Abstract

The scattering of light from cylindrical surfaces is studied using Kirchhoff's scalar theory. The angular distribution of the mean scattered intensity is obtained as a function of the characteristic statistical parameters of the heights and this expression is used to characterize cylindrical rough surfaces by measuring the quotient T/σ; between the correlation length (T) and the roughness (σ) of the surface. It is shown that the scanning process inherent to usual detection systems can be replaced by single-step detection by using a screen and a CCD camera. This method can be applied to on-line wire surface testing where conventional procedures are inadequate.
