PROCESS OF HOLOGRAM RECORDING Russian patent published in 2001 - IPC

FIELD: optical holography, generation of iridescent holograms. SUBSTANCE: two-dimensional assemblage of beams is formed with the aid of high-speed deflector from one light beam of laser, these beams are split into object and reference waves which are individually reflected in symmetry with reference to two orthogonal planes, then they are optically integrated with provision of parallel direction of their optical axes, focused with the help of common objective lens into plane of recording medium, modulated by exposure, angle of orientation and/ or spatial frequency of holograms. Recording medium is consistently moved by time forming by that specified mosaic picture. EFFECT: enhanced speed of recording of iridescent subholograms, enlarged range of orientation and of spatial frequencies of interference bands which improves figurative qualities of such holograms and hinders their falsification. 8 dwg
