| 摘 要： | 提出了一种新的光学全场轮廓术，它采用了一种可由计算机控制的，可变空间频率的莫尔条纹投影仪，利用不同空频的两次变精度测量，以适应待测物体形面的突然起。以以上理论基础以及一台具体实验装置的配合下，得到出了令人满意的测量结果。

| Abstract: | A novel optical whole field profilometry is presented. A new kind of moire fringe projector controlled by computer is used for changing the spacial frequency to adapt the contour of the object to be measured. Besides, a method named “Two Times Measurement with Different Precisions” is proposed in order to measure an object with sudden surface changes. The satisfactory results are obtained. |
