Abstract
A waveguide display includes a light source, a conditioning lens assembly, a scanning mirror assembly, and a controller. The light source includes a plurality of source elements that are configured to emit image light in accordance with scanning instructions. The conditioning lens assembly transmits conditioned light based in part on the image light. The scanning mirror assembly scans the conditioned image light to particular locations as scanned image light in accordance with scanning instructions. The output waveguide includes an input area and an output area, receives the scanned image light emitted from the scanning mirror assembly at the input area, and outputs the expanded image light from a portion of the output area based in part on a direction of the expanded light output from the scanning mirror assembly. The controller generates the scanning instructions and provides the scanning instructions to the light source and the scanning mirror assembly.
