Paper Abstract

Various interferometric and fringe projection techniques may result in complex interferograms with the information about the phenomena tested. Recent applications require the analysis on the base of a single interferogram. Here, we address two problems: simultaneous analysis of the information about two events and analysis of interferogram with high phase gradients in both x and y directions. The analysis of an interferogram is performed by the spatial-carrier phase-shifting method used sequentially for x and y sampling directions. The error analysis of the two procedures proposed is presented.
