Adaptive forming of beams and images through the atmosphere. Numerical simulation

The problem of compensation for atmospheric distortions of a wave front has been studied for a long time. The first papers on this subject were published in the mid-60s. At that time, however, the engineering base gave no way for designing the efficient devices for compensating for atmospheric distortions. In recent years much progress has been reached in developing wave front sensors and correctors and then fitting the optical facilities operating under atmospheric distortions with these devices. In this connection an increased interest of researchers is observed to the theoretical works concerning with selection of an optical design and configuration of the wave front corrections
