuning, potential mechanical backlash during repeated adjustments, and a tendency for the zero point to become misaligned in the event of external impact to firearms or the like.

[0008] Furthermore, since conventional dot sights only provide a aiming point, they were significantly lacking in the ability to provide additional information necessary for shooting (distance, wind direction, temperature, trajectory, etc.).

[0009] Therefore, a new sighting system is required that can simultaneously provide various tactical information while maintaining a high-brightness aiming point, and enable precise electronic zeroing adjustment without mechanical actuation.

[0010] The matters described above as background technology are intended only to enhance understanding of the background of the present invention and should not be construed as an acknowledgment that they constitute prior art already known to those skilled in the art. The problem to be solved

[0012] The present invention was devised to solve the problems of the aforementioned prior art, and aims to provide a sighting system capable of providing an electronic aiming point correction function based on an LED array while also displaying various sensing information in the form of a HUD.

[0013] In addition, another objective of the present invention is to provide a sighting system that enables fine and precise adjustment by adopting an electronic correction method when adjusting the position of the aiming point, while also providing various sensing information such as wind, altitude, temperature, and distance to the user in the form of a HUD through a micro-display.

[0014] The technical problems that the present invention aims to solve are not limited to those mentioned above, and other unmentioned technical problems will be clearly understood by those skilled in the art from the description of the present invention. means of solving the problem

[0017] In the present invention, the optical module preferably comprises: a dichroic mirror that transmits the red light of the red LED array and reflects the green light of the green LEDoS module; a collimator lens that projects the composite light of the red light and the green light onto a front reflective lens; and a front reflective lens that is positioned so that a user can observe from the upper side of the sight housing and reflects the composite light of the red light and the green light projected from the collimator lens.

[0018] The present invention preferably further comprises: an MCU that receives input values ​​for horizontal adjustment (Windage) and vertical adjustment (Elevation) of the aiming point and sensing information from a plurality of sensors to control an LED controller; an LED controller that controls the lighting of individual pixels of the red LED array according to the input values ​​for horizontal adjustment (Windage) and vertical adjustment (Elevation) to electronically move the aiming point and controls the output of the green LEDoS module based on the sensing information; and a non-volatile memory that stores a correction value for moving the aiming point.

[0019] In the present invention, the non-volatile memory is an EEPROM or a flash memory, and it is preferable that the MCU automatically retrieves the final correction value of the aiming point stored in the EEPROM or flash memory and inputs it to the LED controller when power is reapplied.

[0020] In the present invention, the red LED array selectively illuminates a specific pixel or multiple pixels to form a targeting point, and it is preferable that the targeting point moves along the X-axis and Y-axis according to changes in the lighting pattern between pixels.

[0021] In the present invention, it is preferable that the red LED array has a pixel structure of a 32×32 array or a 64 X 64 array.

[0022] In the present invention, the pixel pitch of the red LED array is preferably within the range of 15 to 25 µm.

[0023] In the present invention, a plurality of sensors include a distance measuring sensor, a barometric pressure sensor, a temperature sensor, and a gyroscope sensor mounted on the outer surface of the sight housing, wherein the sensing information of the plurality of sensors is preferably converted into distance to a target, wind direction, wind speed, temperature, or gun attitude information by a green LEDoS module and output in the form of a HUD.

[0024] In the present invention, the front reflection lens is preferably one of a lens selected from a concave lens, an aspherical lens, and a freeform lens.

[0025] In the present invention, it is preferable that the dichroic mirror be inserted into the sight housing while maintaining an angle of 40 to 50 degrees with the upper or lower part of the sight housing.

[0026] In the present invention, a green LEDoS module is disposed on the upper or lower surface of the sighting housing between the dichroic mirror and the collimator lens, and a red LED array is formed on the inner surface of the side of the sighting housing between the dichroic mirror and the side of the sighting housing.

