Abstract

The numerical simulation of adaptive optical system operation with two sequentially located adaptive mirrors has been carried out. The control of the adaptive mirrors has been realized by the stochastic parallel gradient algorithm. The radiation power within the diffraction angle is the criterion functional of the algorithm. Two variants of system operation have been considered: in the first variant the mirrors have the joint control unit and the criterion functional sensor, and in the second one each mirror is situated in the independent contour. The similar adaptive systems can be applied to the correction of phase distortions of the radiation caused by turbulence of the atmosphere. It is shown that the efficiency of correction of phase aberrations by such adaptive system is high in the case of the independent contours at supplying relatively small stochastic voltages to the first adaptive mirror.
