Abstract

Higher accuracy and reliability are indispensable especially in the field of industrial 3D measurement applications. 3D measurement based on the phase shifting technique applies to various applications of imaging system. We developed a DMD projector for the projection of fringe patterns for the phase shifting technique. A DMD projector has a lot of advantages compared with other devices such as LCD. We focus on the specifications of speed, intensity linearity and brightness of the DMD. We show, in this paper, our DMD-based 3D measurement system satisfies requirements which come from industrial applications, and also show two representative applications and feasibility of our phase shifting system to these applications.
