摘要：

An algorithm for automatic tracing of fringes from a digitized interferogram is proposed. The main feature of this method is that fringe centers are traced by a predictor-corrector scheme, where knowledge of the approximate fringe normal and tangent at the current point on a fringe is used to guess at a trial location for the next point. A search along the fringe normal at the new trial location then yields the exact next point on the fringe.
