FIELD: optical processors. SUBSTANCE: method uses of multiple frequency-compressed input signal each of which has bundles of beams at matching frequency channels, and involves simultaneous generation of interference images for each channel and separation of power from images in order to produce frequency- compressed output. Separate functions which are done in each channel are produced by constructive and destructive interference in each channel image. EFFECT: simultaneous implementation of frequency-compressing circuit, amplification and control of power beam in single device. 10 cl, 3 dwg
