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 1):
A display apparatus for displaying augmented reality images to a viewer, said display apparatus comprising:\n a display source that generates a field of image-bearing light from a surface; a lens spaced apart from the display source, said lens having a concave refractive surface and having a concave reflective surface; and a beam splitter plate disposed in free space in the optical path between the display source and the lens, such that an object scene can be viewed by the viewer through the beam splitter plate, said beam splitter plate having first and second substantially parallel surfaces that are oblique to a line of sight of the viewer, wherein 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 and such that the line of sight of the viewer for the object scene extends through beam splitter plate, 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; and (iii) the beam splitter plate has a length between 100 mm and 170 mm.
