提出了一种精确的位相展开算法，用于重构变形干涉图的真实相位场。该算法是可靠性排序和残差掩码的结合，同时引入了更可靠的展开基准信息。在对金字塔相位图、复杂的模拟干涉图和真实变形干涉图进行的测试中，该算法成功地以完美的精度展开了图像。该算法在精度上也优于目前流行的改进的Goldstein的残割算法。
An accurate phase unwrapping algorithm is presented for reconstructing the true phase field for deformation interferograms. This algorithm is a combination of reliability sorting and residue mask, while introducing more reliable unwrapping fiducial information. In tests conducted with a pyramidal phase image, a complex simulated interferogram, and a real deformation interferogram, the proposed algorithm successfully unwraps the images with perfect precision. This algorithm is also shown to be superior to the prevailing improved Goldstein's residue-cut algorithm in terms of precision.
