Abstract
The results of an experiment on compensation of random initial distortions of the wave front of an atmospheric backscattering signal from an additional laser source using the aperture sensing method are presented. The quality control of the correction was evaluated using a Shack-Hartmann sensor, as well as the intensity distribution at the end of the propagation path. It was shown that during the operation of the setup, the level of artificially introduced aberrations of the main beam decreased, the focusing quality increased, and the signal at the radiation receiver from an additional source increased.
