Abstract: 

Far-zone speckles formation due to coherent beam diffraction on fractal structures is discussed using the random phase screen approach. Relationship between parameters of the structure functions of boundary field phase and speckle intensity fluctuations has been analyzed. Biotissues structure imaging technique using local estimations of the intensity exponential factor has been developed. Experiments with psoriasis human epidermis using scanning speckle-correlometer have shown the adequacy of the obtained 2Dimages to structure evolution character caused by disease progress.
