Paper Abstract

In this paper we present a new method for the fringe pattern separation. Our method is useful when two fringe families are present in a single image, either in case when two of them carry an encoded information (e.g., three beam interference encountered in wedge or quasi-parallel plate testing), or when one pattern carries an information and the other one is parasitic and to be removed. The method is based on the two dimensional continuous wavelet transform and the modified Morlet wavelet. A new ridge extraction algorithm is proposed to deal with multiple fringe families. The validity and accuracy of the proposed method is confirmed by computer simulations.
