Abstract

This paper explores how Liquid Crystal (LC) technologies can enable the metaverse by enhancing Augmented Reality (AR)/Virtual Reality (VR) optics. We highlight the potential of Liquid-Crystal Polarization Holograms (LCPHs) developed by Reality Labs Research (RLR) at Meta Platforms, Inc. LCPHs offer compact, lightweight solutions with versatile optical capabilities, including eye-tracking, accommodation, compact VR viewing optics with improved image quality, AR waveguide combiners with enhanced efficiency, and simplified fabrication processes. These advancements show promising potential to make a real impact in the AR/VR industry. LC technologies, especially LCPHs, are paving the way for more comfortable and immersive AR/VR viewing experiences.
