Abstract

The Fourier Transform Method (FTM) of fringe pattern analysis is one of the most important phase measuring techniques. Its chief advantage is that it requires only one interferogram which is crucial for industrial inspection. The goal of a fully automated phase retrieving technique, however, remains still elusive. Several refinements in 2-D FTM are proposed to achieve fully automatic, high-accuracy analysis of a fringe pattern. The new possibilities of on-line analysis ensuing from the recent advances in microcomputer technology are discussed.
