A robust free space optical communication system

Abstract

Free space optical communication system sends information from one place to another optically through free space.One major issue of free space optical communication system remains tackling the effect of atmospheric turbulence in air through which the beam propagates. In this article we provide a brief overview of a recent development in which it is shown that using the property of orthogonal aberration modes,called Zernike modes, it is possible to send information from one place to another in a robust manner even in the presence of atmospheric turbulence.