[0027] The aiming system of the present invention preferably includes a mechanical windowing driver and an elevation driver to combine electronic aiming point correction and mechanical aiming point correction. Effects of the invention

[0029] According to the aiming system of the present invention that provides an electronic zeroing correction function and HUD information, a red light aiming point and various sensing information of green light are generated from separate light sources and synthesized through a dichroic mirror and a collimator lens to be displayed to the user in the form of HUD information, thereby having the effect of simultaneously securing clarity of target aiming and efficiency of information transmission.

[0030] According to the present invention, the aiming point is adjusted by electronically changing the pixel position of a red LED array, so the resolution of zero point correction is greatly improved to 0.01 MOA or less, enabling precise and fine zeroing, and has the effect of preventing the zero point from being mechanically misaligned due to external shock or repeated zero point adjustment.

[0031] According to the present invention, by providing the user with HUD information automatically generated based on various sensor information (distance, wind direction, wind speed, temperature, etc.) along with a aiming point, the usability is increased in various shooting situations.

[0032] According to the present invention, by adopting an electronic zeroing correction function, the mechanical zeroing adjustment range of the sight is reduced, thereby ensuring the mechanical durability and lightweighting of the sight, and providing the effect of simplifying the manufacturing process and reducing manufacturing costs.

[0033] According to the present invention, when power is reapplied to the aiming system, the zeroing correction value stored in the non-volatile memory is automatically retrieved and applied, thereby eliminating the need for the user to readjust the zeroing every time, which increases user convenience.

[0034] The effects of the present invention are not limited to those mentioned above, and other unmentioned problems will be clearly understood by those skilled in the art from the description below. Brief explanation of the drawing

Specific details for implementing the invention

[0037] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the present invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention. Accordingly, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical spirit of the present invention; therefore, it should be understood that various equivalents and modifications capable of replacing them may exist at the time of filing this application.

[0038] The present invention relates to a red dot sight system that combines an electronic zeroing correction function based on an LED array with microdisplay-based HUD information. It controls the lighting pattern of multiple pixels of an LED array (110) through an MCU (230) and an LED controller (240) to finely move and correct the aiming point and stores the correction value in a non-volatile memory. It also provides precise zeroing correction and shooting assistance functions by optically synthesizing sensing information from multiple sensors through a dichroic mirror (140) and a collimator lens (130), and projecting it to the user as information in the form of a HUD.

[0039] The present invention is designed based on the idea that a clear aiming point (Red dot) is provided through a high-brightness red LED array (110) and various sensing information is provided through a green LEDoS module (120), and by synthesizing and displaying light sources of different wavelengths (red / green), the user can perform aiming and information acquisition simultaneously, and the zero point of the aiming point can be electronically adjusted by changing the pixel lighting position of the red LED array (110) without moving a mechanical lens.

[0040] Figure 1 is an example of a sighting system according to the prior art.

[0041] Referring to FIG. 1, the light from a single LED light source (111) formed on one side of the sight housing (100) is changed to infinity focus through a collimating lens (130) and projected onto a front reflective lens (150) to display the zeroing point when the user aims at a target.

[0042] In addition, in the case of conventional technology, the zero point is generally set through mechanical adjustment. That is, the position of a single LED light source (111) is adjusted horizontally (Windage) and vertically (Elevation) through a mechanical driving device or mechanical system to set the zero point. The zero point adjustment in such mechanical adjustment includes barrel deviation, mount error, and sight assembly error.

[0043] Meanwhile, regarding conventional mechanical adjustment methods, a range of ±50 MOA and a resolution of ±0.5 MOA per click is considered to be a very excellent product.

[0044] Existing dot sight aiming systems have limitations such as a limited adjustment range due to barrel deviation, mounting error, and sight assembly error, difficulty in fine correction due to the limit of mechanical resolution (e.g., about 0.5 MOA), potential for the barrel axis to become misaligned during repeated adjustments, and the aiming point being displayed as only a single point, which cannot provide external information such as wind direction, temperature, and distance.

