METHOD FOR OPTICAL-DATA PROCESSING BASED ON A 2-PULSE PHOTON-ECHO

The principles of optical data processing based on dynamic spatial tem poral properties of two-pulse photon echo signals are considered. The properties of a resonant medium as an on-line filter of temporal and s patial frequencies are discussed. These properties are due to the sens itivity of such a medium to the Fourier spectrum of the second excitin g pulse. Degeneracy of quantum resonant systems, demonstrated by the c oherent response dependence on the square of the amplitude of the seco nd pulse, can be used for <<simultaneous>> correlation processing of o ptical <<signals>>. Various methods for the processing of the Fourier optical images are discussed.
