Paper Abstract

Interferograms with closed loop fringe patterns pose numerous difficulties while labeling. Most automatic fringe numbering routines fail while encountered with fringes of complicated shapes. An interactive fringe numbering routine which uses a gray scale coding technique in the form of pseudo coloring to help the machine to identify each order during data input is presented. Each fringe is traced individually and coded with different colors (gray levels) according to its order. The computer is informed of the order of each fringe and the corresponding gray level, so that while it scans the peak contours for data input, it identifies each order even if the fringes are concentric.
