Nowadays, a number of 3D shape measurement methods have been developed such as stereo vision, laser structured light, and Phase Measuring Profilometry (PMP). They have many problems such as correspondence problem, 2pi-ambiguity and occlusion problem. Among them, occlusion problem is common problem for 3D shape measurement and well known as difficult to solve. To solve this problem, we suggest a new sensing system based on optical scanning system and movable mirror system, which can change the viewing angle without changing of field-of-view (FOV), and can do the FOV with maintaining the viewing angle. The performance of our system is checked by simulation and a series of real experiments.
