It shows that the maximum errorpercentage is 14.77%, the two results are very coincident by analysis. The error of result can basically satisfy the needs of the generic projects.
通过对比分析表明，两种分析方法的计算结果很接近，最大误差为14.77%，基本能满足一般的工程需要。

Intensity of Gaussian distribution impacts significantly the sensing signal of the defocus phase, in which the errorpercentage achieves 25%, but for other phase profile, the effect is ignorable.
光强高斯分布对散焦相差的曲率信号影响较大，信号百分比误差达到25%，对其他相差的曲率信号影响很小；
