Abstract

It is interesting and useful to note that, even without carrier, the fringe pattern can still be processed for phase retrieving by Fourier transform method. A key problem is its phase retrieving accuracy, which is the topic of this paper. Our analysis shows that in some cases this method may introduce large phase errors and should be used with care.
