Large-volume, multiplane Fresnel holography for 3D displays
ORAL
Abstract
Digitally synthesized holograms, or computer generated holograms (CGHs) offer the possibility of dynamic projection for 3D displays [1]. There has been extensive efforts for such 3D video applications, however, available methods remain limited to projections to a few planes, over a narrow depth-of-field or with low-resolution. Overall, there is no technique that allows creation of a large number of consecutive projections with full depth control, and practical implementation of realistic 3D projections appears to be out of reach. Here we demonstrate a novel approach, which enables truly 3D reconstruction with full depth control and large-volume. We achieve high-contrast, high-quality multiplane images with low crosstalk. Our algorithm allows projection to 300 planes from a single hologram, advancing the state of the art by nearly two orders of magnitude, constituting in an unprecedented 3D projection capability. Further, our simulations demonstrate 3D projection of a complex object that can be viewed over the entire 4PI solid angle. Experimentally, we show a 3D display prototype, projecting 12 back-to-back images using a single hologram.
