Characterization Of Random Rough Surfaces From Measurements Of The Speckle Intensity

Abstract

A first communication "Electromagnetic study of speckle" has shown that the problem of the diffraction by a random rough surface in Optics can be solved rigorously using the laws of electromagnetism. In this communication, we show that these laws may be used to deduce some parameters of the rough surfaces from the speckle pattern, in some conditions, even though this problem appears at present time to be extremely difficult in the general case.
