Abstract

A new method of 3-D shape measurement by moire technique is presented. An interferometer and computer were used instead of gratings to obtain moire contour. The principle of it is theoretically analyzed in detail. In order to obtain moire contour without unwanted patterns, we propose a method of obtaining moire contour by XOR logic using a computer. Experimental results are given.
