1. A system (100) for displaying an image (880) to a user (90), said system (100) comprising:
- an illumination assembly (200) that provides for supplying a plurality of light (800);
an imaging assembly (300) that provides for creating an interim image (850) with said plurality of light (800); and
a projection assembly (400) that provides for creating said image (880) by modifying said interim image (850), said projection assembly (400) including an aspheric lens (450), wherein said aspheric lens (450) is a sixth order aspheric lens (454);
wherein said system (100) provides the user (90) a horizontal field of view (862) that is greater than about 60 degrees.

Abstract
A system (100), apparatus (110), and method (900) for displaying an image (880). The system (100) can use an aspherical lens (450) to direct light (800) in the interim image (850) towards the viewer (96) of the final image (880) displayed by the system (100). Use of the aspherical lens (450) expands the FOV (860) accessible to the viewer (96) and reduces exit pupil drift (480).

13. A system (100) for displaying an image (880) to a user (90), said system (100) comprising:
-
an illumination assembly (200) that provides for supplying a plurality of light (800); an imaging assembly (300) that provides for creating an interim image (850) with said plurality of light (800); and a projection assembly (400) that provides for creating said image (880) by modifying said interim image (850) comprised of said plurality of light (800), wherein said projection assembly (400) includes an aspheric lens (450) that reduces a pupil drift (470) in said image (880); wherein said system (100) is a VRD apparatus (116) that provides the user (90) with a horizontal field of view (862) that is greater than about 60 degrees. - View Dependent Claims (16, 17, 18, 19)

14. A method (900) for making an image (880) accessible to a user (90) by projecting said image (880) on an eye (92) of the user (90), said method comprising (900):
-
generating (910) a plurality of light (800) from a light source (210); modulating (920) said light (800) into an interim image (850); and directing (930) said light (800) of said interim image (850) in an aspheric lens (450), wherein said aspheric lens (450) is a sixth order aspheric lens (454), prior to the delivery of said light (800) to the eye (92) of the user (90); wherein said system (100) provides the user (90) a horizontal field of view (862) that is greater than about 60 degrees. - View Dependent Claims (15)
