FIELD: laser equipment, specifically mass generation of film holograms under unstationary conditions. SUBSTANCE: coherent light flux is passed through photosensitive plate. Reflected from master hologram it forms interference field recorded on photosensitive plate. Placing laser at angle to photosensitive plate one can achieve high quality and brightness of holograms. EFFECT: increased generation efficiency and high quality of holograms. 2 dwg
