Abstract: |
Spectacle-mounted display apparatus in which a reflective surface of a partially-transparent eyeglass lens is employed as the primary optical element. A concave spherical relay reflector is positioned inside the lens/eye cavity. The display ocular is an asymmetrical multi-axial virtual image magnifier which receives the object light on its relay reflector and thereby reflects the object light from the partially reflective surface of the spectacle lens to the wearer's eye to form a virtual image at infinity. In various embodiments of the invention, the ocular display apparatus is employed as a personal display of film, LEDs, fiber optics, CRT or electronic images generated for delivering data to a wearer as a virtual image at infinity.

First Claim:

The invention claimed is:
1. Ocular display apparatus comprising:
- spectacles including a frame for mounting on a wearer's head and at least one lens carried by said frame for positioning in spaced alignment with a wearer's eye on a central axis for defining a cavity between said lens and the wearer's eye said central axis generally corresponding to a wearer's natural forward line of sight, said lens having at least one surface which is concave with respect to said cavity and being of partially reflective construction,
- means for radiating an optical image in the form of an objective image into said cavity from a direction generally orthogonal to said central axis, and
- a relay mirror positioned within said cavity for intercepting and reflecting said visible objective image onto said lens surface, and being reflected by said lens surface to a wearer's eye to form a virtual image of said radiating means of infinity.
