Abstract
This paper presents a method of measuring the roughness of a reflecting surface by studying the contrast ratio of a holographic interference pattern of this surface. A practical experimental configuration is illus-trated along with the measurement results obtained for a set of lapped steel specimens. In addition, an approximate scalar theory is presented that correlates well with experiment.
