The photon echo application for optical digital processing of discrete images by the method of managing operators was examined. Photon echo is the pulse of light which is emitted spontaneously from a system of atoms previously irradiated by two or more coherent light pulses with length and power of 102divided by10-1 ps and 104divided by105 kW, respectively. These systems of resonant atoms are crystals with various paramagnetic activators. By using photon echo, the resonant systems are able to store and retrieve wave-front and temporal form of one of the excitation pulses. The photon echo application for information processing allows one to solve a number of problems with high efficiency. Different photon echo generating conditions can be utilized practically in all processor components, which creates certain prospects for using this effect in optical computing purposes.
