Abstract

A dual-plane head-mounted display system based on polarization-multiplexing is proposed. A metal wire grid polarizer is employed to separate the two orthogonal polarizations to different optical paths due to its excellent polarization-selective characteristics within large angle and spectrum ranges. System parameters including the curvatures of the reflective mirrors and the aspheric lens have been optimized to achieve good image quality within a field of view of ~50 degrees at different focal depths. Our system could provide correct depths for full-color 3D images, so that the vergence-accommodation conflict and visual fatigue problems could be solved.
