Abstract

Gaussian beam propagation through a thin screen and an extended random media has been studied using a beam propagation method. We use the modified von Karman spectrum model to describe the phase screen statistics. The scintillation index is analyzed as a function of the structure constant, phase screen location, the initial width and curvature of the Gaussian beam, etc. The numerical simulations are extended using a pair of Gaussian beams. We examine the interference of the beams and measure the fringe visibility at the target. The results are correlated with the scintillation index.
