PROCESS OF RECORDING AND RECONSTRUCTION OF OPTICAL HOLOGRAMS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 1994 - IPC

FIELD: technical physics. SUBSTANCE: in compliance with process of recording and reconstruction of hologram superimposed recording of two interference patterns is conducted in time sequence over complex-conjugate carrier frequencies of reference beam with various positioning of transparency along optical axis of objective of recording. After reconstruction of first recording complex-conjugate light beam is formed from light beam of zero order and is directed to output of second recording. Set of device to generate optical holograms is supplemented with second reference channel and set of device for reconstruction of holograms is inserted with unit for formation of complex-conjugate light beam. EFFECT: simplified design, improved authenticity of reconstruction of holograms. 5 cl, 6 dwg
