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。
We suggest a Moire deflectometry for measuring the object with synchronous change of phase, displacement- Moire deflectometry.
该法信号读出方便，精度不低于单光束莫尔偏折术。
With this method, the readout of information is convenient, the accuracy isn't lower than that single beam Moire deflectometry.
