Influence of Statistical Characteristics of Speckle-Like Wave Fields on Their Optical Properties

A brief retrospective analysis of the study of speckles with Rayleigh and non-Rayleigh statistics is performed. Algorithms and computer models have been developed for generating light speckle fields with different probability densities of intensity values. The possibility of purposeful control of probability distributions and other statistical radiation parameters is demonstrated. The problem of the stability of the probabilistic and scaling characteristics of speckle-like monochromatic beams during their propagation in free space is considered. The possibility of formation of a delta-shaped intensity distribution in the histograms is established. Variants of using beams with different statistics in medicine and information optical systems are considered.
