Abstract
A multi-planar plenoptic display assembly with multiple spatially-varying light emitting and modulating planes. The display assembly includes at least one light emitting device and may include a modulating device used in conjunction according to display methods taught herein to display light field data. A display assembly controller may be used to render a light field with depth into a multi-planar plenoptic display assembly by assigning decomposed portions of the light field to the display assembly for display or presentation by differing ones of the emitting elements and by operating a modulating device to provide a parallax barrier. In one embodiment, a projector is used with bi-state screens. In another embodiment, two automultiscopic displays (either parallax barrier or lenticular lenses) are overlaid with a beam splitter. In a further embodiment, an oscillating mirror is used to temporally and optically move one automultiscopic layer (either parallax barrier or lenses) through space.
