Abstract

We study into the ways of eliminating the interferogram fringe discontinuities and obtaining the connected interference fringes, which is needed for wave reconstruction. For this purpose, the decision function was calculated for pairs of fringe discontinuity points with regard to a variety of fringe geometric characteristics. The studies are conducted using computer-simulated interferograms. The developed algorithms are shown to be suitable for eliminating fringe discontinuities and obtaining connected interferogram fringes.
