Abstract
A near-eye system includes a display waveguide, an eye-tracking waveguide, and a scanner. The display waveguide is configured to present a virtual image to an eyebox region. The eye-tracking waveguide is configured to illuminate the eyebox region with illumination light. The scanner is configured to be driven to varying image scan angles to direct image light to the display waveguide to present the virtual image to the eyebox region. The scanner is also configured to be driven to one or more alignment scan angles to sense an alignment between the display waveguide and the eye-tracking waveguide.
