Video see-through super multi-view near eye display using waveguide-type light source and ferroelectric liquid crystal on silicon

Abstract

A novel design of a video see-through super multi-view near-eye display (VST-SMV-NED) with a waveguide-type light source (WLS) and a ferroelectric liquid crystal on silicon (FLCoS) is proposed. The proposed method presents threedimensional (3D) scenes by projecting the SMV images of deep depth of field into the eye pupil. A temporal multiplexing scheme is adopted to deliver the SMV images within an eye integration time (>30Hz), allowing flicker-free 3D image presentation. Real-world stereo images are captured by a stereo camera and transformed into SMV images. The SMV images of virtual digital images and real-world scenes are merged into augmented reality (AR) SMV scenes, creating VST type 3D AR scene. We experimentally demonstrated the feasibility of the proposed method by displaying VR SMV images on the FLCoS with the WLS illumination.
