提出了一种混合模板匹配的光学条纹图位相解码技术，计算机模拟和实验结果分析证明：该技术不仅可以从含高频随机噪声（如散斑噪声）的条纹图中有效地复原位相分布，而且可以处理条纹图包含分割间断区域（如孔洞、裂纹、边界等）的位相复原问题。

A phase decoding technique is proposed to solve the problem of phase retrieval from an optical interferogram that is overlaid with random noise and segmented discontinuity. The technique is on the basis of a composite mask matching combined with a special phase unwrapping algorithm. The computer aided analysis and experimental interferograms show that the technique can be quite efficient in phase unwrapping procedure for interferograms in which speckle noise or true phase discontinuities or both may exist.
