Paper Abstract

In Fourier transform method for carrier fringe pattern processing, the variety of windows used is compared for their phase retrieving accuracy by computer simulations. The results show that, (1) Two dimensional Fourier transform method is better than the one dimensional transform; (2) The phase errors at image edges are large and should be discarded; (3) No new windows are needed since it is unlikely to improve the phase retrieving accuracy.
