Abstract
An optical display includes a waveguide comprising an input coupler, first expansion grating, second expansion grating, and output coupler. The input coupler is configured to couple image light from an image source. The first expansion grating is configured to receive the image light, expand the image light along a first axis and away from a first direction at a first angle of expansion, and direct the image light out of the first expansion grating in a second direction different than the first direction. The second expansion grating is configured to receive the image light, to expand the image light along the first axis and towards the first direction at a second angle of expansion, and direct the image light out of the first expansion grating in the second direction.
