Abstract
A mixed-reality near-eye display system in a head-mounted display (HMD) device includes a display alignment tracker configured for monitoring virtual image pixels in binocular waveguide-based displays and providing adjustments to a display engine to reduce binocular and color misalignments that can occur from thermal expansion of HMD device components and mechanical shock and vibration during device use. Surface relief gratings, located on waveguide combiner plates guiding separate display colors, are configured to in-couple and guide virtual image light from a projector-based display engine and simultaneously out-couple light for the near-eye display and alignment tracking.
