Head mounted imaging apparatus with optical coupling

Last updated:

Abstract:

A head-mounted virtual image display apparatus has a projector that directs image-bearing light beams along a projection axis. A planar waveguide is configured to receive the image-bearing light beams through an input aperture and to form expanded image-bearing light beams that are output from an output aperture of the waveguide. An optical coupler is configured to receive the image-bearing light beams along the projection axis, to reorient the projection axis with respect to the waveguide, to rotate the image-bearing light beams about the projection axis, and to direct the rotated image-bearing beams along the reoriented projection axis through the input aperture of the waveguide.
