Abstract
A near-eye display system includes a display panel to present image frames to the eyes of a user for viewing. The system also includes a beam steering assembly facing the display panel that is configurable to displace a light beam incident on the beam steering assembly, thereby laterally shifting light relative to an optical path of the light beam incident on the beam steering assembly. The beam steering assembly includes a birefringent plate configurable to replicate a light ray incident on the beam steering assembly such that the replicated light ray is laterally shifted relative to an optical path of the light ray incident on the beam steering assembly.
