Abstract:
An optical apparatus for display to a viewer has a concave spherical mirror that has a center of curvature at the viewer's pupil and that has a second radius of curvature. An image generation apparatus forms an image onto a spherical diffusive surface, wherein the spherical diffusive surface has a first radius of curvature that is substantially half the length of the second radius of curvature. A beam splitter is positioned along a principal axis of the concave spherical mirror and optically disposes the curved diffusive surface at the focal surface of the concave spherical mirror.

Claim (Index 20):
A head-mounted display apparatus comprising a left image forming apparatus and a right image forming apparatus, respectively, for display to each left and right pupil of a viewer, each image forming apparatus comprising:\n a) a laser light source that directs modulated laser light along an optical axis; b) a scanning apparatus that comprises:\n (i) a focusing lens that defines a focal point along the optical axis; \n (ii) a scanning mirror that is actuable to fold the optical axis and scan the focal point across a spherically curved diffusive surface; \n and c) a beam splitter that is disposed to direct scanned light from the diffusive surface toward a concave spherical mirror, wherein the spherical mirror has a first center of curvature at the corresponding pupil of the viewer, wherein the curved diffusive surface is disposed along a focal surface of the spherical mirror and has a second center of curvature at the scanning mirror, wherein, with respect to the spherical mirror, each corresponding pupil of the viewer is optically conjugate to the corresponding scanning mirror through the beam splitter.
