HOLOGRAPHIC COLLIMATOR SIGHT Russian patent published in 2020 - IPC F41G1/00 

FIELD: weapons.

SUBSTANCE: invention relates to holographic collimator sights which form a collimated image of an aiming mark using a holographic imager of a fixed mark image, and can be used in hand-held sports or live-action weapons. Holographic collimator sight comprises a source of monochromatic radiation, a relief-phase focusing reflecting holographic diffraction grating (FRHDG) and a holographic imager of the image of the fixed mark. Relief-phase FRHDG is made on a flat substrate, wherein between the monochromatic radiation source and the relief-phase FRHDG there is an axisymmetric expansion lens.

EFFECT: use of the invention enables to completely compensate for the angular aberrations of the collimated image of the hologram shape former of the fixed mark in the plane of the exit pupil, provide uniform illumination of the FRHDG, reduction of overall dimensions and weight of the sight, as well as simplifying the technology and reducing labor intensity of making holographic collimation sights.
