Description

Technical Field

[0001] This application relates to the technical field of optical imaging devices, and in particular to an optical component and a sighting scope. Background Art

[0002] With the development of thermal imaging technology, the application of multi-light fusion sighting scopes such as infrared combined with red dot and holographic is becoming more and more widespread. Currently, common multi-light fusions include the fusion of reflective red dot and infrared, and the fusion of digital and infrared. However, both of these fusion methods have certain defects. For example, the fusion method of reflective red dot and infrared cannot solve the inherent distortion problem of traditional red dot sighting scopes, and parallax is likely to occur at the edge of the field of view, affecting the accuracy of aiming. Although the fusion method of digital and infrared can solve the distortion problem through optical design, the screen and its driving circuit will generate relatively large power consumption, affecting the battery life of the whole machine. In addition, the brightness limitation of the screen reticle makes it difficult to adapt to applications in strong light environments. Summary of the Invention

[0041] Please refer to Figure 1 and Figure 2 , the optical component 1 of the embodiment of this application includes a first imaging component 11, a second imaging component 12, and a prism group 13.

[0042] As Figures 3 to 5 shown, the prism group 13 is a cuboid with a square cross-section. The prism group 13 is provided with a first diagonal plane 135 and a second diagonal plane 136 along the two diagonal directions of the cross-section. A first reflection film (not shown) is provided on the first diagonal plane 135, and a second reflection film (not shown) is provided on the second diagonal plane 136.

[0043] The first imaging component 11 is used to present a first image, the second imaging component 12 is used to present a second image. The first imaging component 11 and the second imaging component 12 are respectively located on opposite sides of the prism group 13, and the prism group 13 is used to reflect the first image through the first reflection film and reflect the second image through the second reflection film, so that the first image and the second image are fused to form a first fused image.

[0044] Specifically, in this embodiment, the prism group 13 is evenly divided into 4 prism units along the first diagonal plane 135 and the second diagonal plane 136, which are the first prism unit 131, the second prism unit 132, the third prism unit 133, and the fourth prism unit 134 in sequence. The plane where one right-angled side of the first prism unit 131 is located and the plane where one right-angled side of the second prism unit 132 is located together form the first diagonal plane 135, and the plane where the other right-angled side of the first prism unit 131 is located and the plane where one right-angled side of the fourth prism unit 134 is located together form the second diagonal plane 136.

[0045] That is to say, four isosceles right triangular prisms are jointly assembled to form a cuboid-shaped prism group 13, and the first prism unit 131, the second prism unit 132, the third prism unit 133, and the fourth prism unit 134 are connected end to end in sequence along the circumferential direction of the cross-section of the prism group 13. The plane where the right-angled sides adjacent to each other between the first prism unit 131 and the fourth prism unit 134, and the plane where the right-angled sides adjacent to each other between the second prism unit 132 and the third prism unit 133 together form the first diagonal plane 135; the plane where the right-angled sides adjacent to each other between the first prism unit 131 and the second prism unit 132, and the plane where the right-angled sides adjacent to each other between the fourth prism unit 134 and the third prism unit 133 together form the second diagonal plane 136.

[0046] The first imaging component 11 presents the first image at the first position 17, and the second imaging component 12 presents the second image at the second position 18. The first position 17 and the second position 18 are respectively located on the central axis L of the prism group 13 and on the opposite sides of the prism group 13. The central axis L is respectively perpendicular to the hypotenuse planes of the second prism unit 132 and the fourth prism unit 134, and the central axis L passes through the intersection point of the two diagonals of the cross-section. The first imaging component 11 and the second imaging component 12 are respectively located on the opposite sides of the prism group 13, which can facilitate the structural layout of the components, make the structure more compact, and reduce the occupied space. The first imaging component 11 and the second imaging component 12 are respectively arranged on the central axis L to maintain the consistency of the optical axis and prevent the images observed by the human eye from not being in the center.

[0047] The central axis L here refers to the virtual straight line perpendicular to the two outer side walls of the second prism unit 132 and the fourth prism unit 134, and the central axis L passes through the center point of the square cross-section. The first position 17 and the second position 18 are respectively located on the central axis L on both sides of the prism group 13, and can be symmetrically or asymmetrically arranged relative to the center point of the cross-section.

