Abstract

A novel phase unwrapping algorithm for photoelasticity, based on the modulation ordering, is proposed and experimentally verified. The path for phase unwrapping is determined by the intensity modulation in the pixels, on the boundary of the phase unwrapped areas. Therefore, the algorithm is very robust, and in the worst case the error, if any, is limited to local minimum areas.
