Paper Abstract

We report on the analysis of experimental data collected at the United States Naval Academy in the Summer and Fall of 2010. A low-power red He-Ne laser source was used to generate a Gaussian beam. The beam was directed horizontally above the ground and over the water for 400 m during daytime. The transverse cross-section of the beam was projected on a white screen and imaged using a ccd camera. The histogram of the fluctuating intensity at the center of the beam was obtained from the sequence of photographs. Comparison was made of the histogram and probability density functions of fluctuating intensity based on two existing analytic models, Gamma-Gamma and Gamma-Laguerre. Also the comparison of the beam statistics above the ground and over the water was performed.
