[0041] In order to make the person skilled in the art better understand the technical solutions of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments. Among them, the terms "first", "second", "third", "fourth" and the like in the specification and the above-mentioned drawings are used to distinguish different objects, and are not used to describe a specific order.

[0042] The infrared-visible light fusion multi-light fusion system provides target image and accurate aiming reference in all-weather and extreme environmental conditions. The visible light channel and the infrared channel of the infrared-visible light fusion multi-light fusion system in the related art are two independent channels. For the infrared-visible light fusion multi-light fusion system with a common aperture, a prism or a lens is still needed to be used to split the beams into two separate channels of visible light and infrared, which makes the volume and weight of the entire optical system of the infrared-visible light fusion multi-light fusion system much higher than those of the infrared multi-light fusion system or the white light multi-light fusion system alone, increases the burden of the user, and the user experience is not good.

[0043] In view of this, the present application can realize the deployment of the infrared imaging system and the visible light imaging system on the same horizontal plane through the periscope system, that is, sinking the visible light imaging system in the existing infrared-visible light fusion multi-light fusion system to the infrared imaging system and applying it in the sighting telescope, thereby effectively reducing the weight and volume of the multi-light fusion system. After introducing the technical scheme of the present application, the various non-limiting embodiments of the present application will be described in detail below. In order to better illustrate the present application, numerous specific details are given in the specific embodiments below. Those skilled in the art should understand that the present application can also be implemented without these specific details. In some other examples, methods, means, elements and circuits familiar to those skilled in the art are not described in detail in order to highlight the main idea of the present application.

[0044] First, see Figure 1 , Figure 1 The multi-light fusion system provided by the embodiments of the present application can include the following contents:

[0045] The multi-light fusion system can include a periscope system 101, an infrared imaging system 102, a visible light imaging system 103 and a display 104.

[0046] Among them, the infrared imaging system 102 and the visible light imaging system 103 are located on the same optical axis, or the prism group of the visible light imaging system 103 is moved to the infrared imaging system 102, that is, the prism group on the visible light channel is moved to the infrared channel, thereby realizing the sinking of the visible light imaging system 103 to the infrared imaging system 102. The display 104 is conjugated with the image plane position of the reticle of the visible light imaging system 103; the reticle is engraved with a reticle pattern, for example, it can be composed of transparent glass material engraved with a reticle pattern, and the reticle is placed on the image plane of the visible light imaging system 103. Since the image plane is the object plane of the visible light objective system, the reticle pattern engraved on the reticle can be imaged, providing the user with an infinite reticle field of view, facilitating the user to aim at the target. The display 104 is conjugated with the image plane, so the display 104 is also the object plane of the visible light objective system, and the human eye can see the light emitted by the image plane and the display 104 at the same time.

[0047] When aiming at a target object using the sighting system, the visible light signal and the radiated infrared signal of the target object and its surroundings enter the sighting scope, the infrared signal enters the infrared imaging system 102, the infrared imaging system 102 performs infrared imaging on the received infrared light signal and converts the infrared image into a video signal and transmits the video signal to the display 104, and the display 104 displays the infrared image. The visible light signal enters the periscope system 101, and the periscope system 101 projects the received visible light signal of the target object to the visible light imaging system 103; the visible light imaging system 103 transmits the visible light signal and forms an erect target image of the target object on an image plane and a reticle image of a reticle pattern of a reticle plate located on the image plane, and the erect target image is the imaging of the erect target object. Finally, the infrared image light signal emitted by the display 104, the erect target image, and the reticle image are fused to form an image signal, and the image signal is emitted to the human eye.

[0048] As can be seen from the above, the periscope system 101 can be used to deploy the infrared imaging system 102 and the visible light imaging system 103 in the same horizontal plane, that is, to sink the existing visible light imaging system 103 in the infrared-visible light fusion sighting scope to the infrared imaging system 102. The application of the multi-light fusion system to the sighting scope can greatly reduce the height of the entire sighting scope in the vertical direction, thereby reducing the vertical volume of the sighting scope. Further, after the visible light imaging system 103 is sunk to the infrared imaging system 102, the number of visible light objectives used is reduced, thereby reducing the weight of the entire sighting scope.

[0049] The infrared channel and the white light channel in the infrared-visible light fusion sighting scope in the related art are usually two independent systems, and the systems are not coaxial, which results in a large volume of the entire system. In the embodiment, the periscope system 101 is used to sink the visible light imaging system 103 to the infrared imaging system 102, for example, the visible light imaging system 103 and the infrared imaging system 102 are located on the same optical axis. For example, the periscope system 101 in the above embodiment can include a first plane mirror and a second plane mirror; the first plane mirror reflects the visible light signal of the target object to the second plane mirror, and the second plane mirror reflects the reflected signal of the visible light signal to the visible light imaging system 103. In order to obtain good imaging effect and increase the light flux entering the periscope system 101, the first plane mirror and the second plane mirror are parallel, and the included angle between the first plane mirror and the second plane mirror and the infrared optical axis of the infrared imaging system 102 is 45°± a fluctuation value. The fluctuation value can be a small value caused by random factors.

