FIELD: physics; optics.
SUBSTANCE: invention relates to adaptive space-time compensation for distortions of a coherent optical signal incurred by the transmission channel and can be used in fine focus assemblies for lasers, reversal or phase front compensation systems. The method of reversing the wave front of coherent optical radiation involves generation of maximum values of alternating components which determine maximum matching of phase fronts of received and reference fields of each sub-aperture on photosensitive areas of heterodyne receivers and comparing them with real alternating components. The comparison results are used to determine phase mismatch values of received and reference fields of each sub-aperture incurred during generation of an adaptive overall wave front.
EFFECT: shorter duration and increased accuracy of generating a phase-matched front of an inverse wave.
