Abstract

To analyze fringe patterns, frequency and phase analysis of fringes becomes popular. It provides accurate results and automated processing. In this paper, the theories of the frequency and phase analysis methods using Fourier transform, Gabor transform, wavelet transform are introduced for shape analysis using gratin projection method, strain analysis using gratin method or iso chromatics and iso clinics analysis using photooelasticity. The applications of these methods are also described.
