Fluctuations of the parameters of probe radiation traveling in a bleached zone created in an aerosol medium by radiation of different wavelength

The geometric-optics approximation is used in the derivation of expressions for the square of fluctuations of the intensity level and for the structure function of fluctuations of the phase of a beam of probe radiation traveling in a bleached disperse medium. Fluctuations of the parameters of the medium appear as a result of mixing of inhomogeneous temperature and water-content fields by a random-velocity wind. A comparison is made of the calculated fluctuations of the intensity with those measured in an artificial fog chamber.
