Phase correlation algorithm as a kind of image matching method has many advantages such as insensitive to noise, unrelated to illumination of target, immune to geometric distortion.

相位相关作为一种图像匹配技术对噪声有较高的容忍程度，检测结果与照度无关，受几何失真影响小。但该方法对旋转变化非常敏感。

Existing phase extraction algorithms are just insensitive to specifically error source, and can't satisfy high precision optical testing.

现有的相位提取算法只对某些特定的误差不敏感，不能满足高精度光学检测的要求。