[0045] Therefore, to solve these problems, there is a need for an aiming point system capable of providing electronic zeroing correction and external information in the form of a HUD, rather than mechanical zeroing correction.

[0046] FIG. 2 is an exemplary diagram of a sighting system according to an embodiment of the present invention.

[0047] The present invention relates to the fields of optical sights, micro-LED-based display technology, and optical synthesis technology, and to a sighting system that integrates LED array-based electronic aiming point movement and micro-display-based HUD information into a single optical system.

[0048] The present invention comprises a red LED array (110) disposed on the inner surface of one side of a sighting housing (100), including a plurality of red LED pixels, and outputting red light to form a sighting point; a green LEDoS module (120) disposed on the upper inner surface or lower inner surface of the sighting housing (100) and outputting sensing information output from a plurality of sensors (220) as green light; and an optical module (120, 130, 150) that combines the red light of the red LED array and the green light of the green LEDoS module and displays it to a user.

[0049] Referring to FIG. 2, the sight housing may have a cylindrical shape or a rectangular cross-section, and for convenience of explanation, the upper housing and the right housing are omitted.

[0050] The red LED array (110) of the present invention is composed of a plurality of LED pixels and performs the function of forming a reticle by outputting red light. The red LED array (110) has a pixel structure of a 32×32 array or a 64 X 64 array, preferably a pixel structure of a 32×32 array, and the pitch of each pixel is preferably formed to be 20 µm within the range of 15 to 25 µm to enable the formation of a precise reticle.

[0051] The above green LEDoS module (120) can be placed on the upper inner surface or lower inner surface of the sight housing (100) and generates a Head Up Display (HUD) image of various environmental information acquired through a plurality of sensors (220) and outputs it as green light.

[0052] The above green LEDoS module (120) is manufactured using LEDoS (LED on Silicon) fabrication technology and can be formed by depositing ultra-small micro LED chips on a silicon (Si) wafer substrate. That is, the above green LEDoS module (120) utilizes a silicon wafer-based backplane, uses inorganic-based micro LEDs as light-emitting elements, and can place ultra-small chips with pixel sizes of 5 to 20 μm on a silicon substrate in a transfer manner.

[0053] As such, the above green LEDoS module (120) can achieve an ultra-high pixel density of 5,000 to 7,000 PPI or more thanks to the precise driving circuit of the silicon substrate, thereby providing a clear image, and can achieve ultra-high brightness that can be seen clearly even outdoors thanks to the high luminous efficiency of the inorganic-based LED. This can be advantageously applied to a sighting system equipped with a HUD function that requires overlapping real light and virtual information.

[0054] Furthermore, the green LEDoS module (120) of the present invention has the advantage that the green LED pixels emit light themselves, so a backlight or color filter is not required, and by using an inorganic material (InGaN series), the burn-in phenomenon or degradation problem, which is a disadvantage of OLED, is reduced, and the response time is very fast in the nanosecond (ns) range, so a clear screen can be realized without afterimages, and the chip size can be reduced to the level of a few μm, thereby enabling the realization of an ultra-compact and high-resolution display.

[0055] In the present invention, the optical module performs the function of synthesizing red light and green light emitted from different locations into a single path and transmitting them to the user's eye. That is, the optical module (120, 130, 150) performs the function of synthesizing the red light of the red LED array (111) and the green light of the green LEDoS module (120) and displaying them to the user.

[0056] The optical module is configured to include a dichroic mirror (140), a collimator lens (130), and a front reflective lens (150).

[0057] The above dichroic mirror (140) performs the function of transmitting red light from the red LED array (110) and reflecting green light from the green LEDoS module (120), and is positioned between the red LED array (110) and the collimator lens (130) with respect to the side of the sight housing (100).

[0058] That is, a green LEDoS module (120) is placed on the upper or lower surface of the sight housing (100) between the dichroic mirror (140) and the collimator lens (130), and a red LED array (110) is placed on the inner surface of the side of the sight housing between the dichroic mirror (140) and the side of the sight housing (100).

