Dependence of Fractal Dimension of Biospeckles on Conditions of Illumination: Computer Simulation

Abstract

There were presented results of computer simulation of processes of scattering of laser light on biological objects with fractal structure. Dependence of fractal dimension of speckle pattern formed under illumination of model of biological object on fractal properties of object of interest and on correlation between diameter of laser beam and dimensions of biofractal was investigated.
