Abstract
This paper summarizes our decade-long research efforts towards superfast 3D shape measurement leveraging the digital micromirror device (DMD) platforms. Specifically, we will present the following technologies: (1) high-resolution real-time 3D shape measurement technology that achieves 30 Hz simultaneous 3D shape acquisition, reconstruction and display with more than 300,000 points per frame; (2) Superfast 3D optical metrology technology that achieves 3D measurement at a rate of tens of kHz utilizing the binary defocusing method we invented; and (3) the improvement of the binary defocusing technology for superfast and high-accuracy 3D optical metrology using the DMD platforms. This paper will present both principles and experimental results.
