Paper Abstract

The technique of retroreflective grating analysis is presented to measure surface contour. This noncontacting optical method can detect a dent with maximum depth less than 10 mm. A comparison with some physical measuring systems indicates that it has advantage over such contacting measurements, especially for specular surfaces.
