Abstract

The formula of moiré fringe patterns produced from the near superposition of two fringe patterns with cosinusoidal profiles is presented. The method is applied to combinations of the fringe patterns involving cosinusoidal grating with consinusoidal grating/ cosinusoudat grating with Fresnel zone plate and equispaced concentric circles with equispaced concentric circles. The theory of interferogram transform based on the moiré fringe pattern technique is given and its application is discussed.
