Originální abstrakt

A lot of issues have to be taken into account when designing reliable free space optical communication link. Among these are e.g.,beam wander, fluctuation of optical intensity and loss of spatial coherence that are caused by atmospheric turbulence. This paper presents experimental measurements of the spatial coherence of the laser beam. The experimental setup is based on Youngs double pinhole experiment. Fringe patterns under atmospheric turbulence for four different pinhole separations are presented. From these fringe patterns the visibility is determined and the coherence radius is estimated.
