the display 22 is used for displaying a video output by the sight, the video information sent by the sight to the display 22 includes the sight point and the locking frame shown in fig. 4, the background image and the target are not included, and other information such as a firearm roll angle, residual capacity, firearm shooting direction and the like can be displayed or not;

the analyzer 21 is used for reflecting image light displayed by the display 22 and transmitting ambient light, the analyzer 21 is positioned above the left side of the display 22, the image light reflected by the analyzer 21 and the transmitted ambient light cannot be blocked by the display screen 22, an aiming point and a locking frame are arranged in an image reflected by the analyzer 21, the analyzer 21 transmits a real scene image, the reflected image light is parallel to the transmitted ambient light, the reflected image light and the transmitted ambient light enter eyes of a shooter, and the shooter can see the aiming point and the locking frame on the analyzer 21; after the transmission type AR mirror device is installed on the sighting device, the optical axis of the light analysis mirror 21 is parallel to the optical axis of the sighting device, so that the sighting device sends video to the transmission type AR mirror device and the ambient light is image information acquired for the same scene, and the sighting point and the locking frame in the reflected image of the light analysis mirror 21 are fused with the transmitted ambient light to achieve the purpose of auxiliary shooting.

The light analyzing mirror 21 is also called a half-mirror, and is formed by plating a layer of reflective film, also called a light analyzing film, and a transmissive film on a common lens, and changing the original ratio of projection and reflection by plating a film, and the film can increase the transmittance, increase the light intensity, increase the reflection, and decrease the light intensity, and the half-mirror means that the transmittance of the film is a certain ratio a, the reflectance is a certain ratio B, and a + B is 100%, that is, after light passes through the film, the transmitted light intensity is a ratio a of the original light intensity, and the reflected light intensity is a ratio B of the original light intensity, illustratively, a may be 50%, B is 50%, or a may be 60%, B is 40%, and specifically, a suitable reflective film may be selected according to actual conditions.

The light analysis mirror 21 adopted in this embodiment is a curved light analysis mirror 21, a concave surface of the curved light analysis mirror 21 faces the display 22, that is, faces the eyes of the shooter, a convex surface of the curved light analysis mirror 21 faces the shooting target, the display 22 is located on a focal plane of the curved light analysis mirror 21, and light rays emitted from the focal plane can be kept parallel after being reflected by the curved light analysis mirror 21, so that image light emitted by the display 22 is reflected by the light analysis mirror 21 to form parallel light to enter the eyes of the shooter, because natural light can be regarded as parallel light, ambient light reflected by a real scene is still parallel light after being transmitted by the curved light analysis mirror 21, and thus an aiming point and a locking frame in a reflected image of the curved light analysis mirror 21 can be fused with an image transmitted by the curved light analysis mirror 21.

Referring to fig. 7, in another design, the light analyzing mirror 21 is a plane light analyzing mirror 21, an acute angle is preset between the plane light analyzing mirror 21 and the optical axis of the collimator, the acute angle faces to the shooter side, since natural light can be regarded as parallel light, ambient light reflected by a real scene is still parallel light after being transmitted by the plane light analyzing mirror 21, image light output by the display 22 is parallel light, and the image light is parallel to the ambient light after being reflected by the plane light analyzing mirror 21, so that an aiming point and a locking frame in an image reflected by the plane light analyzing mirror 21 can be fused with the image transmitted by the plane light analyzing mirror 21.

The transmissive AR mirror device in this embodiment is provided with a video interface, the video interface is connected to the display 22, the video interface is further matched with the video interface on the collimator, and video information in the collimator is transmitted to the display 22 through the video interface and then displayed by the display 22.

The first display mode and the second display mode are switched by means of a controller 24 in the transmission type AR mirror device, video information sent by the sighting telescope to the transmission type AR mirror device firstly reaches the controller 24, and then whether the video information is sent to the display 22 is determined by the controller 24, in order to operate the controller 24, the transmission type AR mirror device is provided with a control interface, the control interface is matched with a control interface 18 of the sighting telescope, the control of the controller 24 is realized by operating a physical key 12 on the sighting telescope, and then the selection of the first display mode and the second display mode is realized.

Further, the transmissive AR mirror device is provided with the built-in power supply 23, and in case the battery assembly 17 is low or no power, the controller 24 controls the built-in power supply 23 to be powered on with the controller 24, so that power is no longer received through the power interface, and at this time, the controller 24 controls the display 22 to enter the second display mode, because in case the battery assembly is low or no power, the sighting device cannot provide video information for the transmissive AR mirror device, and only the split line or the red dot can be used for assisting shooting.

In another design mode, the display 22 has only one display mode, namely a first display mode, the built-in power supply 23 and the light source are added, under the condition that the battery assembly 17 is low in electric quantity or is not powered, the display 22 is turned off, the built-in power supply 23 supplies electric energy to the light source, light emitted by the light source is parallel to transmitted ambient light after being reflected by the light analyzing mirror 21, the same function as that of the red point sighting telescope is achieved, and the light source can be an LED lamp; if the light analysis mirror 21 is a plane light analysis mirror 21, the position of the light source should be adjusted to make the reflected light parallel to the ambient light transmitted by the plane light analysis mirror 21, and if the light analysis mirror 21 is a curved light analysis mirror 21, the light source should be located on the focal plane of the curved light analysis mirror 21.
