Embodiment 1

[0024] Embodiment 1: When the beam expander is a convex spherical mirror and the hologram is a transmission hologram, the structure of the optical path system of the sight is as follows figure 1 As shown, the holographic lens 3 is arranged obliquely below the beam expander 2 and placed on one side of the outgoing light of the laser diode 1, and the hologram 4 with an aiming and dividing image is arranged above the holographic lens 3 and placed on the laser diode 1 side. The other side of diode 1's outgoing light.

Embodiment 2

[0025] Embodiment 2: When the holographic lens is a reflective holographic lens, and the hologram 4 with the aiming reticle image is a transmission hologram, the structure of the optical path system of the sight is as follows figure 2 As shown, the holographic lens 3 is placed parallel to the hologram 4 with an aiming reticle image, and is placed on both sides of the outgoing light of the laser diode 1; the holographic lens 3 is placed near the laser diode 1, with an aiming reticle A hologram 4 of the image is placed on the near side of the beam expander 2 . Wherein the laser diode 1 can be a diode that emits green visible light waves or a diode that emits red visible light waves, and the beam expander 2 is used to further expand the divergence angle of the beam emitted by the laser diode 1, so that the area of ​​the divergent beam is within a short distance The holographic lens 3 can be illuminated, and at the same time, the reflective beam expander 2 (convex spherical mirro...

Embodiment 3

[0027] Embodiment 3: When the holographic lens is a reflective holographic lens, and the hologram with the aiming reticle image is a reflective hologram, the structure of the optical path system of the sight is as follows figure 2 As shown: the holographic lens 3 and the hologram 4 are placed on both sides of the outgoing light of the laser diode 1; the holographic lens 3 is placed near the laser diode 1, and the hologram 4 is placed near the beam expander 2 and is approximately parallel to the The beam expander 2 is placed (meaning that the reflective surfaces of the two devices are parallel). It can be further seen from the figure that the hologram 4 is placed obliquely above the parallel light output from the holographic lens 3, and the parallel light output from the holographic lens 3 is incident on the hologram 4, and the hologram 4 and the holographic lens 3 are aligned in a certain manner. The included angle is placed and matched, so as to compensate for the change of ...

Abstract

The invention provides a collimator light path system for collimating a light beam by using a holographic lens. The collimator light path system comprises a laser diode for providing a light source, a beam expansion device for expanding the light beam emitted by the laser diode, the holographic lens for collimating, filtering and deflecting the expanded light beam, and a hologram positioned on an emergent light path of the holographic lens, wherein the hologram has collimation graduation images. The holographic light path system is simple and compact and has a flexible style; and the problems of complicated light path, single style and the long system structure in the conventional holographic collimator are solved.

Description

technical field [0001] The invention relates to a holographic optical path system, in particular to a holographic optical path system suitable for a laser holographic aiming device, that is, an optical path system of a sighting device which uses a holographic lens to collimate a light beam. Background technique [0002] The holographic sight is a new type of light weapon sight. One of its advantages is that it is extremely convenient to aim, allowing the shooter to notice the aiming mark and the target at the same time in an instant, that is, to keep a clear line of sight at all times. The shooter can grab the target with a wide field of view and press the aiming mark on the target in a split second, and conveniently continue to press the aiming mark on the target when the weapon recoils or the target is moving quickly. In short, when shooting, the shooter only needs to hold the weapon with his shoulders, open his eyes, and focus his sight on the target. The aiming mark of t...
