Abstract :
The author summarizes the Wright Laboratory research conducted to determine the feasibility of using inherent information, such as angle-of-arrival fluctuations of incident radiation and spreading of the focussed spot size, obtained through the measurement of the diffraction limited aperture of the atmosphere (r0) to adaptively optimize laser communications system parameters. The method used to measure the r0 and details concerning the 8-km pulsed-laser communications link established are described
