Abstract
An optical device for an augmented reality or virtual reality display. A first input diffractive optical element is arranged on a waveguide to receive light from a projector, couple a first portion of the light into the waveguide along a first path, and allow a second portion of the light to pass through. A second input diffractive optical element is arranged to receive the second portion of the light and couple a third portion of the received light along a second path. An output diffractive optical element receives light along the first and second paths and couples the received light out of the waveguide towards a viewer at a first pattern of positions for light along the first path and at a second pattern of positions for light along the second path, providing a first and second plurality of exit pupils corresponding to the first and second pattern of positions.
