HOLOGRAPHIC SIGHT Russian patent published in 1995 - IPC

FIELD: optical equipment. SUBSTANCE: holographic sight has sighting mark produced in the form of hologram recording of image of sighting grid projected at infinity and light source with power supply source 4. Hologram 2 is reflective one, light source 3 is placed at angle not less than 10 deg to sighting axis. Hologram 2 in this case is manufactured synthesized from optically transparent layers with different refraction factors. EFFECT: reduced power consumption, diminished mass and dimensions, increased efficiency of use of light source. 2 cl, 1 dwg
