Abstract

Our paper concerns with statistical processing of digitally recorded straight equispaced fringe patterns by a numerical method based on discrete Fourier transforming (DFT) of the input data, which has the advantage of faster computation than the usual least square fitting method, that we have presented in a previous paper. This new method leads to the same accuracy as the least square fitting method and it is more convenient to use for processing fringe pattern with high harmonic order features.
