A two-scale approach to the diffuse light scattering from rough surfaces is proposed and applied for the first time. On the microscopic scale, the inter- and intra-layer contributions to the complex optical conductivity tensor are quantum mechanically calculated ab initio, based on the Luttinger formalism and by means of a contour integration within the spin-polarized relativistic screened Korringa–Kohn–Rostoker...
This paper discusses a promising method to investigate defects on high-gloss finished metal surfaces. The main aim is to detect very shallow scratches on such tribological surfaces. The method must be simple in its applicability, insensitive to external disturbances, and sufficiently fast for application in monitoring industrial processes. To achieve this, the principle of light scattering is used...
