Embodiment Construction

[0016] The following embodiments will further illustrate the present invention in conjunction with the accompanying drawings.

[0017] see figure 1 , the embodiment of the present invention is provided with: a laser diode (LD) 1, a concave lens 2, a transmission holographic matching element 3 and a transmission hologram 4.

[0018] Laser diode 1 is used to emit red visible light waves to provide light source for the system. The laser beam emitted by the laser diode 1 is divergent light, and the central light of the divergent light is in the horizontal direction.

[0019] The concave lens 2 is used to further expand the divergence angle of the divergent light emitted by the laser diode 1, so that the laser beam can reach the required beam area in a short running distance. The concave lens 2 is placed vertically in front of the laser diode 1, and the center point of the concave lens 2 It is on the same horizontal line as the central ray of the beam emitted by the laser diode 1...

Abstract

The invention provides a compact matching type holographic aiming device optical system, which relates to a holographic optical system. The compact matching type holographic aiming device optical system has compact structure, and can realize accurate aiming in any condition. The compact matching type holographic aiming device optical system is provided with a laser diode, a concave lens, a transmission-type holographic matching element and a transmission-type hologram, wherein the concave lens is perpendicularly arranged in front of the laser diode; the transmission-type holographic matching element is perpendicularly arranged in rear of the concave lens; the laser diode, the concave lens and the transmission-type holographic matching element are arranged on the same optical axis; and the transmission-type hologram is arranged on the upper rear of the transmission-type holographic matching element.

Description

technical field [0001] The present invention relates to a holographic optical system, in particular to a compact matching holographic collimator optical system for a holographic collimator device. 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 t...
