Abstract:
A modified form of a phase tracking method to demodulate a single fringe pattern is presented. Phase values from local areas of the interferogram are recovered by means of a spatial synchronous technique instead of solving the set of nonlinear equations obtained from the implementation of the ordinary algorithm. This results in a significant speed improvement of the method. Additionally, the robustness against noise is maintained, and the sensitivity to contrast variations is decremented with respect to the phase tracking technique.
