摘　　要：本文讨论一种测量位相同步变化的物体信息的莫尔偏折法——位移式莫尔偏折法。通过试件的旋转或摆动用条纹的移动来反映光束的倾斜,用条纹的稳定性来判断光轴的重合。该法简单、精度高且易于实现自动测量。文章论证了其原理,分析了测量精度并阐述了几种典型的应用。We suggest a Moire deflectometry for measuring the object with synchronous change of phase, displacement- Moire deflectometry. When the object is rotating or wiggling, the displacement of Moire fringe indicates the angle of axis, and the stability of fringe indicates coincidence of the beam axis. This method is simple and the automeasurment is easy with high accuracy. In this paper the theory, measuring accuracy and some applications of this method are introduced.
