Polarization-dependent combiner for wide Field-of-View glasses-like AR displays

A glasses-like augmented reality (AR) display with an extended field-of-view (FOV) using a liquid crystal polarization-dependent combiner (PDC) is proposed. The novel PDC consists of two polarization-selective volume lenses (PVLs) that can control the beam path depending on the polarization states. The viewing angle limited by the system etendue can be extended twice. Besides, the PVL is based on patterned liquid crystal which can be thin and flat. The proposed configuration provides a promising solution for the limited FOV issue in glasses-like AR displays.
