According to this method,four different 11-step algorithms with four different window functions which are rectangular window,triangle window,hanning window,and blackman window are designed. Analysis and simulation show that hanning window and blackman window with small lobes are less sensitive to errors. Seven different algorithms with the same phase shifting interval π/2 are designed by hanning window function,whose phase shifting steps are separately 5,11,15,39,51,76 and 101 steps.

选择矩形窗、三角窗、hanning窗和blackman窗生成4种11步移相算法，对振动误差和相移误差的分析验证了旁瓣小的hanning窗和blackman窗生成的算法对误差的灵敏度要小；再选择hanning窗生成了移相间距为π/2的5，11，15，39，51，76和101步7种移相算法，仿真验证了步数越多主瓣越小，对振动抑制能力越好，但需要更高的微位移器移动精度来获得有效的干涉条纹。

The algorithm utilizes the rotating transformation theory of vector, and derives a mathematical expression of trigonometric function which has the interval monotonicity.
