Abstract

The last 20 years have seen great developments in the prediction, measurement, and characterization of diffusing surfaces. Methods available for predicting and measuring the scattered polar distribution using boundary-element methods and maximum-length sequence stimuli are reviewed. The methods are used currently to characterize the quality and amount of diffusion produced by a surface are described, including diffusivity diffusion coefficients derived from predicted and measured polar distributions and scattering coefficients derived from direct measurements.
