The main purpose of this paper is to improvement of isochromatics wrapped phase map can make the phase to unwrap successfully and get the physical quantity we want to know. There is a peculiar problem of isochromatic interaction in Phase-shifting techniques of photoelasticity.

中文摘要本论文主要的目的是利用负载相移法来求得相位图，并且使用相位展开的技术使相位图展开完成，得到我们所要求得的物理量-相对延迟量。

In addition, this article took the isoclinic information which unwrapped already into isochromatic formula to get the correct retardation. This method might not get the form of arc-tangent because there are not output quarter-wave plates in three and six phase-stepping methods. Therefore, this paper corrected it by load-stepping method.

另外，为了使相位展开技术能顺利完成，进而得到相对的延迟量，在修正等色线包裹相位图中的不连续点时，本文使用之方法是将修正完的正确等倾线数值带入等色线公式中，此法在三场与六场中因为少掉了输出的四分之一波板，造成公式的结果使得条纹角度分布非反正切形式，因此需另外使用负载相移法来做修正。
