Abstract

I investigated the ability of two scattering theories to predict the scattering of light very near the specular beam. One scattering theory is based on a scalar approximation and the other takes into account the vector nature of light. The scalar theory is further developed using an approximation that the surface height variation is much less than the wavelength of light. Surface height profiles were determined using optical interferometric techniques. The angle dependent scattering was calculated and found to be in fair agreement with experimental values.