[0048] Such as Figure 2As shown, the first imaging component 11 can be, for example, an infrared imaging component. The infrared imaging component includes an infrared objective lens 112, an infrared detector 113, and a display screen 111. The infrared objective lens 112 is arranged on the side close to the target object and is used to form an access channel for the infrared radiation of the target object. The infrared detector 113 is used to convert the infrared radiation signal incident from the target object into an electrical signal and output it. The display screen 111 is arranged at the first position 17 and is used to receive the electrical signal transmitted by the infrared detector 113 to form a first image. The infrared imaging component can capture heat source targets in night, dark, and smoky environments and image the heat source targets onto the display screen 111. Specifically, the infrared detector 113 is a non-cooled vanadium oxide detector. The vanadium oxide detector has the advantages of high sensitivity, low noise, good image non-uniformity, and low cost of the imaging system.

[0049] Alternatively, the first imaging component 11 can also be a low-light imaging component (not shown). The low-light imaging component includes a visible light objective lens, a low-light detector, and a display screen 111. The display screen 111 is arranged at the first position 17 and is used to receive the electrical signal transmitted by the low-light detector to form a first image. The low-light imaging component can achieve aiming in low-light environments.

[0050] The second imaging component 12 is a reticle component, including a light source (not shown) and a reticle (not shown). A reticle pattern is provided on the reticle, and the light source is used to illuminate the reticle pattern to form a second image.

[0051] Specifically, in this embodiment, the display screen 111 is a high-brightness green screen or a high-brightness blue screen, preferably a high-brightness green screen. The light source is a red dot LED. The first reflective film is a green light reflective film or a blue light reflective film corresponding to the color of the display screen 111, and the second reflective film is a red light reflective film.

[0052] The working brightness of the high-brightness green screen or high-brightness blue screen in this embodiment needs to be greater than 1500 cd / m 2 , its resolution can be 800×600 pixels, and the pixel size can be: 15×15 μm 2 , and the working power consumption can be less than 80 mW. When the first imaging component 11 is an infrared imaging component, the thermal radiation from the target is imaged onto the infrared detector 113 through the infrared objective lens 112. The infrared detector 113 converts the thermal radiation into an electrical signal. After passing through the integration circuit and FPGA image processing, an infrared image (the first image) is presented on the high-brightness green screen. The high-brightness green screen is preferred here because the human eye is most sensitive to yellow and green light. Under the same visual intensity, the high-brightness green screen can minimize the power consumption of the screen, thereby increasing the continuous operation time of the entire aiming scope. On the other hand, the high-brightness green screen has a high working brightness, can adapt to the light intensity loss of the splitting optical path, and can also have excellent performance in strong light daytime environments, meeting the requirements of day and night operation.

[0053] The green light reflecting film only reflects the green light incident on its surface. Similarly, the blue light reflecting film only reflects the blue light incident on its surface, which will not change the propagation direction of the red light of the second image and will not cause loss of the light intensity of the red light. Similarly, the red light reflecting film only reflects the red light incident on its surface, which will not change the propagation direction of the green light of the first image and will not cause loss of the light intensity of the green light. The selected green light reflecting film and red light reflecting film have an average reflectivity higher than 99% in a specific wavelength band, reducing the light intensity loss during the beam combination of the two beams of light and making the aiming scope system have a higher light efficiency. The red light reflecting film and the green light reflecting film (blue light reflecting film) in this embodiment are both dichroic films, which divide the light beam into transmitted light and reflected light according to the wavelength. Taking the green light reflecting film as an example, a long-wave pass dichroic film with a starting wavelength of 550 nm can be selected. In this way, the green light in the wavelength band of 492 - 550 nm is reflected at this reflecting film, and the light with a wavelength greater than 550 nm is refracted at this reflecting film.

