Because of complex and multivalue properties of brightness function of isochromatic fringe, there exist enormous difficulties in automatic construction of fringe order distribution over the whole field of specimen in the framework of digital image processing using a microcomputer. In this study, the structure of the distribution function of fringe order is analyzed mathematically on a concept of unfolding, and a criterion for the reversal of rise of fall or fringe order is well established. Thus, on the basis of the criterion, the authors have successfully developed a general algorithm for the automatic calculation of fringe order over the whole field using a piece of isochromatic fringe pattern. Availability of the theory and algorithm are also shown in an example problem of three-point bending.
