摘要

提出了一种校正普通投影仪用移相法测量任意物体时产生的相位畸变的方法。我们用投影仪测量了一些物体，它是市售的。在本文中，我们试图用所提出的方法来提高精度。该方法计算理想相位与观测相位的差值，然后将误差反馈到观测相位。采用该方法，测量精度可提高47%。

Correcting phase distortion of phase shifting method

We propose a method of correcting phase distortion which is caused when measuring any objects by phase shifting method with an ordinary projector. We have measured some objects with the projector which is commercially available [1]. In this paper, we try to improve the precision with the proposing method. The method calculates differences between the idealized phase and observed, and then feeding back the error to the observed phase. By using this method, the precision could be made better by 47%.