[0050] As can be seen from the above, the periscope system 101 is used to sink the visible light imaging system 103 to the infrared imaging system 102, for example, the visible light imaging system 103 and the infrared imaging system 102 are located on the same optical axis. For example, the periscope system 101 in the above embodiment can include a first plane mirror and a second plane mirror; the first plane mirror reflects the visible light signal of the target object to the second plane mirror, and the second plane mirror reflects the reflected signal of the visible light signal to the visible light imaging system 103. In order to obtain good imaging effect and increase the light flux entering the periscope system 101, the first plane mirror and the second plane mirror are parallel, and the included angle between the first plane mirror and the second plane mirror and the infrared optical axis of the infrared imaging system 102 is 45°± a fluctuation value. The fluctuation value can be a small value caused by random factors.

[0051] The above embodiments do not make any limitation on the structure of the infrared imaging system 102 and the visible light imaging system 103. Based on the above embodiments, this embodiment further gives an illustrative implementation, which can include the following contents:

[0052] The infrared imaging system 102 can include an infrared objective lens group, an infrared sensor, and an image processor. The infrared objective lens group can include a single or multiple infrared objective lenses, each of which can be an optical component made of infrared materials such as germanium or silicon. Infrared light in the target object and background thermal radiation in the external scene enters the infrared objective lens group. The infrared objective lens group receives the external infrared light signal and performs imaging on the infrared light signal, corrects the aberration of the light, and makes the image converged on the sensor clear and sharp. The infrared imaging signal is projected to the infrared sensor. The infrared sensor can be a non-cooled detector composed of a temperature-sensitive thermistor unit or a cooled detector composed of a photosensitive material. The main function is to receive and store the electrical signal of the infrared image incident on the sensor. The infrared sensor receives the infrared image incident on the infrared sensor, converts the infrared image signal into an electrical signal for storage, and sends the electrical signal to the image sensor. The image sensor converts the electrical signal into a video signal. Illustratively, the image processor converts the electrical signal stored by the infrared sensor into a digital signal and converts the digital image signal into a video signal transmitted to the display screen 104.

[0053] The visible light imaging system 103 comprises a visible light imaging module, a reticle and a fusion light imaging module; the visible light imaging module converges the visible light signal from the periscope system 101 on a first image surface and forms an erect target image on the first image surface; the reticle is located on the first image surface and forms a reticle image on the first image surface; the fusion imaging module receives the infrared image light signal emitted by the display 104 and the visible light signal emitted by the first image surface, converts the infrared image light signal and the visible light signal into parallel light rays after propagation in the same direction, and emits the parallel light rays. The visible light imaging module comprises a visible light objective lens and a turning prism; the visible light objective lens can comprise a single piece of visible light glass material or multiple groups of visible light glass material; the multi-light fusion system of the embodiment does not need to be zoomed, so the number of lenses of the visible light objective lens is small, effectively reducing the weight of the entire optical system. The visible light objective lens receives the visible light signal projected by the periscope system 101 and corrects the aberration of the visible light, so that the image converging on the first image surface is clear and sharp. In the visible light imaging system 103, the light emitted by the object below the optical axis converges on the first image surface above the optical axis after passing through the visible light objective lens, that is, the light emitted by the object below the optical axis will form an inverted image on the first image surface after passing through the visible light objective lens. In order to facilitate the user to observe, the embodiment receives the light emitted by the visible light objective lens through the turning prism, and the light will be reflected multiple times in the prism, converting the inverted image into an erect image, that is, forming an erect target image on the first image surface. The fusion light imaging module comprises a half-transmission half-reflection prism and a visible light eyepiece; the display 104 is located above the half-transmission half-reflection prism, and the center distance between the display 104 and the half-transmission half-reflection prism is equal to the center distance between the first image surface and the half-transmission half-reflection prism. The half-transmission half-reflection prism is a square prism with a 45° half-transmission half-reflection surface, which receives the infrared image light signal emitted by the display 104 and the visible light signal emitted by the first image surface, reflects the infrared image light signal to the visible light eyepiece, and transmits the visible light signal to the visible light eyepiece. In other words, the half-transmission half-reflection prism reflects part of the light emitted by the display 104 incident to the half-transmission half-reflection surface, and transmits the light from the first image surface incident to the half-transmission half-reflection surface, so that the two beams of light incident in different directions propagate in the same direction after passing through the half-transmission half-reflection surface, so as to realize the fusion of the light. The visible light eyepiece is composed of a single piece or multiple pieces of visible light glass material, and images the visible light signal and the infrared image light signal, corrects the internal aberration, and emits parallel light rays at the exit pupil. The human eye can receive the light emitted by the entire optical system, including the image of the visible light system, the reticle image at infinity, the infrared image and other information in the display 104.

