Abstract:
A display apparatus has an image generator that generates image-bearing light from a f surface and a lens spaced apart from the image generator and having an aspheric incident refractive surface concave to the image generator and having an aspheric reflective surface concave to the image generator, wherein a principal axis of the reflective surface is normal to the image generator. A beam splitter plate disposed in free space between the image generator and the lens has first and second parallel surfaces that are oblique to a line of sight of a viewer. The lens and the beam splitter plate define a viewer eye box for the image-bearing light along the line of sight of the viewer.

Claim (Index 26):
A display apparatus comprising:\n a) a flat display source; b) a lens spaced apart from the display source and having a concave refractive surface and a concave reflective surface, and c) a beam splitter plate disposed in an optical path between the display source and the lens and along a line of sight of a viewer viewing a real-world object scene, the beam splitter plate having first and second parallel surfaces oblique to the line of sight of the viewer, wherein the beam splitter plate is further disposed to provide image-bearing light from the display source to the lens, and wherein the beam splitter plate and lens define the optical path that conveys the image-bearing light for a first refraction through refractive surface, reflects the refracted light from the reflective surface, and refracts the reflected light from the refractive surface back to the beam splitter, said beam splitter plate provides the light toward a viewer along the line of sight of the viewer, and wherein: (i) the focal length of the lens is between 38 mm and 64.7 mm; (ii) said display apparatus defines a horizontal field of view H, wherein 30 degrees \u2264H\u226460 degrees; (iii) the beam splitter plate has a length that is between 100 mm and 170 mm.
