DIAGNOSTICS OF 2-DIMENSIONAL FRACTAL STRUCTURES USING SCANNING COHERENT BEAMS

A method of studying two-dimensional random structures such as amplitu de screens with fractal properties using scanning focused and wide col limated beams is discussed. An analysis is made of the interrelation b etween the parameters of the structure functions of the intensity fluc tuations detected at a fixed observation point and the structural char acteristics of the particular screens. Results of experimental investi gations of model samples of random amplitude screens with fractal prop erties are presented. (C) 1997 American Institute of Physics. [S1063-7 842(97)01911-9].
