An inconsistency is one of the engineering obstacles to unwrap phase.

相位解缠面临的困难之一是相位的不一致性。

Computer simulation and experimental results make it clear that this method can effectively remove noise in phase map, unwrap the wrapped phase, and reconstruct the surface of the detected object.

计算机模拟和实验结果均证明，此方法能有效地去除相位图中的噪声，实现带噪声的主值相位图的相位展开，可靠地重建被测物体的表面形貌。

The main purpose of this article is to improvement of isochromatics wrapped phase map can make the phase to unwrap successfully and get the physical quantity we want to know, relative retardation.

本文的主要目的是修正光弹等色线包裹相位图，使相位展开技术能顺完成，进而得到我们须要得知的物理量-相对延迟。
