Abstract

A dynamic time multiplexed holographic system including a holographic screen and a projector that projects successive perspective images onto the holographic screen. The projector includes a rotating polygon that provides successive image slices to the holographic screen and a spatial light modulator that provides successive image slices to the rotating polygon. The holographic screen refracts the successive perspective images perpendicular to the holographic screen.
