Abstract
Adaptive optics can be used to improve the performance of a near-ground laser communication link by reducing intensity scintillation of an optical carrier collected by a down- range receiver. Such an adaptive optics system may include a Shack-Hartmann wavefront sensor to measure the wavefront of a beacon laser, and a deformable mirror to apply the appropriate conjugate wavefront to a transmitted communication beam. In this paper, we investigate the performance of such an adaptive optics system using multiple phase screen Monte Carlo computer simulations. Specifically, we consider the effects of intensity dynamic range of the wavefront sensor and of the aperture size of the adaptive optics on the mean and variance of the received intensity.
