Abstract

The intensity statistics for a laser beam propagating through a random phase screen was compared to the H-K distribution. Since the H-K distribution was derived from the conditionalization of the Rician distribution with the Gamma distribution, experimental intensity data was collected to verify these distributions. The intensity data was first lowpass filtered to yield statistical moments that were found to be in agreement with those of the gamma distribution. Next, the intensity data was segmented into small time ,intervals, in which all time segments with approximately the same variance were grouped together. The statistical moments for these new time series were then compared against the moments for the Rician distribution. The moments for the segmented time series matched the moments for the Rician distribution extremely well.
