Abstract

We consider the possibilities of information transmission in free space optical communication systems based on encoding with the help of the polarization structure of the synthesized laser beam. To control the polarization structure of beams, an approach based on the fiber array coherent combining with the possibility of changing the direction of subbeam polarization is used. On the basis of numerical simulation, the influence of atmospheric turbulent distortions, as well as the possibility of their adaptive compensation, is analyzed. Situations with different directions of subbeam polarization are considered. It is shown that, for the problems of information transmission, the most stable are the synthesized beams formed at the azimuthal or radial polarization of the subbeams.
