Paper Abstract

The fringe-pattern normalization method by parameter estimation is used to relieve the critical filter's requirements 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.
