Abstract
A frame supports a display apparatus against the head of a viewer. A projector fitted within the frame generates a beam of image-bearing light. A light guide coupled to a forward section of the frame has a waveguide, an in-coupling diffractive optic formed on the waveguide for directing image-bearing light beams into the waveguide, a turning optic formed on the waveguide for expanding the respective image-bearing light beams from the in-coupling diffractive optic in a first dimension, and an out-coupling diffractive optic formed on the waveguide for expanding the respective image-bearing light beams in a second dimension orthogonal to the first dimension and forming a virtual image within a viewer eyebox. A mount supports the light guide in front of the viewer and provides a hinge for angular adjustment of the waveguide with respect to the projector.
