Abstract

The problems to ensure an effective functioning of the controlled optical systems at the long paths in the turbulent atmosphere are presented. It is shown that the conventional techniques of adaptive optics do not allow us to suppress the optical field distortions under the conditions of the strong turbulence, when the intensity distribution acquire the pronounced speckle-structure and the wave front gains the topological defects (dislocations). Dynamical and statistical dislocation characteristics typical for the turbulent atmosphere are considered. Novel theoretical and experimental approaches to the dislocation problem are proposed and prospect of its practical solution are estimated.
