Possibility of adaptive correction for atmospheric turbulent layer

Abstract

With the use of the methods of numeric simulation the possibility is analyzed of adaptive correction for randomly inhomogeneous layer of a turbulent atmosphere on the base of phase conjugation. The atmosphere was simulated as a set of random screens. The influence of different parts of distributed lens on distortions of a laser beam is considered as well as efficiency of corrections for screens placed on various distances from the transmitting aperture. It was shown that the most severe distortions were induced by turbulent layers located on the maximum distance from the plane of observation. At the same time correction for these layers is the most efficient.
