Abstract
An optical subsystem of a near-eye display system provides for projecting light of a virtual image of image content to an eye location, and provides for collecting light of the virtual image onto an exit pupil on a surface proximate to an outer surface of an eye when at the eye location. A subpupil modulator within an aperture in cooperation with the optical subsystem provides for forming a plurality of subpupils within the exit pupil, provides for less than all of the light of the virtual image associated with one or more less than all of the plurality of subpupils to be projected to the eye location, and provides for individually and independently controlling an intensity of the light through each activated subpupil to a level less than a maximum level of intensity.
Claims28
1-3. (canceled)
A near-eye display system, comprising:
- a. an optical subsystem, wherein said optical subsystem provides for projecting light of a virtual image of image content to an eye location, and said optical subsystem provides for collecting said light of said virtual image propagating from an aperture of said optical subsystem onto an exit pupil on a surface proximate to an outer surface of an eye when said eye is at said eye location;
- and
- b. a subpupil modulator within said aperture, wherein said subpupil modulator in cooperation with said optical subsystem provides for forming a plurality of subpupils within said exit pupil, said subpupil modulator in cooperation with said optical subsystem provides for projecting to said eye location a portion less than all of said light of said virtual image associated with one or more less than all of said plurality of subpupils, and said subpupil modulator provides for individually and independently controlling an intensity of said light through each activated subpupil of said plurality of subpupils to a level less than a maximum level of intensity.
5-38. (canceled)
40-47. (canceled)
A near-eye display system as recited in claim 5, wherein said light of said virtual image is generated by a controllable light source of said subpupil modulator, said controllable light source of said subpupil modulator provides for separately and controllably illuminating or not illuminating each subpupil of said plurality of subpupils, said virtual image is generated by a flat-panel two-dimensional image-display modulation array of light-modulating image-display pixels that is illuminated by said controllable light source, and said optical subsystem comprises a catadioptric magnifier located between said flat-panel two-dimensional image-display modulation array and said exit pupil, wherein said catadioptric magnifier provides for collecting said light of said virtual image propagating from said subpupil modulator onto said surface of said exit pupil, wherein said controllable light source comprises a flat-panel two-dimensional light source array of light-emitters.

55-58. (canceled)
A method of projecting an image with a near-eye display system, comprising:
- a. projecting light of a virtual image of image content to an eye location;
- b. collecting said light of said virtual image propagating from an aperture of an optical subsystem onto an exit pupil on a surface proximate to an outer surface of an eye when said eye is at said eye location;
- c. providing for forming a plurality of subpupils within said exit pupil;
- d. projecting to said eye location a portion less than all of said light of said virtual image associated with one or more less than all of said plurality of subpupils;
- and
- e. controlling an intensity of said light through at least one subpupil of said plurality of subpupils to be different from an intensity of said light through at least one other subpupil of said plurality of subpupils, wherein the operation of controlling said intensity is responsive to a condition of an eye pupil of said eye when said eye is at said eye location.
