Advanced Multiscopic Display via Temporal Multiplexing

摘要

Recent advances in the framerate of deformable mirror devices (DMDs) coupled with a corresponding increase in the rendering and data transfer capabilities of graphical processing units (GPUs) has lead to the greatly increased viability of temporal multiplexing approaches for 3d display technology. Employing these advances an initial proof of concept four-zone multiscopic display has been demonstrated, with a 8-16 zone large format display in development. Both designs employ a high-speed LCD shutter located at the pupil of the optical train synchronized with a high framerate DMD projector allowing for the formation of multiple viewing zones via persistence of vision. Present results and ongoing progress in the design of the optical train, high speed projector and the associated rendering system.
