Abstract

The opposition effect manifested as a narrow peak in the angular distribution of the intensity of diffusely scattered light in the backward (antispecular or retroreflection) direction has been experimen-tally investigated. A monostatic bidirectional laser reflectometer was used to measure the opposition effect of gold surfaces under illumination of YAG and He-Ne lasers. The results are compared with a recent theory of the elastic scattering of light from a randomly rough metal surface that predicts such a peak in the retroreflectance direction which, under certain conditions, can be related to the localization of surface polaritons.
