摘要：

This paper investigates the possibilities for improving the accuracy and the sensitivity of the projected fringe moire technique in combination with digital image processing. Several techniques for improving the accuracy of various moire methods are reviewed. The method of translation of the grating between exposures is investigated, both theoretically and experimentally. It is found that the sensitivity and accuracy can be increased by at least one order of magnitude using this method. Also the hills and valleys problem is easily solved by this method. © 1986 by ASME.
