In this paper, we used path-following method tounwrap actual objects measured by project, and got the conclusion that thephase derivative variance is generally the most reliable measure of phasequality, while the maximum phase gradient correctly marked thediscontinuity domain.
利用质量图导引算法对实际物体进行了相位展开,实验结果表明:相位导数偏差质量图能够比较好的反应截断相位质量,而最大相位梯度质量图可以正确标识出不连续区域。 因此应该根据实际情况选择合适的质量图作为展开路径的质量导引。
