Reconstruction of the surface-height autocorrelation function of a randomly rough dielectric surface from incoherent light scattering

摘要

An analytic approach is developed for obtaining the normalized surface height autocorrelation function of a one-dimensional randomly rough dielectric surface from experimental scattering data. It is based on the contribution to the mean differential reflection coefficient, obtained in the Kirchhoff approximation, from the light scattered incoherently. The incident light is s polarized, and its plane of incidence is perpendicular to the generators of the surface. Good agreement with numerically generated experimental data is obtained.
