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

Embodiment Construction

[0020] Such as figure 1 , As shown in 2, the present invention adopts the method of secondary exposure to a holographic recording dry plate to make a holographic aiming optical element. The first exposure records the information of a crosshair pattern, and the second exposure records the information of a tiny bright spot at infinity. The optics for the second exposure differ only in the object light path. The first recording device such as figure 1 As shown, a laser 31, a beam splitter 32, reflectors 33 and 34, beam expanders 35 and 36, a dry plate for holographic recording 37, a frosted glass 38 and a transparent sheet 39 with a crosshair pattern are provided. The frosted glass 38 is closely attached to the transparent sheet 39 with the crosshair pattern, and the distance from the holographic recording dry plate 37 is preferably several centimeters. The reference light uses beam expansion light, and the distance between the beam expansion filter 36 and the holographic reco...

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...
