Abstract

We present a simple and fast regularized frequency-stabilizing method for single open- or closed-fringe interferogram demodulation. The proposed method recovers the phase maps of interferograms by establishing a cost function, according to prior knowledge. Because only the phase field to be estimated is employed in the cost function, the optimization process is fast. Moreover, the recovered phase is continuous, and no further phase unwrapping is necessary. Computer simulation and experimental results have demonstrated both the rapidity and the efficiency of the method.
