A 3D video stream display architecture hybrid MEM/CMOS SIMD-parallel indexed swept-volume 3D displays

摘要

We describe the architecture of a three-dimensional image display comprised of a helical surface, which is kept rotating about its axis. The images are projected by means of a high performance digital mirror array, working in a SIMD parallel mode. The optical ray emanating from each mirror would intersect with the rotating surface at a 3D point whose 3D position is determined by the exact time of the emission. Recent advancements in microelectromechanical systems (MEMS), micro opto electromechanical systems (MOEMS) and CMOS fabrication processes offer the potential to fabricate these SIMD steerable high performance mirror arrays with in situ memory. We focus on the architecture of a scalable video stream display, in which the end user consumption may vary from a simple television to a multiview visualization of 3D dynamic events.
