Holographic diffraction sighting telescope

Abstract

The invention provides a holographic diffraction sighting telescope. The holographic diffraction sighting telescope comprises a telescope body, wherein a laser used for emitting diffused light, a first reflecting mirror used for reflecting the diffused light for the first time, a second reflecting mirror used for reflecting the diffused light for the second time, an H diffraction grating filter plate used for filtering diffused light and deriving parallel light and an F holographic image window plate used for differentiating the parallel light into a holographic aiming image in the horizontal direction are arranged in the mirror body, and the diffused light emitted by the laser sequentially passes through the first reflecting mirror, the second reflecting mirror and the H diffraction grating filter plate and then reaches the F holographic image window plate to form the holographic aiming image for human eyes to observe. The definition of the holographic aiming image can be effectively improved, the problem of laser center wavelength drift is solved, the situations of focal length, aberration, parallax, large aiming split drawing image blurring noise, low brightness, generation of twin images and the like are reduced, and the aiming precision is improved.

Description

technical field [0001] The invention relates to the field of optical sights, in particular to a holographic diffraction sight. Background technique [0002] The holographic diffraction sight is a revolutionary quick-sight sight that directly observes the point of impact and uses the point of impact as an aiming mark. It has fast aiming, high-precision shooting, and can be used normally in extreme environments. It can be equipped with various guns, howitzers, rocket launchers, etc. on equipment. At present, the domestic holographic diffraction collimator cannot effectively overcome the drift of the laser center wavelength, which limits the further improvement of the laser collimation accuracy, which directly leads to focal length, aberration, parallax, aiming image blur, noise, low brightness, and twinning Phenomena such as imagery, so that there is a large error in aiming, and it cannot be used in actual combat.