[0059] When the green LEDoS module (120) is placed on the lower surface of the sight housing (100), the dichroic mirror (140) is inserted so as to be positioned obliquely from the upper right side to the lower left side of the sight housing, as shown in FIG. 2; and when the green LEDoS module (120) is placed on the upper surface of the sight housing (100), the dichroic mirror (140) is inserted so as to be positioned obliquely from the upper left side to the lower right side of the sight housing, contrary to what is shown in FIG. 2.

[0060] Of course, as can be seen in FIG. 2, the dichroic mirror (140) should be positioned so that the green light of the green LEDoS module (120) is reflected at the point of transmission of the red light of the red LED array (110), and the angle (θ) formed between the dichroic mirror (140) and the upper or lower surface of the sight housing (100) can be preferably formed at 45 degrees within the range of 40 to 50 degrees.

[0061] In this way, the dichroic mirror (140) transmits the red light from the red LED array (110) coming from the side and reflects the green light from the green LEDoS module (120) emitted from the top or bottom, thereby aligning the two light paths and enabling efficient synthesis of two light sources within the sight housing.

[0062] The dichroic mirror (140) of the present invention performs the function of selectively reflecting or transmitting light depending on the wavelength and is formed by coating multiple layers of dielectric thin films with different refractive indices on a glass substrate, and by utilizing the optical interference effect that occurs as light passes through the thin dielectric thin film layers, it reflects only light of a specific wavelength band and transmits light of the remaining wavelength bands.

[0063] That is, the dichroic mirror (140) is formed as a multilayer dielectric coating structure by precisely and alternately depositing thin films of dielectric materials with different refractive indices from tens to hundreds of layers on a transparent substrate, and light passing through or reflected from these thin film layers interacts with light reflected from the boundary surface of each layer and causes an interference effect.

[0064] The dichroic mirror (140) of the present invention is designed to reflect a specified wavelength band (e.g., short wavelength) and transmit another band (e.g., long wavelength). By precisely designing the thickness and refractive index of the coating layer, it can be formed so that the reflected waves cause constructive interference in the desired wavelength band and the transmitted waves cause constructive interference in the remaining wavelength band.

[0065] In the present invention, the red light emitted from the red LED array (110) can be set to have a wavelength value in the range of 630 nm to 660 nm, and the green light emitted from the green LEDoS module (120) can be set to have a wavelength value in the range of 520 nm to 550 nm.

[0066] Meanwhile, the dichroic mirror (140) must have a certain slope, i.e., a transition region, formed where it changes from reflection to transmission, and a cutoff wavelength (λ) between the wavelengths of the two light sources. C ) must be positioned. Accordingly, among the dielectric thin film layers of the dichroic mirror (140), a blocking wavelength layer (not shown) that allows only light with a wavelength of 570 nm to 600 nm to pass through can be formed, and when such a blocking wavelength layer is formed, green light of 550 nm or less is reflected, and red light of 620 nm or more is transmitted without loss.

[0067] Since the above dichroic mirror (140) reflects or transmits most of the light, the light absorption rate is very low, which is very advantageous for application in high-power light source systems as it generates less heat and minimizes signal loss, and in particular, as the incident angle of the light source increases, a blueshift phenomenon occurs in which the separated wavelength (transition wavelength) shifts toward a shorter wavelength. This can be utilized for fine adjustment of the aiming point, etc.

[0068] Also, since the dichroic mirror (140) must reflect the green light of the green LEDoS module (120) in parallel, it is preferable that it be positioned at a 45° angle with the lower surface of the sight housing (100).

[0069] The above-mentioned collimator lens (130) performs the function of projecting the composite light of the red light and green light onto the front reflective lens. Additionally, the above-mentioned collimator lens (130) performs the function of eliminating or significantly reducing the divergence of the red light and green light to align the light rays so that they travel in the same direction.

