Dual-depth augmented reality display with reflective polarization-dependent lenses

Abstract

Vergence-accommodation conflict (VAC) is a common annoying issue in near-eye displays using stereoscopy technology to provide the perception of three-dimensional (3D) depth. By generating multiple image planes, the depth cues can be corrected to accommodate a comfortable 3D viewing experience. In this study, we propose a multi-plane optical see-through augmented reality (AR) display with customized reflective polarization-dependent lenses (PDLs). Leveraging the different optical powers of two PDLs, a proof-of-concept dual-plane AR device is realized. The proposed design paves the way to a compact, lightweight, and fatigue-free AR display.
