Abstract:
A near-eye display has an image projector coupled to a lightguide for receiving and propagating image light provided by the image projector, the image light carrying an image to be displayed to a viewer. Field of view of the near-eye display may be expanded by providing a beam redirector downstream of the lightguide for controllably redirecting the image light m coordination with displaying different field of view portions by the image projector. To compensate the redirection of external light by the beam redirector, a second beam redirector may be provided upstream of the first redirector and the lightguide.
