Abstract

The results of an experiment on adaptive correction of random initial distortions of the wavefront of a collimated laser beam based on the signal of atmospheric backscattering are presented. The backscattered signal was recorded by a receiver with a limited field of view from an additional source at a different wavelength. A coaxial transmitter receiving scheme with a large transmitting and small receiving apertures was used. The quality of the correction was assessed using the Shack-Hartmann sensor, as well as by the two-dimensional distribution of the intensity on the remote screen. It is shown that after adaptive operation, the divergence of the distorted beam decreases.
