ABSTRACT
Once the 3D imaging system is developed, the next stage is toincrease its speeds. The measurement speed improvement involves both software and hardware, yet is fundamentally limited by hardware. Therefore, this chapter focuses on how to fundamentally achieve the highest-possible 3D imaging speed provided that the software processing can catch up with hardware. Specically, this chapter summarizes a decade long research eorts toward achieving high-speed 3D imaging leveraging the DMD platforms. We cover two milestones that have been reached over the course of more than a decade: the rst milestone was to achieve high-resolution real-time 3D imaging technology at video frame rate (e.g., 30Hz or better) including simultaneous 3D shape acquisition, reconstruction and display; and the secondmilestone was to develop the digital binary defocusing technology to perform 3D imaging at a rate of tens of kHz.
