Paper Abstract

This work studies rough surfaces that undergo small random morphological changes. In the present paper, rough reflective surfaces are dealt with. Its roughness is larger than the wavelength of the He-Ne laser beam used to illuminate it. Speckle correlation of the scattered light is applied to study changes in the roughness. A theoretical model, which describes speckle correlation as a decreasing quadratic exponential function of roughness changes and was presented in a previous paper, is used. New experimental results from rough reflective surfaces in which the changes are simulated through immersion of the samples in liquids with different refraction indices are presented. Good agreement between the theoretical and experimental results is found.
