Reconstruction of the surface power spectrum from reflectivity data.
An analytical approach is used to determine the power spectrum of the surface roughness from experimental data for the reflectivity of randomly rough surfaces. A one-dimensional, randomly rough, perfectly conducting surface that is illuminated by s-polarized light whose plane of incidence is perpendicular to the generators of the surface is considered, and the power spectrum is obtained within the framework of phase perturbation theory. Good agreement with numerically generated experimental data is obtained.