[0054] The reticle pattern for forming the second image can have various styles. For example, it can include two reticle patterns of a circle and a dot. Corresponding circular and dot-shaped hollow patterns are respectively formed on the reticle plate. Two red dot LEDs are respectively placed below the dot and the circle on the reticle plate. When one red dot LED is on, a dot-shaped reticle is presented; when the other red dot LED is on, a circular reticle is presented; when both red dot LEDs are on simultaneously, a dot and circular reticle is presented, so that different reticle styles are presented in the second image. The circular reticle, in combination with the field of view angle of the collimating lens group 16, can be used to estimate the target distance. By controlling the brightness of the red dot LED, the red dot reticle of the second image can adapt to different brightness environments and can maintain a relatively low average power consumption, thereby reducing the power consumption of the aiming scope and extending its working time.

[0055] As Figure 1 and Figure 2 shown, meniscus lenses 14 are respectively provided between the prism group 13 and the first position 17, and between the prism group 13 and the second position 18. The light rays emitted by the high-brightness green screen (first image) and the red dot reticle (second image) are incident on the corresponding reflecting films of the prism group 13 after passing through the meniscus lenses 14. The meniscus lenses 14 increase the front intercept of the collimating lens group 16, creating space for the installation of the prism group 13, which is beneficial to making the structure of the aiming scope more compact and the volume more small and exquisite.

[0056] The optical component 1 of this embodiment further includes a semi-transmissive and semi-reflective mirror 15 and a collimating lens group 16. The collimating lens group 16 is arranged outside the first prism unit 131, and the semi-transmissive and semi-reflective mirror 15 is arranged on the natural light incident light path, which is used to transmit natural light and reflect the collimated light of the first fused image after being collimated by the collimating lens group 16 to form a second fused image. The collimating lens group 16 can act as an eyepiece to expand the viewing angle of the first image on the observation screen, and can also eliminate aberration through optical design. Its adjustment magnification is 1 times, so that the first image is fused with the natural light image to achieve a better observation effect. At the same time, the collimation of the combined red and green light rays is realized, so that the virtual image formed by the superposition of the first image and the second image observed at the human eye end coincides with the natural light image formed by the real object in the distance, achieving the fusion and aiming effects.

[0057] Specifically, the optical component 1 of this embodiment can achieve triple-light fusion. The semi-transmissive and semi-reflective mirror 15 is arranged on the incident light path of natural light. After the natural light passes through the semi-transmissive and semi-reflective mirror 15, half of the light rays do not change the light direction and pass through the semi-transmissive and semi-reflective mirror 15 to form a natural light image. The semi-transmissive and semi-reflective mirror 15 is arranged parallel to the first diagonal plane 135 and is located above the collimating lens group 16 in the figure. After the first image and the second image form a first fused image at the prism group 13, their light rays are collimated by the collimating lens group 16 and then enter the semi-transmissive and semi-reflective mirror 15. Half of the light rays are reflected by the semi-transmissive mirror and fused with the natural light image to form a second fused image. The human eye can observe the second fused image of the heat source target at the exit pupil position of the aiming scope and can aim through the reticle pattern of the second image.

[0058] As Figure 2 、 Figure 6 and Figure 7 shown, the embodiment of the present application also provides an aiming scope, which includes the above-mentioned optical component 1, and also includes a housing (not shown), a glass window 3, a main control board 7, a first button 6 and a second button 9. The optical component 1 and the main control board 7 are respectively arranged in the housing. The housing is provided with a natural light incident light path, and the glass window 3 is arranged at both ends of the natural light incident light path. The first button 6 and the second button 9 are respectively arranged on the outer wall of the housing.

[0059] The main control board 7 is provided with a first controller (not shown) and a second controller (not shown); the first button 6 is used to control the opening and closing of the first imaging component 11 through the first controller or to adjust the brightness of the first image. For example, the image mode, brightness and contrast of the display screen 111 can be adjusted, and the opening and closing of photographing, video recording and WiFi can be manipulated to achieve wireless transmission

[0060] The second button 9 is used to control the opening and closing of the second imaging component 12 through the second controller or to adjust the brightness and style of the second image.

