According to the aiming range finder in the above embodiment, the range finder 20 at the front end of the housing 10 can measure the distance and give the distance data to the control main board 30, and the control main board 30 gives the distance information to the display device 50 for display. Since the mirror 40 is provided with a reflective film, image information displayed by the display device 50 can be seen by reflection. The aiming distance measuring device in the embodiment does not need to be provided with a contact lens 40 with higher cost, so that the cost is low. The aiming distance measuring device in the embodiment can realize the aim of the aiming mirror with the distance measuring function at lower cost.

The control motherboard 30 is typically a circuit board, and controls the ranging display device 50 to display images through a program recorded thereon.

The image information in this embodiment is typically a reticle including a centroid, distance data, and the like.

It should be noted that, the housing 10 is generally formed by a plurality of parts, and the plurality of parts are connected by a screw connection or a clamping connection, so as to finally implement the installation of the ranging device 20, the control motherboard 30, the lens 40 and the display device 50 in the housing 10.

In some embodiments, referring to fig. 3, the housing 10 is provided with a viewing channel 100 and a light reflecting channel 200, and the lens 40 is disposed at the intersection of the viewing channel 100 and the light reflecting channel 200.

The sight is generally classified into an electronic display and an eyepiece display, and the electronic display generally displays a target on a display similar to an eyepiece by capturing an image through a camera on the sight instead of directly observing the target by naked eyes. Typically, such sighting telescope is provided with night vision. Eyepiece displays are direct observations of the target by the human eye.

In this embodiment, an eyepiece is used, and the lens 40 acts as an eyepiece. The housing 10 is provided with a field of view channel 100 to facilitate the observation of a firing target by a shooter. Accordingly, the light reflecting channel 200 is an optical path of the display device 50 so that the lens 40 can reflect the image displayed by the display device 50 without any obstruction.

It should be noted that, the light reflecting channel 200 is preferably disposed opposite to the direction of the observer, so as to avoid the light displayed by the light reflecting channel 200 from injuring the eyes of the person.

The purpose of the lens 40 at the intersection of the viewing channel 100 and the retroreflective channel 200 is to allow the shooter to view both the shooting target and the reticle and distance data displayed by the display device 50.

The main body of the lens 40 is made of transparent glass, PC plastic, etc. The reflective film may be attached to the lens 40, and the reflective film may be made of various materials, so long as it can satisfy the functions of reflecting light and transmitting light.

Specifically, the reflective film is a polarizing film, and the polarizing film only allows polarized light waves in one direction to pass through, so that light emitted by the display device 50 can be reflected and imaged on the polarizing film by presetting the light emission spectrum and the light emission direction of the display device 50.

Alternatively, a filter is used for the reflective film. The filter is a self-colored transparent substance having optical means for reflecting certain wavelengths and absorbing certain wavelengths of the viewing beam. By presetting the color of the light emission of the display device 50, it is made possible to be reflected by the filter to be imaged. Typically, the display device 50 emits light in both red and green colors. Accordingly, the reflective film also has a function of reflecting the display device 50.

More specifically, the parameters of the reflective film are: red light with the wavelength of 400-600 nanometers has the transmissivity of more than 90 percent, red light with the wavelength of more than 640 nanometers has the reflectivity of more than 90 percent; the wavelength is 400-700 nm, and the transmittance is more than 50%. The light emitted by the display device 50 may be red-green light having a wavelength between 400-700 nanometers. Thus, the light emitted by the display device can be reflected while the visual field of the shooter is not blocked.

In combination, the mirror 40 corresponds to a mirror that specifically reflects the image of the display device 50.

In certain embodiments, the lens 40 is arcuate.

The arcuate lens 40 serves two primary functions; in one aspect, the arcuate lens 40 may provide a wider field of view for shooting. On the other hand, the curved lens 40 may focus the image displayed by the display device 50, with the center of gravity in the final displayed image being at the center of the lens 40.

Typically, the arcuate lens 40 is concave on the side facing the shooter and convex on the side facing away from the shooter.

In some specific embodiments, the display device 50 is located at the focal length of the lens 40.

The display device 50 is positioned at the focal length of the lens 40 to provide more clear imaging.

In certain embodiments, the display device 50 further comprises an adjustment mechanism 510 and a display screen 520, the adjustment mechanism 510 being coupled to the housing 10, the adjustment mechanism 510 being configured to change the position of the display screen 520 displayed on the lens 40.

In this embodiment, the rotating shaft 5101 is rotatably disposed on the housing 10, and the rotating disc 5102 is fixedly connected with the rotating shaft 5101. By toggling the rotary plate 5102, the rotary shaft 5101 is rotated to change the light path reflected by the display screen 520, and finally, the purpose of adjusting the imaging position of the display screen 520 on the lens 40 is achieved.

It should be noted that the purpose of changing the display position of the display device 50 on the lens 40 may also be achieved by other means. For example, adjustment of the display device 50 may be accomplished by way of an adjustment knob. Specifically, the adjusting knob is connected with the casing 10 by a bolt and is fixedly connected with the display device 50. The purpose of adjusting the imaging position of the display device 50 on the lens 40 is finally achieved by rotating the adjusting knob to lift the display device 50.

For another example, the display device 50 may be slidably coupled to the housing 10, and the position of the display device 50 may be changed by sliding to thereby achieve the purpose of adjusting the imaging position of the display device 50 on the lens 40.
