Abstract:

This paper reports a study of the speckle images of a scattered laser beam in the focal plane of a receiver objective, experimentally recorded by a photodetector array, as a function of the laser-pulse energy, the illumination angle of the objective, and the spectral composition of the radiation. Regularities are revealed that connect the statistical parameters of the images under various irradiation conditions. It is shown that the speckles obey Gaussian statistics only at small angles of illumination of the receiver objective.
