Abstract

A near-eye display includes a compound waveguide for presenting viewers with virtual images visible within an eyebox at a limited relief distance from the compound waveguide. The compound waveguide is assembled from a plurality of waveguides that are at least partially optically isolated for conveying different portions of the virtual image. An input couple injects the different portions of the virtual image into predetermined combinations of the waveguides, and an output coupling ejects the different portions of the virtual image from the waveguides toward the eyebox in a form that at least partially constructs a pupil within the eyebox.
