Design of high-performance geometric waveguide head-mounted displays
摘要
Abstract
To satisfy augmented reality(AR)optical waveguide requirements for a large field of view(FOV),thin and lightweight form factor,and high immersion,a mass-producible thin-lightweight trans-missive head-mounted display(HMD)optical system based on an arrayed geometric thin-film waveguide architecture was designed and implemented.The system comprises an eyepiece,an arrayed waveguide module,and an illumination module.The arrayed waveguide employs an array of semi-transparent,semi-reflective films with customized angle-selective coatings as the optical combiner,enabling pupil expansion.A dual-waveplate polarization-mixing scheme was introduced,improving display uniformity from 59.66%to 61.12%under single-polarized illumination and to 76.61%in practical measurements.Through com-prehensive optical simulation and system-level optimization,and supported by a mature domestic optical manufacturing chain-including precision cutting,grinding and polishing,vacuum deposition of complex multilayer films,and high-precision bonding-together with an added waveplate lamination process,key technical barriers limiting the mass production of arrayed waveguides were overcome.A prototype was fabricated,and mass production was achieved.The proposed approach resolves the longstanding trade-off between optical performance and manufacturability in AR HMDs,supporting both consumer and industrial applications.关键词
