Abstract

Statistical characteristics of the far-zone partially developed dynamic speckles caused by diffraction of the focused Gaussian beam on the moving large-scale transparent scatterers are discussed. Scatterers under study are considered as the set of randomly distributed phase- distorting elements ('irregular lens-let array'). The technique of probability density function of effective focal length for local scatterers ensemble using the dependencies of speckle contrast or skewness coefficient on defocusing parameter is proposed. Some difficulties of analytical description caused by peculiarities of the phase distributions microtopology are mentioned. Applications of this approach to biotissue structure analysis are discussed.
