Abstract

This paper is a study of the principles of a new method of rough-surface interferometry (ROSI). We review some properties of the higher-order probability density function (pdf) of correlated speckle fields and discuss some assumptions that are usually made silently. This pdf is used to investigate statistical properties of intensities and phases in a dichromatic speckle field; the results are applied to ROSI. The experiments described confirm the theoretical results.
