Abstract:

A comparison is made between theoretical predictions of the angular distribution of laser radiation scattered from a variety of rough surfaces and experimental measurements of fractal one. The surfaces were initially well characterized using a mechanical stylus instrument to determine the surface profiles. Scattering experiments were then carried out using both transmissive and reflective geometries and both visible and infra-red radiation. The results show that fractal models are appropriate in the infra-red region, whereas single scale models give better agreement with experimental results in the visible region. Great Britain.
