Abstract

Augmented reality (AR) has attracted great attention from academia and industry for its potential applications in diversified fields. In order to eliminate the accommodation-vergence conflict in AR display systems, which causes 3D visual fatigue after prolonged use, several approaches have been proposed. This paper presented three types of true three-dimensional (3D) AR display techniques. The first is multi-plane volumetric display based on liquid crystal (LC) devices. We utilized fast switching polymer stabilized LC (PSLC) scattering films and polarization selective cholesteric LC (CLC) reflective films, respectively, realizing magnified 3D images augmented on the real world. The second is holographic display based on two holographic optical elements (HOEs), functioning as an optical combiner, an ocular lens and a beam expander simultaneously. For the third technique, we proposed two super-multi-view display approaches based on polarizing glasses and geometry phase optical elements (GPOEs), respectively.
