[0022] To more clearly illustrate the technical solutions of the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0023] Figure 1 It is a schematic structural diagram of a specific embodiment of the infrared sight provided by the present invention;

[0024] Figure 2 It is a schematic structural diagram of another specific embodiment of the infrared sight provided by the present invention.

[0025] In the figure, it includes 10 - differential reflector, 11 - infrared reflecting surface, 12 - visible light reflecting surface, 21 - front group infrared objective lens, 22 - rear group infrared objective lens, 31 - front group visible light eyepiece, 32 - rear group visible light eyepiece, 40 - infrared movement, 50 - micro display, 60 - observation end. Specific Embodiment

[0026] In order to enable those skilled in the art to better understand the solution of the present invention, the following will further elaborate on the present invention in combination with the drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] The core of the present invention is to provide an infrared sight. A schematic structural diagram of a specific embodiment thereof is as Figure 1 shown, which is called Specific Embodiment 1, and includes a differential reflector 10, an infrared objective lens group, a visible light eyepiece group, a micro display 50, and an infrared movement 40;

[0028] One surface of the differential reflector 10 is an infrared reflecting surface 11, and the other surface is a visible light reflecting surface 12;

[0029] External infrared rays pass through the infrared reflecting surface and the infrared objective lens group and enter the infrared movement 40;

[0030] The infrared movement 40 analyzes the received external infrared rays to obtain image data and sends the image data to the micro display 50;

[0031] The micro display 50 generates a visible light image according to the image data, and the visible light image reaches the observation end 60 through the visible light eyepiece group and the visible light reflecting surface 12.

[0032] The observation end 60 refers to the position where the user's human eye receives the visible light image.

[0033] Of course, the differential mirror 10 includes the infrared reflecting surface 11 and the visible light reflecting surface 12, but the differential mirror 10 may include more than just the above two surfaces. In other words, the differential mirror 10 may include two mirror surfaces or multiple mirror surfaces.

[0034] The infrared objective lens group may include multiple objective lenses, and different objective lenses may be arranged at different positions.

[0035] Specifically, the infrared objective lens group includes a front group infrared objective lens 21 and a rear group infrared objective lens 22;

[0036] The external infrared rays pass through the front group infrared objective lens 21, reach the infrared reflecting surface 11, are reflected by the infrared reflecting surface 11, pass through the rear group infrared objective lens 22, and reach the infrared core unit 40.

[0037] In this preferred embodiment, the infrared objective lens group is divided into two parts. The front group infrared objective lens 21 is arranged between the lens light inlet and the differential mirror 10, and is used to collect the infrared rays (i.e., the external infrared rays) in the scene and correct the aberration therein, so that it refracts onto the infrared reflecting surface 11 of the differential mirror 10. In addition, the rear group infrared objective lens 22 is arranged between the differential mirror 10 and the infrared core unit 40, and is used to correct the reflected aberration and converge the light onto the infrared core unit 40 for imaging.

[0038] As a preferred embodiment, the front group infrared objective lens 21 and / or the rear group infrared objective lens 22 is / are germanium lenses. The germanium lenses have a high transmittance for long-wave infrared rays, making the infrared image received by the infrared core unit 40 clearer.

[0039] Of course, the visible light eyepiece group may also include multiple eyepieces, and the multiple eyepieces are arranged at different positions. Specifically, the visible light eyepiece group includes a front group visible light eyepiece 31 and a rear group visible light eyepiece 32;

[0040] The infrared core unit 40 includes an infrared sensor and an image processor. The infrared sensor receives the converged infrared rays and forms an image thereof, and the image processor transmits the formed infrared image to the micro display 50 to display it in the form of visible light.

[0041] The visible light image passes through the front group visible light eyepiece 31, reaches the visible light reflecting surface 12, is reflected by the visible light reflecting surface 12, passes through the rear group visible light eyepiece 32, and reaches the observation end 60.

[0042] The front group of visible light eyepieces 31 is arranged between the microdisplay 50 and the visible light reflecting surface 12 of the differential mirror 10, and is used to correct the visible light aberration of the screen of the microdisplay 50 and refract the light onto the differential mirror 10. The rear group of visible light eyepieces 32 is arranged between the differential mirror 10 and the observation end 60, and is used to correct the aberration of the reflected light and project the light to the observation end 60 in the form of parallel light.

[0043] Furthermore, at least one of the front group of visible light eyepieces 31 and / or the rear group of visible light eyepieces 32 is a glass lens and / or a plastic lens. The glass lens has high hardness, good light transmittance, is not easily deformed, and has high working stability. The plastic lens is lightweight, which is beneficial to the lightweight of the aiming mirror and can be selected according to the actual situation. Of course, other types of lenses can also be selected, and the present invention does not limit this here.

