To measure shape, deformation, stress, strain, movement and vibration of structures, phase analysis methods of grating and fringe patterns are proposed by many researchers. Phase analysis provides accurate results. In this paper, some phase analysis methods developed by the authors are shown. There are two groups of the methods. One is the group of accurate methods such as the Fourier transform method, the Gabor transform method, the wavelet transform method and the phase-shifting method using Fourier transform. The other is the group of high-speed methods such as the method of extraction of characteristics, the scanning moire method, the phase-shifting scanning moire method, the phase-difference scanning moire method, the phase-shifting method using correlation with rectangular function and the integrated phase-shifting method. The principles of these methods and applications to measure shape, strain and stress analysis are shown.
