Paper Abstract

The intensity statistics of a laser light passing through a double phase screen are measured and compared with those predicted by the I-K distribution. The phase screens are produced in the laboratory by turbulent mixing of the convective hot air flow above a gas flame and the surrounding cocler air. Measurements are made over actual distances up to 60 feet behind the first phase screen with various separation distances between the two screens. The normalized intensity moments were found to be similar to those occuring in extended turbulence conditions, but here the normalized second moment never exceeded 3. In all cases we found the I-K distribution with parameter α = 3/2 to be an excellent theoretical model.
