title: Refined fourier-transform method of analysis of full two-dimensional digitized interferograms.
abstract: A refined Fourier-transform method of analysis of interference patterns is presented. The refinements include a method of automatic background subtraction and a way of treating the problem of heterodyning. The method proves particularly useful for analysis of long sequences of interferograms.
