Abstract
Measurement of the local angle of arrival in a laser beam traveling in turbulence is achieved by frequency demodulating the heterodyne signal derived from the interference of a probe and a reference beam. The resulting data are then used to demonstrate that the statistical correlation between the angle of arrival and the irradiance is weak and that the random angle of arrival is normally distributed. These results constitute a direct confirmation of two fundamental assumptions of the theoretical model of propagation in turbulence previously developed at the Defence Research Establishment Valcartier (DREV).
