Paper Abstract

A new approach is proposed for calculation of the intensity autocorrelation function in spectrum of white light scattering by a phase diffuser with an arbitrary distributed rough surface. Results of the calculations for gamma-distributed diffusers and integral polygaussian surfaces are presented. It is shown that in the absence of the coherent scattering the spectral correlation for non-gaussian diffusers isn't completely defined by the first-order height. distribution but depends also on the type of the surface autocorrelation and the statistical model of the roughness.
