Abstract

Some schemes of realization of amplitude-phase correction are considered. The problem of application adaptive corrections is solved at formation of laser beams in a turbulent atmosphere on the basis of use of a reference beam which propagate towards to the initial one, and in a plane of radiation of the reference beam there is the adaptive correction representing introduction of "predistortions" in the initial beam on is algorithms as "wave-front reversion", or "phase conjugation" fields of a reference beam. In a plane of radiation there is a rearrangement of an initial beam on the basis of measurements of fluctuations in a reference beam. In work on efficiency of correction of beam formation numerical research of influence of an errors of approximation of amplitude and a phase of a field is carried out a turbulent atmosphere in conditions of strong fluctuations of intensity.
