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.
我们提出了一种简单快速的正则化频率稳定方法，用于单幅开或闭条纹干涉图的解调。所提出的方法通过根据先验知识建立代价函数来恢复干涉图的相位图。由于代价函数仅使用要估计的相位场，因此优化过程很快。此外，恢复的相位是连续的，不需要进一步的相位展开。计算机模拟和实验结果证明了该方法的快速性和有效性。
