In order to overcome the disadvantages of Fourier transform analyzing nonstationary signals, the invariable resolution of Fourier transform, and the uncertainty scale of dilating Fourier transform, the Gabor wavelet transform is applied to analyze the spatial carrier-fringes. By introducing the Gabor wavelet to analyzing the spatial carrier-fringe patterns, the modulated phase distribution relative to the fundamental frequency is obtained finally. The theory, accuracy check using a simulation and an example of 3-D shape measurement are shown.