[0070] The above collimator lens (130) converts the combined light into infinitely focused parallel light and projects it, which allows the user to clearly see the aiming point of the red light and the HUD information of the green light even when the user's eyes are focused on the target.

[0071] That is, the collimator lens (130) of the present invention is used to convert diverging or converging light rays into collimated light rays, and when a point light source is placed at the focal point of the lens, the diverging light passing through the lens is changed into a collimated light ray.

[0072] As such, the collimator lens (130) of the present invention generates a light beam having high parallelism and a low divergence angle, and can precisely control the direction and focus of the light within the optical module.

[0073] Therefore, if the light source of the red LED array (110) or green LEDoS module (120) is accurately positioned at the focal point of the collimator lens, the light emitted from the light source travels parallel as it passes through the lens.

[0074] The beam passing through the collimator lens (130) has a very small or nearly zero beam divergence, so divergence or loss is minimized during the movement of light, thereby ensuring consistent directionality of the composite light of red and green light. The collimator lens can make light from a nearby light source parallel and produce the effect of projecting it as if it were coming from infinity.

[0075] The above-mentioned collimator lens (130) is a key element that determines the precision and beam quality of the system, and appropriate focal length, material (e.g., ZnSe) and lens shape must be selected according to the application and characteristics of the light source. In the present invention, an aspheric collimator lens can be applied to reduce spherical aberration and make the composite light parallel with high precision for precise synthesis of red light and green light.

[0076] The above-mentioned front reflective lens (150) is positioned so that a user can observe from the upper side of the sight housing (100), and performs the function of reflecting the composite light of red light and green light projected from the collimator lens (130).

[0077] The above-mentioned front reflective lens (150) can be selected from a concave lens, an aspherical lens, or a freeform lens, and performs the function of superimposing an external target, aiming point, and sensing information to display them to the user.

[0078] FIG. 2 shows red light and green light reflected from the front reflective lens (150) being projected directly onto the user, but depending on the needs of the invention, a glass (not shown) placed horizontally between the user and the front reflective lens (150) may also be provided.

[0079] The above glass may be inserted and positioned parallel to the upper surface of the sight housing (100) by removing a portion of the upper part of the sight housing (100).

[0080] FIG. 3 is a partial block diagram of a sighting system according to an embodiment of the present invention.

[0081] FIG. 3 shows the components of a part that controls a red LED array (110) and a green LEDoS module (120).

[0082] The control part of the aiming sight system of the present invention may be configured to include a horizontal / vertical adjustment unit (210), a plurality of sensors (220), a non-volatile memory (250), an MCU (230), and an LED controller (240).

[0083] The above MCU (230) receives input values ​​for horizontal adjustment (Windage) and vertical adjustment (Elevation) of the aiming point received from the horizontal / vertical adjustment unit (210), and sensing information from multiple sensors (220), and performs the function of controlling the LED controller.

[0084] And the LED controller (240) performs the function of controlling the lighting of individual pixels of the red LED array (110) according to the horizontal adjustment (Windage) and vertical adjustment (Elevation) input values ​​to electronically move the aiming point (300), and controlling the output of the green LEDoS module (120) based on the sensing information.

[0085] In relation to the electronic zeroing function of the present invention, the MCU (230) receives horizontal and vertical adjustment input values ​​from the user and controls the LED controller (240) according to these input values ​​to change the position of the pixels lit within the red LED array (110) (see FIG. 4).

[0086] For example, if the user performs a shooting test and the aiming point (300) is to the left of the point of impact, the user inputs a horizontal adjustment input value to the horizontal / vertical adjustment unit (210), and accordingly turns off the lights of the previously lit pixels and lights up the pixels located to the right.

[0087] In this way, when the position of the light source (pixel position) of the red LED array (110) changes, the position of the projected aiming point (300) changes, and as a result, the aiming point (300) moves along the XY axis. That is, the MCU (230) calculates the amount of movement ΔX and Δ based on the user's horizontal adjustment / vertical adjustment input values ​​and transmits them to the LED controller (240), and the LED controller (240) performs the movement of the aiming point by changing the lighting combination of the pixels of the red LED array (110).

