Abstract

Manifestations of the fractal properties of scattering objects such as rough surfaces in the speckle intensity fluctuations have been studied experimentally and by using computer simulation. The relationships between correlation properties of the boundary field phase distributions and far-zone intensity fluctuations have been studied for different illumination and observation conditions. Also the dependencies of second- and higher-order statistical moments of these fluctuations on the detection conditions have been investigated for fractal and subfractal scatterers. Some applications of the developed technique for surfaces quantification and testing are discussed.
