Paper Abstract

Algorithms of wavefront reconstruction and phase distortions compensation by an adaptive optical system of phase conjugation in the presence of measurement noises and errors of phase corrector control within statistics view on a base of variational and matrix methods are presented. Reconstruction and compensation of phase distributions use information about statistical characteristics of wavefront, measurement noises, and control errors. Equations for orthogonal Karhunen-Loeve type modes, providing minimum phase distortions compensation error, while the number of modes is fixed, and realized by phase corrector with fixed response functions without approximation error, are received and researched. Results of calculations of residual error of reconstruction and compensation of wavefront disturbed by atmosphere in an adaptive system with a different number of Gartman sensor channels and a different number of actuators via the value of measurement noises and control errors are presented.
