Abstract
A near-eye display system that employs a volume holographic element containing distinct but overlapped planar volume gratings, each corresponding to a subset of pixels in the display. The volume gratings are illuminated using light incident from angles, and at wavelengths, that match the conical diffraction conditions for each grating, thereby achieving both high diffraction efficiency and a wide field of view. A single volume grating can thus be used to display thousands of pixels independently with high efficiency.
