SIMULTANEOUS OPTICAL-IMAGE PROCESSING BY PHOTON-ECHOES

The principles for designing optical information processing systems ba sed on the dynamic spatial and temporal properties of two-pulsed photo n echo signals are examined. The properties of the resonant medium use d as an operational filter of temporal and spatial frequencies, condit ioned by the sensitivity of exciting light pulses to the Fourier spect rum, are also discussed. It is shown that the ability of quantum reson ant schemes to degenerate, which manifests itself depending on the res onant response from the square amplitude of the second exciting light pulse, can be used for simultaneous correlative processing of optical images formed at the same moment in time. Differences between methods of simultaneous image processing obtained by means of Fourier optics a re discused.
