Description

Technical Field

[0001] The present invention relates to the field of aiming devices, and particularly to a digital integrated holographic sight. Background Art

[0002] Due to visual distortion at the edges, traditional red dot reflex sights cannot achieve a short focal length and a large field of view. At the same time, the overall parallax is relatively large, which has a great impact on aiming accuracy and cannot meet the requirements of precise shooting. Also, the overall size is relatively large, the related production costs and assembly pressure are high, and the overall durability is low. While holographic sights use the diffraction principle of lasers to reproduce the aiming ring, so there is no parallax at the edges. At the same time, the structure of the holographic sight is relatively fixed, and the optical components are all encapsulated inside the cavity, so the reliability is high. However, the existing aiming devices have relatively single functions and cannot display other relevant shooting information content on the sight, so the overall use effect is poor and cannot meet the existing use requirements. Summary of the Invention

[0003] The purpose of the present invention is to provide a digital integrated holographic sight, which solves the technical problem of single function and inability to display other content in the prior art, and realizes the technical effect of enriching the functionality of the device and facilitating the display of other information.

[0005] A digital integrated holographic sight, comprising a mounting cylinder and a mounting box. The mounting cylinder is a cuboid as a whole, with a cavity inside and openings at both ends. Inside the mounting cylinder, a collimating mirror and a holographic plate are respectively arranged near the openings. A display screen mounting box is fixed at the upper end of the mounting cylinder. There is a slot at the connection between the display screen mounting box and the mounting cylinder. A display screen is fixed inside the display screen mounting box. The display screen is arranged directly opposite the collimating mirror. A picture processing module is fixed on the side of the display screen away from the collimating mirror for projecting images. The mounting box is located below the mounting cylinder, and its upper end is fixedly connected to the mounting cylinder through a mounting bracket. Inside the mounting box, there is a diffraction grating. The diffraction grating is located below the holographic plate and is offset towards the side close to the collimating mirror. A mirror A is arranged on the side of the diffraction grating close to the collimating mirror. The side of the mirror A facing the holographic plate is inclined at 15°. A mirror B is arranged below the diffraction grating. The mirror B is inclined at 15° and faces the mirror A directly. A light emitting device is arranged on the side of the mirror B away from the holographic plate. The light emitting device is arranged directly opposite the mirror B.
