Abstract
A system based on 2D Fourier transform method for accurate determinati on of the interference phase distribution from a sandwich interferogra m with carrier fringes is presented. The technique is particularly sui table for an evaluation of surface deformation in static as well as dy namic process. Some practical applications are shown.
