In this paper, theory and application of phase-shifting shadow moire topography is focused on the non-contact measurement of object surface for practical use in the field of production engineering. Shadow moire topography has been studied during last few decades in the area of the optical physics and mathematical theory has now been established. But in case of the classical shadow moire topography, the sensitivity is a few tenths of millimeter in best cases. Here we propose one trial to apply phase-shifting method to conventional shadow moire topography. Generally, it is difficult to use a phase-shifting method in shadow moire because it is impossible to obtain uniform phase shifts on the whole field. But in this paper, we use the fact that if the depth of object is much less than the distance between the observer and the master grating, and the object is displaced perpendicularly to the grating plane, phase shifts are almost uniform. Finally we obtained a better result by using this procedure and applied the phase-shifting shadow moire to three dimensional object shapes reconstruction.
