Stanford and Meta Reveal 3-Millimeter Mixed-Reality Glasses Delivering True Holographic Visuals

Researchers are tackling remaining optical challenges to gear the 3 mm-thick glasses toward market readiness.

Overview

  • The prototype integrates custom waveguides and spatial light modulators in a 3 mm-thick frame to project full light-field holograms.
  • An AI-driven calibration system manages étendue by balancing a wide field of view with a large eyebox for natural eye movement without image distortion.
  • The display reconstructs the entire light field rather than relying on stereoscopic images, enabling more realistic depth and 3D immersion.
  • The ultra-thin optical stack is designed for all-day wear to reduce neck and eye strain compared to bulky headsets.
  • The research team is preparing for product development as it continues refining optics and pursues a “Visual Turing Test” goal of visuals indistinguishable from reality.
