METHOD OF RECORDING HOLOGRAMS Russian patent published in 1995 - IPC

Abstract SU 1823599 A1

FIELD: holography. SUBSTANCE: pulse laser radiation is passed through resonantly absorbing matter prior to illuminating object. Lifetime of metastable condition of the matter is equal or prevails time interval between pulses. Probabilities of forced transitions are less than probabilities of radiation-free transitions which cause darkness of the matter. Holograms are registered in specific time intervals. EFFECT: improved efficiency. 1 dwg
