Novel holographic electronic aiming device

Abstract

The invention belongs to the technical field of electronic collimators, and specifically relates to a novel holographic electronic collimator, which includes a holographic lens, an image sensor, a processor and a holographic display screen, and the holographic lens, image sensor, processor and holographic display screen are sequentially connected, The holographic lens is fixed on the gun, and a holographic image capture unit that can move arbitrarily in the horizontal direction is arranged in the holographic lens, and the holographic image capture unit is connected with an image sensor; the new holographic electronic sight provided by the invention can only It is only necessary to set the holographic lens on the gun. When the holographic image is acquired by setting the holographic image capture device inside the lens, the magnification of the lens can be adjusted, the viewing angle changes, and the image collected by the holographic image changes accordingly. At the same time, the magnification and viewing angle can be adjusted, and the display device is further separated without being integrated on the electronic sight, which improves the stability of long-term use.

Description

technical field [0001] The invention belongs to the technical field of electronic sights, and in particular relates to a novel holographic electronic sight. Background technique [0002] The holographic sight uses the reproduced holographic virtual image to aim, which has the advantages of fast aiming, high aiming accuracy, and is not affected by climate and environmental conditions. Holographic sights can be installed on various firearms. Because they have advantages over other types of sights in close-range gun battles, holographic sights have been highly valued by military departments of various countries in recent years. [0003] A holographic sight must contain a laser diode (LD) and a hologram. The laser emitted by the LD is irradiated on the hologram, and the human eye can see a holographic division image presented in the distance through the hologram, and use this image to aim at the target to be shot. In the development of the holographic sight, there are two poin...

Problems solved by technology

[0004] In the prior art, although it has been proposed that the holographic sight can be made small and light, it still cannot meet the second requirement above. The reasons are: (1) During the use of the sight, the temperature of the LD increases and the output wavelength (2) The coherence of the laser emitted by the LD is poor, which makes the aberration of the hologram very large, so the holographic image is not clear
