To measure an object shape in time series, a high-speed shape measurement technique is requested. The sampling moire method gives the phase information of the grating from a one-shot grating image. The captured image is analyzed by performing easy image processing, i. e., thinned-out and linear interpolation, to obtain the multiple phase-shifted moire patterns. Then, the phase distribution of the moire pattern can be calculated using phase-shifting technique. In this paper, we proposed a stereoscopic shape measurement for high-speed rotating object using one-shot phase-shifting sampling moire method. The principle and the experimental result are shown.
