Personal Display Using an Off-Axis Illuminator
First Claim
1. A head mounted display for displaying images that can be viewed by a wearer when said display is worn on the wearer'"'"'s head, said display comprising:
- a spatial light modulator comprising an array of pixels selectively adjustable for producing spatial patterns, said array of pixels defining a substantially planar reflective surface on said spatial light modulator;
a light source;
illumination optics disposed to receive light from the light source and direct light onto the planar reflective surface of said spatial light modulator at an angle with respect to the surface normal of said planar reflective surface;
imaging optics disposed with respect to the spatial light modulator to receive light from said spatial light modulator;
a curved reflector disposed to reflect light from said imaging optics so as to form a virtual image such that said image may be viewed by an eye of the wearer; and
headgear for supporting said spatial light modulator, imaging optics, and reflector, wherein only rays of light incident on said planar reflective surface of said spatial light modulator at an angle with respect to said surface normal of said planar reflective surface contribute to said virtual image viewable by said eye.

Abstract
Certain embodiments include a head mounted display for displaying images that can be viewed by a wearer when the display is worn on the wearer'"'"'s head. The display can include a spatial light modulator having an array of pixels selectively adjustable for producing spatial patterns. The array of pixels can define a substantially planar reflective surface on the spatial light modulator. The display can further include a light source. The display can also include illumination optics disposed to receive light from the light source and direct light onto the planar reflective surface of the spatial light modulator at an angle with respect to the surface normal of the planar reflective surface. The display can include imaging optics disposed with respect to the spatial light modulator to receive light from the spatial light modulator. The display can further include a curved reflector disposed to reflect light from the imaging optics so as to form a virtual image such that the image may be viewed by an eye of the wearer. The display can also include headgear for supporting the spatial light modulator, imaging optics, and reflector. In certain embodiments, only rays of light incident on the planar reflective surface of the spatial light modulator at an angle with respect to the surface normal of the planar reflective surface contribute to the virtual image viewable by the eye.

26. A head mounted display for displaying images that can be viewed by a wearer when said display is worn on the wearer'"'"'s head, said display comprising:
-
a plurality of pixels selectively adjustable for producing spatial patterns;
imaging optics disposed with respect to the plurality of pixels to receive light from the plurality of pixels, the imaging optics comprising a plurality of lenses;
