N2 - The fringe-pattern normalization method by parameter estimation is used to relieve the critical gfilter's require- ments in the Fourier transform method for phase demodulation. By the normalization procedure, the zero order spectrum is suppressed allowing a straightforward filtering in the Fourier transform method. Thus, the filtering procedure is carried out by the simple half-plane filter. The benefits of this Fourier normalized-fringe analysis scheme are tested by both computer simulation and optical experiments.
