%X A Shearing Moire Interferometry is proposed. 3-D displacement informations are recorded on the same plate by double-exposure method. Carrire introduced to the beams in their first diffraction orders are changed between two exposures. Optical filtering and shearing techniques are applied to extracting the contour maps of 3-D displacement derivatives. Rigorous theoretical analyses are given. Demonstration experiment are conducted successfully and in-plane and out of plane displacement derivatives are obtained simultaneously.
