Holographic aiming optical element and its producing method and use

Abstract

The invention is a hologram aiming optical element and its manufacturing method and application, which relates to a hologram optical element, especially manufacturing method and device for primary parts of the laser hologram aiming device. The hologram aiming optical element has a hologram dry plate, on the plate, there arranged with pattern information and infinite distance micro bright point information. It can record pattern information when in the first time of exposure on the hologram dry plate, and then records infinite distance bright point information in the second time of exposure on the same dry plate. The device includes device for recording the information of in the two times of exposures. The hologram aiming optical element is a hologram optical element, it can generate a near distance pattern and a remote tiny bright point under illuminating of laser diode, it can be applied to produce laser hologram aiming device.

Description

technical field [0001] The invention relates to a holographic optical element, in particular to a manufacturing method and a manufacturing device for a holographic aiming optical element, which is the main component of a laser holographic sight. Background technique [0002] There are many types of sights used on light weapons. The most common is the mechanical sight with the crosshair aligned with the notch. This sight has a solid structure and is cheap, but it can only be aimed with a single eye, and the aiming speed is slow and the accuracy is low. It is difficult for the human eye to aim when the target or the firearm itself is moving or when the ambient light is too low. Another common sight is the telescopic sight. Its main feature is its high aiming accuracy, but it is more suitable for aiming at long-distance stationary targets, and it is not suitable for aiming at short-distance fast-moving targets. There are also two optical sights: the red dot sight and the lase...

AI Technical Summary

Problems solved by technology

The aiming speed of this sight is slow, and because part of the light emitted from the LED directly hits the human eye, it makes people feel uncomfortable; in addition, because the human eye must observe through the half mirror, the brightness of the aiming target is greatly weakened, which is not conducive to effective aiming

The laser guide sight is to collimate the light emitted by a laser diode (LD) and shoot it directly to the aiming target. Its main disadvantages are: (1) The laser will be found by the enemy, which is not conducive to the concealment of the shooter; (2) If there are multiple shooters aiming at very close enemy personnel at the same time, it may be difficult to tell which laser point is emitted by their own gun; (3) When the distance is far and the background light is strong, it is difficult to see the Laser points scattered by objects
