phase angle error

The error of phase-shifting always exists in experiments and it will cause the error in phase reconstruction.

重构光场的相位是光学干涉计量的基础和难点,相移技术是其中重要的方法,但相移误差在实验中是很难回避的,从而引起相位重构出现误差,所以如何消除或减少相移误差对相位重构的影响是受普遍关注的问题。

After studying the error of reconstructed phase caused by the error of phase-shifting,we have got the relation between the error of reconstructed phase and phase-shifting,and present a compensation algorithm that bases on digital holography four-step phase shifting and interference fringe fit with cosine function.

分析了在常用的四步相移中相移误差对相位重构造成的误差,给出了相移误差与相位重构误差的关系式,提出了通过干涉条纹的拟合来计算相移误差的方法,并将该方法应用于数字显微全息术测量细胞相位的实验中,得到了比较理想的细胞三维形貌。
