Paper Abstract

The process of moire interferometry is given mathematical description in terms of the classical theory of optical interference. The governing relationship between displacement and fringe order is derived, and the analysis is extended to cover carrier patterns, double exposure methods, and initial fringe pattern elimination. Various processes for obtaining patterns of displacement derivatives are also described mathematically.
