Multibeam diffraction grating-based near-eye display
First Claim
1. A near-eye display comprising:
- a multibeam diffraction grating-based display configured to provide a plurality of different views of an image; and
an optical system configured to relay the plurality of different views of the image to a corresponding plurality of different locations within an eye box at an output of the near-eye display, the corresponding plurality of different locations within the eye box being configured to impart focus depth cues to a user of the near-eye display.

Abstract
A near-eye display and a binocular near-eye display system provide a plurality of different views of an image to different locations within an eye box to impart focus depth cues to a user. The near-eye display includes a multibeam diffraction grating-based display configured to provide the different views and an optical system configured to relay the different views to the different locations within the eye box. The binocular near-eye display system includes a pair of the multibeam diffraction grating-based displays and a binocular optical system configured to provide and relay a stereoscopic image pair representing a three-dimensional (3D) scene to a corresponding pair of laterally displaced eye boxes.

15. A near-eye binocular display system comprising:
-
a pair of multibeam diffraction grating-based displays, each multibeam diffraction grating-based display being configured to provide a different image of a pair of stereoscopic images representing a three-dimensional (3D) scene; and a binocular optical system configured to separately relay the different images of the stereoscopic image pair to a corresponding pair of eye boxes, the eye boxes being laterally displaced from one another, wherein a multibeam diffraction grating-based display of the display pair comprises a plate light guide and an array of multibeam diffraction gratings, a multibeam diffraction grating of the array being configured to diffractively couple out guided light from within the plate light guide as a plurality of coupled-out light beams, the coupled-out light beam plurality being configured to provide the different image of the stereoscopic image pair. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A method of near-eye image display operation, the method comprising:
-
guiding a collimated light beam in a light guide at a non-zero propagation angle; diffractively coupling out a portion of the guided collimated light beam from the light guide using a multibeam diffraction grating to produce a plurality of coupled-out light beams directed away from the light guide at different principal angular directions to form a light field, the light field providing a plurality of different views of an image corresponding to the different principal angular directions of the coupled-out light beams; and relaying the plurality of different views of the image to an eye box using an optical system. - View Dependent Claims (23, 24, 25)
