A Novel Profilometry with Projecting Grating
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.
