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 21):
A display apparatus comprising\n a) a flat display surface that emits image-bearing light; b) a left image forming apparatus and a right image forming apparatus for display to each left and right pupil of a viewer, respectively, each image forming apparatus comprising:\n (i) a concave spherical mirror that has a center of curvature optically conjugate to the corresponding viewer's pupil and that has a second radius of curvature; \n (ii) a fiber optic faceplate having a planar light entry surface that seats against the flat display surface and having a curved imaging surface, opposite the entry surface, that forms a spherically curved image field from the emitted image-bearing light, \n wherein the curved imaging surface has a first radius of curvature that is substantially half the length of the second radius of curvature; \n and c) a beam splitter that is positioned along a principal axis of each concave spherical mirror and that optically disposes the corresponding curved imaging surface at the focal surface of the concave spherical mirror for the left and right image forming apparatus.