[0044] Furthermore, the incident angles of the external infrared rays and the visible light image entering the differential mirror 10 are both 45 degrees. The incident angles of the two kinds of light rays entering the differential mirror 10 are both 45 degrees, that is, the incident directions and the outgoing directions of the two kinds of light rays are both perpendicular, which is equivalent to folding a part of the optical path to the vertical direction, further reducing the axial length of the infrared aiming mirror, being beneficial to the integration during this period, and reducing the volume of the infrared aiming mirror.

[0045] Furthermore, the incident light of the external infrared rays on the differential mirror 10 and the outgoing light of the visible light image reflected by the differential mirror 10 are on the same optical axis.

[0046] For reference Figure 1 , since the optical paths of the two kinds of light rays entering the differential mirror 10 and the optical paths of the two kinds of light rays exiting the differential mirror 10 are perpendicular to each other, and in this specific embodiment, it is further defined that the incident light of the external infrared rays on the differential mirror 10 and the outgoing light of the visible light image reflected by the differential mirror 10 are on the same optical axis, that is, on the same straight line. Therefore, the incident and outgoing light rays of the two kinds of light rays on the differential mirror 10 are arranged in a cross shape, greatly reducing the difficulty of the optical path design and simplifying the production process. It should be noted that Figure 1 The lens groups in

[0047] In addition, the differential mirror 10 is a plane mirror. As Figure 1 shown, the differential mirror 10 is a plane mirror, and the infrared reflecting surface 11 and the visible light reflecting surface 12 are the front and back sides of the plane mirror. The plane mirror occupies a small space, can further compress the space occupied by the infrared aiming mirror, and is beneficial to the miniaturization and integration of the device.

[0048] In addition, the micro display 50 is an LED display. The LED display has high brightness and small volume, taking into account both clear image display and small space occupation. Of course, other display components can also be used as the micro display 50, and the present invention does not limit this here.

[0049] The infrared aiming scope provided by the present invention includes a differential reflection mirror 10, an infrared objective lens group, a visible light eyepiece group, a micro display 50 and an infrared movement 40; one surface of the differential reflection mirror 10 is an infrared reflection surface 11, and the other surface is a visible light reflection surface 12; external infrared rays pass through the infrared reflection surface and the infrared objective lens group and enter the infrared movement 40; the infrared movement 40 analyzes the received external infrared rays to obtain image data and sends the image data to the micro display 50; the micro display 50 generates a visible light image according to the image data, and the visible light image passes through the visible light eyepiece group and the visible light reflection surface 12 to reach the observation end 60. In the present invention, the infrared objective lens optical path and the visible light eyepiece optical path share the differential reflection mirror 10, so that a part of the optical paths of the two systems propagate in a direction deviating from the direction of the incident external infrared rays, that is, the folding of the two optical paths is realized, greatly reducing the volume and weight of this infrared aiming scope system, improving the portability and reducing the burden on the user.

[0050] On the basis of the specific embodiment one, the differential reflection mirror 10 is further defined to obtain the specific embodiment two, and its structural schematic diagram is as Figure 2 shown, including a differential reflection mirror 10, an infrared objective lens group, a visible light eyepiece group, a micro display 50 and an infrared movement 40;

[0051] One surface of the differential reflection mirror 10 is an infrared reflection surface 11, and the other surface is a visible light reflection surface 12;

[0052] External infrared rays pass through the infrared reflection surface and the infrared objective lens group and enter the infrared movement 40;

[0053] The infrared movement 40 analyzes the received external infrared rays to obtain image data and sends the image data to the micro display 50;

[0054] The micro display 50 generates a visible light image according to the image data, and the visible light image passes through the visible light eyepiece group and the visible light reflection surface 12 to reach the observation end 60;

[0055] The differential reflection mirror 10 is a prism.

[0056] The difference between this specific embodiment and the above-mentioned specific embodiment lies in that in this specific embodiment, the shape of the differential mirror 10 is specifically defined, and the rest of the structure is the same as that of the above-mentioned specific embodiment, so it will not be elaborated here.

[0057] In this specific embodiment, the differential mirror 10 is defined as a prism mirror. Obviously, the infrared reflecting surface 11 and the visible light reflecting surface 12 are respectively the side mirrors of the prism, and the prism has at least three side mirrors, which makes there be spare side mirrors in the prism that can be used for other optical paths, greatly improving the expandability and compatibility of the infrared sight, and enhancing the versatility of the infrared sight provided by this specific embodiment. Figure 2 Only the structural schematic diagram of the prism as the differential mirror 10 and the incident light and outgoing light of two kinds of light are given, and for the rest of the structure, please refer to Figure 1 , and it will not be given again.

The same or similar parts among the various embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.