[0088] And, the correction value or position value of the corrected aiming point is stored in a non-volatile memory (250) such as an EEPROM or flash memory. Therefore, even if the power of the aiming system is turned off and on, the MCU (230) can read the correction value or position value of the aiming point stored in the non-volatile memory (250) and automatically light up the pixels of the previously set red LED array (110) to maintain the zero point.

[0089] In the present invention, the plurality of sensors (220) include a distance measuring sensor, a barometric pressure sensor, a temperature sensor, and a gyro sensor mounted on the outer surface of the sight housing (100). Depending on the needs of the invention, the plurality of sensors (220) may be mounted on a firearm rather than on the outer surface of the sight housing (100).

[0090] Sensing information generated from the plurality of sensors (220) is input to the MCU (230), and the MCU (230) transmits a type of HUD rendering command to the LED controller (240) based on the received sensing information. The LED controller (240) drives the green LEDoS module (120) to display sensing information, such as distance, wind direction, wind speed, temperature, and gun posture (leveling, etc.), to the user in the form of a HUD.

[0091] That is, sensing information such as wind direction / wind speed, temperature, altitude, distance, and gun stance obtained from multiple sensors (220) is displayed as green light through the green LEDoS module (120), and can be said to be optically combined with a sighting point formed by red light and provided to the user.

[0092] Meanwhile, depending on the needs of the invention, the present invention may further include a mechanical windowing driver and an elevation driver, and may use mechanical zero point correction and electronic zero point correction in combination or complementarily.

[0093] For example, the above mechanical zeroing and electronic zeroing are used in combination: i) first, the user adjusts the mechanical horizontal / vertical adjustment driver to set the initial zeroing, and ii) when the user performs a shooting test and inputs the electronic horizontal / vertical adjustment input value for the error with the target, the MCU (230) transmits the electronic horizontal / vertical adjustment input value to the LED controller (240) to change the pixel lighting combination of the red LED array (110), thereby electronically fine-correcting the aiming point to set the final zeroing.

[0094] FIG. 4 is an example diagram showing how the aiming point is changed electronically according to an embodiment of the present invention.

[0095] As described above, the red LED array (110) can selectively light up a specific pixel or multiple pixels within the LED array to form a target point (300), and can move the target point based on the X-axis and Y-axis according to the change in the lighting pattern between pixels.

[0096] The above red LED array (110) may have a pixel structure of a 32×32 array or a 64 X 64 array, and the pixel pitch of the red LED array may be formed within the range of 15 to 25 µm.

[0097] As an example of the process of correcting the aiming point, first, the barrel deviation, mount error, and sight assembly error can be electronically adjusted according to the needs of the invention. Then, after the user's shooting test, when the horizontal adjustment / vertical adjustment input value is entered through a terminal or touch display attached to the gun, the horizontal adjustment / vertical adjustment input value is transmitted to the MCU (230), and the MCU (230) controls the LED controller (240) to adjust the pixel lighting position of the red LED array (110), and the zeroing correction value is stored in the non-volatile memory (250).

[0098] FIG. 4 illustrates red pixels (A) forming an existing aiming point and, in contrast, red pixels (A') that are illuminated by moving along the x-axis and y-axis with the correction value of the zero point reflected.

[0099] Meanwhile, we will examine the improved correction range and resolution of the aiming system of the present invention compared to existing systems.

[0100] First, assume that the red LED array (110) has a 32x32 pixel array structure and a 20um pixel pitch, and that the distance (f) from the red LED array (110) to the collimated lens (130) is 'f=20mm'.

[0101] And, when the pixel LED of the red LED array (110) moves by Δx with respect to the x-axis in the focal plane, the angle movement θ in the field of view is approximately 'θ It is. Here, '1 MOA Since it is 0.0002909 rad', ' (1MOA) = f 0.0002909' and since 'f = 20mm', ' (1MOA) It is calculated as = 5.8um.

