Embodiment Construction

[0023] Such as figure 1 As shown, in this embodiment case, there is provided: a laser emitting module 1 composed of a laser diode 6 and a beam expander system 7, a holographic lens 2 for collimating, filtering and deflecting the divergent light emitted by the laser emitting module 1 , the holographic lens 2 is located behind the laser emitting module 1 and is on the same optical axis as the laser emitting module 1; image 3 , the holographic image 3 It is placed on the upper front of the holographic lens 2, and placed parallel to or nearly parallel to the holographic lens 3 on the outgoing light path of the holographic lens 3.

[0024] Wherein the laser emitting module 1 is provided with a laser diode 6 and a beam expander 7. The laser diode can be a diode emitting green visible light waves or a diode emitting red visible light waves. The beam expander device is used to emit the laser diode The divergence angle of the beam is further expanded. The beam expander can be any b...

Abstract

The invention provides a holographic light path system comprising a laser transmitter module for supplying a light source to the system, a holographic lens for collimating, filtering and deflecting light emitted by the laser transmitter module, and a holograph with targeted and differentiated images; the holographic lens and the laser transmitter module are arranged on the same light axis; the holograph is arranged on the emerging light path of the holographic lens; and the laser transmitter module is internally provided with a laser diode and a beam expander for further expanding the divergence angle of a light beam emitted by the laser diode. The holographic light path system is simpler and compacter, has more flexible styles and is beneficial to solution to the problems of poor coaxiality of the light path system and greater structural length of the system in a traditional holographic collimator.

Description

technical field [0001] The invention relates to a holographic optical path system, in particular to a holographic optical path system applicable to a laser holographic aiming device. Background technique [0002] The holographic sight is a new type of sight that was applied at the end of the 20th century. It is the first application of holography in light weapons. Once it came out, it caused a huge response in the civilian and military fields with its unique performance. At present it has been applied to some troops in the United States and Germany. [0003] The holographic sight uses the diffraction differentiation virtual image of the holographic optical element for aiming, which has the advantages of fast aiming speed, good concealment and little environmental influence. Compared with other sights, it has a wider field of view, which can realize full sight aiming. It can be easily installed on any firearm, and the installation is fast and reliable, which does not affect...