[0054] As can be seen from the above, the embodiment reasonably arranges the visible light and infrared channels, not only can realize observation in all-weather and complex environment, but also can reduce the weight and volume of the entire multi-light fusion system.

[0055] Finally, the application also provides a riflescope, please refer to Figure 2 The riflescope 200 can include the multi-light fusion system described in any of the above embodiments, that is, the riflescope 200 is made of the periscope system 101, the infrared imaging system 102, the visible light imaging system 103 and the display 104 of the multi-light fusion system based on the above embodiments. By being able to greatly reduce the height of the entire riflescope 200 in the longitudinal direction, and also reducing the number of visible light objectives used, the volume and weight of the entire riflescope 200 are reduced.

[0056] In order to further improve the practicability of the riflescope 200, meet more user needs, and improve the user experience, based on the above embodiments, the riflescope 200 of the application can also include a laser ranging system 105 for supporting detection of a long-distance target and obtaining distance data of the target, as shown in Figure 3 The laser ranging system 105 can include a laser range finder and a data transmission system; the data transmission system connects the laser range finder and the display 104. The laser range finder emits a laser signal to the target, and then the light reflected by the target enters the laser range finder and is received by the sensor thereof. By recording the time of laser emission and return, the distance between the target and the range finder can be obtained, and the target distance between the target and the laser range finder is obtained. The laser range finder generates the target distance between the target and the laser range finder, and transmits it to the display 104 through the data transmission system for display. Correspondingly, the visible light imaging system 103 also fuses the infrared image light signal and the distance light signal emitted by the display 104, the upright target image and the graticule image to form an image, so that the human eye receives the light emitted by the entire optical system, including the image of the visible light system, the infinite graticule image, the infrared image, the laser ranging information and other information in the miniature display 104.

[0057] Finally, in order to better understand the principles and ideas of the embodiments of the application, please refer to Figure 4 The application also provides a fusion white light, infrared and laser riflescope 200, which can include the following contents:

[0058] The sight 200 may include an infrared objective lens group 1, an infrared processor 2, a laser rangefinder system 105, a periscope system 101, a visible light objective lens 5, a transparent reticle 6, an image-rotating prism 7, a miniature display 104, a semi-transparent prism 9, and a visible light eyepiece 10. The infrared objective lens group 1, infrared processor 2, visible light objective lens 5, image-rotating prism 7, transparent reticle 6, semi-transparent prism 9, and visible light eyepiece 10 are coaxial. To optimize layout and reduce the size of the sight 200, the display 104 is placed close to the laser rangefinder system 105 and the infrared processor 2 to facilitate data transmission between them via shorter wiring. To further reduce vertical volume, the periscope system 101 can be positioned after and slightly above the infrared objective lens group 1 to allow sufficient light to enter.

[0059] Based on the aforementioned aiming scope 200, firstly, infrared light is converged onto the infrared sensor 2 by the infrared objective lenses of the infrared objective lens group 1. The image processor processes the data obtained from the infrared sensor 2 and transmits the infrared image to the display 104. The laser rangefinder 105 detects the target object and transmits the obtained distance and other data to the display 104. Visible light from the external scene is incident on the visible light objective lens 5 through a periscope structure composed of two reflectors. After passing through the visible light objective lens 5, the light converges at the first image plane, where there is a transparent reticle 7. After the light propagates from the first image plane to the image-rotating prism 7, it is transformed from an inverted image to an upright image. The light, along with the infrared image and ranging information emitted by the display 104, which is in a conjugate position with the first image plane, propagates to the semi-transparent and semi-reflective prism 9. The visible light passes through the semi-transparent and semi-reflective prism, and the light emitted by the display 104 is reflected by the semi-transparent and semi-reflective prism 9. After the two beams of light merge, they pass through the visible light eyepiece 10 and are emitted as parallel light to be received by the human eye.

[0060] As can be seen from the above, this embodiment provides a white light infrared laser ranging three-light fusion system, which can not only realize all-weather and complex environment observation, but also reduce the weight and volume of the entire optical system by reasonably arranging the visible light and infrared channels. With the addition of a laser ranging system, the user experience can be greatly improved.
