1. An optical assembly, comprising:
- a wedge optic including an input edge, an angled surface adjacent the input edge, and an unangled surface adjacent the input edge and opposite the angled surface; and
an LED lighting system optically coupled to the input edge;
wherein unmodulated light from the LED lighting system enters the wedge optic through the input edge;
wherein the angled surface reflects the unmodulated light out of the unangled surface to uniformly irradiate a reflective image display to produce an image of modulated light that is reflected back through the unangled surface and the angled surface to transfer optics.

Abstract
This disclosure concerns an interactive head-mounted eyepiece with an integrated processor for handling content for display and an integrated image source for introducing the content to an optical assembly through which the user views a surrounding environment and the displayed content, wherein the optical assembly comprises a light transmissive wedge-shaped illumination system with an LED lighting system coupled to an edge of the wedge, and wherein an angled surface of the wedge directs light from the LED lighting system to uniformly irradiate a reflective image display to produce an image that is reflected through the illumination system to provide the displayed content to the user.

8. An optical system, comprising:
-
a lighting system configured to generate unmodulated light; and a light transmissive wedge-shaped optic having an angled surface, an unangled surface, and an edge between the angled surface and the unangled surface, the light transmissive wedge-shaped optic positioned relative to the lighting system such that the unmodulated light from the lighting system enters the edge, and the angled surface reflects the unmodulated light out of the unangled surface to a reflective image display that reflects modulated light back through the unangled surface and the angled surface. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. An augmented reality display, comprising:
-
a lighting system configured to generate unmodulated light; a light transmissive wedge-shaped optic having an angled surface, an unangled surface, and an edge between the angled surface and the unangled surface, the light transmissive wedge-shaped optic positioned relative to the lighting system such that the unmodulated light from the lighting system enters the edge, and the angled surface reflects the unmodulated light out of the unangled surface to a reflective image display that reflects modulated light back through the unangled surface and the angled surface; and transfer optics configured to receive modulated light transmitted through the unangled surface and the angled surface of the light transmissive wedge-shaped optic and direct the modulated light to a viewing location. - View Dependent Claims (19, 20)
