Paper Abstract

Several random bi-dimensional rough surfaces with known Gaussian statistics were made in the laboratory. The surfaces were coated with a thin film of aluminium to increase the surface reflectivity. Light coming from a source is incident to the surface at an angle theta and the light is reflected from the surface according to the distribution of slopes. Glitter patterns were measured with a CCD to differents reflection angles. Statistical properties were obtained and analyzed. At the same time, glitter patterns of sea surface were analyzed in order to obtain statistical properties of the surface heights. The results show that it is possible to obtain statistical properties of the surface heights from their glitter patterns.
