Original Abstract

Correlation of laser speckle fields generated by light of two different wavelengths, which illuminates succesively a randomly rough surface, is solved theoretically within the framework of the scalar Kirchhoff theory of wave scattering from random rough surfaces. The Fresnel approximation is used in description of scattered wave. The solution is used for surface roughness measurement by means of the digital processing of corresponding specklegrams.
