Abstract: After recalling rough surfaces modelling and theoretical study of light scattering from such surfaces, we present in this paper an experimental set-up to measure backscattered light with a very high angular selectivity. The device is then tested for various samples such as white diffusers, ground metallic surfaces and eventually silver mirrors. When the surface is diffusive, very accurate results can be easily obtained. For surfaces with a specular peak, stray scattering from the surrounding can make the measurement very difficult. However, even in that extreme case, we have been able to investigate into the inverse problem thanks to the angular selectivity and have found quite a reasonable value for the correlation length.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering.
