Abstract

An automatic fringe analysis method for interferograms with an arbitrary closed loop fringe pattern is developed, using an automatic fringe extracting and coding technique in the parallel pseudo-contour tracing form. The principle and procedures have been discussed in detail. It is shown that this method is very easy and convenient in practice.