[0102] Ultimately, in the red LED array (110) of the present invention, a 20 µm pixel shift can be adjusted by 3.44 MOA.

[0103] Accordingly, if the red LED array (110) has a resolution of a 32x32 pixel array structure and a pixel pitch of 20um, and the distance from the red LED array (110) to the collimating lens (130) is 20mm, the correction range can be said to be ±55MOA and the resolution ±3.44MOA.

[0104] Meanwhile, the aiming system of the present invention may further include a mechanical horizontal adjustment driver (not shown) and a vertical adjustment driver (not shown) to use electronic aiming point correction and mechanical aiming point correction in combination.

[0105] In this way, the correction range and resolution of the existing mechanical sight system and the sight system of the present invention are compared and summarized as shown in Table 1 below.

[0106] Correction range Resolution mechanical ±50 MOA ±0.5 MOA Mechanical + electronic electronic ±55 MOA ±3.44 MOA mechanical ±10 MOA ±0.1 MOA

[0107] As shown in the table above, the correction range of a conventional mechanical sight system is ±50 MOA, and in the case of the present invention, which combines mechanical and electronic correction, the correction range is wider at ±55 MOA, and it can be confirmed that it is improved compared to the correction range of a conventional mechanical sight system. That is, even when combining mechanical and electronic correction, the electronic correction alone in the present invention is sufficient to cover the correction range of the conventional mechanical correction, and the correction range of the mechanical correction can be drastically reduced.

[0108] In addition, as mentioned above, in the case of conventional mechanical sighting systems, a resolution of about ±0.5 MOA was considered excellent, but in the case of the present invention, a resolution of ±3.44 MOA is secured even with only electronic correction, so there is an advantage that a much clearer and higher-resolution aiming point can be formed.

[0109] FIG. 5 is an example diagram showing how a targeting point, etc. is displayed to a user according to the prior art and an embodiment of the present invention.

[0110] As described above, the plurality of sensors (220) of the present invention include a distance measuring sensor, a barometric pressure sensor, a temperature sensor, and a gyro sensor mounted on the outer surface of the sight housing or on the firearm, and the sensing information of the plurality of sensors is converted into distance to a target, wind direction, wind speed, temperature, or firearm attitude information by the green LEDoS module (120) and output in the form of a HUD so as to be displayed to the user.

[0111] FIG. 5(a) shows a sighting point formed on a target by a conventional sighting system, and FIG. 5(b) shows a sighting point (300) of red light and information, temperature, and wind direction / wind speed information of the target in green light being displayed by the sighting system of the present invention.

[0112] The user can make more precise shots by referring not only to the aiming point but also to information about the target, temperature, and wind direction / speed information.

[0113] Meanwhile, the present invention may be configured such that, depending on the needs of the invention, a camera (not shown) is attached to the barrel of a firearm to detect a target, and the image of the camera containing the target is projected through a collimator lens and a front reflector lens so that a user can observe it.

[0114] The present invention enables the implementation of a precise zeroing correction function through electronic aiming point movement based on an LED array, provides additional information to the user by projecting HUD information about the external environment onto a single optical system along with the aiming point, minimizes mechanical play and improves zeroing retention during repeated movements, and enables the implementation of storage and automatic recovery functions for electronic zeroing correction values.

[0115] As such, the present invention has the advantage of providing a next-generation aiming system that is precise, highly durable, and provides various information in a HUD format through red / green dual light sources and electronic pixel control.

[0116] Although the present invention has been described above in relation to specific embodiments, this is merely illustrative and the present invention is not limited thereto. A person skilled in the art to which the present invention pertains may change or modify the described embodiments without departing from the scope of the present invention, and various modifications and variations are possible within the scope of the technical spirit of the present invention and the equivalent scope of the claims set forth below.