[0061] Specifically, the main control board 7 is also integrated with an FPGA chip for image processing, an SOC chip (the first controller) for controlling shooting, recording, storage, and wireless transmission, and an MCU chip (the second controller) for controlling the red dot LED. The brightness of the red dot LED can be controlled through the second button 9 and the second controller to meet the requirements of different brightness environments. Additionally, the on or off state of all or part of the red dot LEDs can be controlled to make the second image present different reticle patterns. The brightness of the high-brightness green screen can be controlled through the first button 6 and the first controller to adapt to different brightness environment requirements, minimizing power consumption without affecting the imaging effect. Alternatively, the first imaging component 11 can be controlled to turn off, making the sight form a single red dot state. At this time, the power consumption of the sight can be significantly reduced, and the battery life of the sight can be extended. When operating in the single red dot state, the infrared core of the infrared imaging component, the main control board 7, and the display screen 111 are all turned off, and only the red dot LED and the second controller are working. Therefore, extremely low power consumption can be maintained, thereby increasing the battery life of the sight.

[0062] The main control board 7 is also provided with a WiFi antenna 10 and a USB interface 4. The WiFi antenna 10 is used for receiving and transmitting wireless signals to achieve wireless data transmission, and the USB interface 4 is used for connecting to external devices to achieve functions such as data transmission and charging the entire machine.

[0063] The housing also contains a rechargeable battery 2. In this embodiment, an 18650 battery is selected to supply power to the entire machine. The rechargeable battery 2 is electrically connected to the main control board 7 and is detachably installed in the housing. This 18650 battery has the advantages of mature technology and large capacity.

[0064] The housing also contains a red dot adjustment mechanism 5. Before aiming the sight, the position of the red dot reticle needs to be adjusted up, down, left, and right through the red dot adjustment structure to make the center of the aiming point coincide with the bullet impact point on the target, achieving calibration and improving the aiming accuracy.

[0065] The bottom of the housing is also provided with a quick-release bracket 8, which is used for quick disassembly and assembly with the Picatinny rail. The quick-release bracket 8 in this embodiment is integrally designed with the bottom of the housing, effectively improving the space utilization rate and reducing the overall thickness of the sight and the height of the aiming baseline.

[0066] The ratio of the width to the length of the glass window 3 is 3:4. In this embodiment, the width of the glass window is not less than 25 mm, and the length of the glass window 3 is not less than 32 mm. The sight in this embodiment uses a relatively large glass window 3, which can increase the field of view angle of the sight. The glass window 3 can play a role in protection and sealing, allowing the human eye to observe and aim through the glass window 3.

[0067] The optical component and the sight provided by the embodiments of the present application are such that the green light emitted by the display screen and the red light emitted by the red dot LED are both reflected at the corresponding reflective films of the prism group, changing the optical path propagation direction, so that the first imaging component and the red dot adjustment mechanism can be arranged on both sides of the prism group. This layout conforms to the three-section layout of the sight, improving the space utilization rate. The light rays of the first fused image collimated by the collimating lens group 16 are fused again with the transmitted natural light image at the semi-transmissive and semi-reflective mirror 15 to form a second fused image (the image display content includes the natural light from the object, the first image at the display screen 111, and the second image of the red dot reticle) and enter the human eye. The first image and the second image achieve the purpose of eliminating aberration after multiple refractions by optical lenses with different curvatures, so there is a better fusion effect with the object at the semi-transmissive and semi-reflective mirror 15. And by using the combination of positive and negative lenses of the collimating lens group 16, the light rays at the edge of the lens can also approach ideal imaging, without parallax and distortion generated with the change of the human eye's observation position, effectively improving the aiming accuracy of the sight.

[0068] The optical component and the sight provided by the embodiments of the present application have the advantages of small size, light weight, large field of view, no parallax, high light efficiency, and long battery life. It uses an optical system to shape the first image and the second image, eliminating distortion and making the natural light image, the first image, and the second image achieve a better fusion effect. The prism group is provided with reflective films of specific colors, which realizes the fusion of the first image and the second image. The reflective films of specific colors only have high-efficiency reflection for the light rays of the corresponding colors, without causing energy loss of other color lights, so there is higher light efficiency. The collimating lens group realizes the collimation of the combined light rays, eliminating the parallax generated when observing from different angles of the sight and improving the aiming accuracy. The first imaging component and the red dot adjustment mechanism are located on the opposite side of the prism group. The optimized component layout compresses the volume and weight of this sight to the extreme, and this sight can be suitable for rapid aiming with flexible response in all-weather and multi-scene.

Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application.
