摘要：

Scanning-angle reflectometry around the Brewster angle has been used to measure the reflectivity of a flat silica surface sparsely seeded with latex particles. The reflectivity for such surfaces is composed of 1) the direct (Fresnel) reflection from the silica-water interface, 2) the (Mie) scattering of the adsorbed particles and 3) the interference between the two previously mentioned components. The analysis of the obtained curves of reflectivity vs. incidence angle yields three parameters: particle size, refractive index of the particle, and the adsorbed particle density.
