PROCESS OF GENERATION OF COLOR HOLOGRAPHIC IMAGE Russian patent published in 1997 - IPC

FIELD: laser equipment, in particular methods and devices to generate color holograms in counter propagating beams under unstationary conditions. SUBSTANCE: coherent luminous flux is formed in red, green and blue parts of spectrum, it is directed through coat with photosensitive layer on to holographed object, interference field is formed by reflected object wave which is recorded on mentioned coat. Coherent luminous flux is directed in turn by red, green and blue parts of spectrum through above-said coat. Sources of coherent luminous flux are positioned relative to coat with photosensitive layer at angle which values lie in range +/- 10 deg from Brewster angle. EFFECT: increased efficiency of process. 1 dwg
