PROCESS RECORDING ARRAY OF POINT IRIDESCENT HOLOGRAMS Russian patent published in 2002 - IPC

FIELD: optical holography. SUBSTANCE: optical axis of common lens is oriented orthogonally to initial direction of propagation of object and reference beams, these beams are deviated at angle of 90 deg with the aid of mirror and are directed to input of common lens. Optical head (common lens with mirror) and recording medium are moved independently, optical head being moved uninterruptedly, and laser radiation is modulated by short pulses which results in design of small-sized, low-inertia devices realizing given movements. EFFECT: increased speed of recording of array of point iridescent holograms. 1 cl, 2 dwg
