Computer Simulation of Random Atmospherically Degraded Optical Beams

Abstract

This report develops a scheme for simulating randomly degraded optical beams including both phase and log-amplitude and the effect of their cross-correlation. The scheme works for optical degradations whose scale lengths range from much smaller to much larger than the input aperture size. An extension of the well-known Fourier transform method is used for the small scale fluctuations and a polynomial approach is used for the larger scale fluctuations.
