Abstract

Some manifestations of the fractal-like behavior of speckle intensity fluctuations observed in quasi-elastic light scattering experiments with various optically inhomogeneous dynamic media are discussed. Following examples of scattering systems, which induce these fluctuations with fractal properties, are considered: moving random fractal amplitude and phase screens illuminated by broad collimated and sharply focused probe beams, single-scattering ensembles of Brownian particles, multiple scattered disordered media with stochastic or regular motions of scattering particles. Experimental results obtained with multiple scattering dynamic model media such as water suspensions of polystyrene spheres are presented.
