一种新的光栅投影轮廓术
A Novel Profilometry with Projecting Grating
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伏。在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.
