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. The optical assembly includes a light transmissive wedge-shaped illumination system with angle selective coatings and an LED lighting system coupled to an edge of the wedge. 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.
1. A system, comprising: an interactive head-mounted eyepiece worn by a user, wherein the eyepiece includes an optical assembly through which the user views a surrounding environment combined with displayed content, an integrated processor for handling content for display to the user, and an integra
1. A system, comprising: an interactive head-mounted eyepiece worn by a user, wherein the eyepiece includes an optical assembly through which the user views a surrounding environment combined with displayed content, an integrated processor for handling content for display to the user, and an integrated image source for introducing the content to the optical assembly,wherein the optical assembly comprises a planar illumination facility including a light transmissive wedge with angle selective reflective and transmissive coatings and an LED lighting system coupled to the wedge, andwherein light from the LED lighting system undergoes multiple internal reflections from surfaces of the wedge and the coatings until the light reaches an angle where the coatings become transmissive and a portion of the light is transmitted to uniformly irradiate a reflective image display to produce an image that is reflected through the planar illumination facility to provide the displayed content to the user. 2. The system of claim 1, wherein the planar illumination facility further comprises a second wedge with a plurality of angle selective reflective and transmissive coatings between the wedge and the second wedge. 3. The system of claim 1, wherein the angle selective reflective and transmissive coatings are coatings selected from the group consisting of silicon dioxide and niobium pentoxide. 4. The system of claim 1, wherein a polarizing layer is disposed on the angled surface of the wedge. 5. The system of claim 1, wherein a polarizing layer is disposed on the LED lighting system. 6. The system of claim 1, wherein the planar illumination facility utilizes a wedge configuration with the wedge comprising a plurality of angle selective reflective and transmissive coatings on an angled surface of the wedge and on an outer surface of the wedge between the wedge and the reflective image display. 7. The system of claim 1, wherein the wedge has one angle from about 1 to 1.5 degrees. 8. A system, comprising: an interactive head-mounted eyepiece worn by a user, wherein the eyepiece includes an optical assembly through which the user views a surrounding environment and displayed content, an integrated processor for handling content for display to the user, and an integrated image source for introducing the content to the optical assembly,wherein the optical assembly comprises a planar illumination facility including a light transmissive wedge with angle selective reflective and transmissive coatings and a laser lighting system coupled to the wedge, andwherein light from the laser lighting system undergoes multiple internal reflections from surfaces of the wedge and the coatings until the light reaches an angle where the coatings become transmissive and a portion of the light is transmitted to uniformly irradiate a reflective image display to produce an image that is reflected through the planar illumination facility to provide the displayed content to the user. 9. The system of claim 8, wherein a plurality of laser light sources from the laser lighting system are coupled directly to an edge of the planar illumination facility. 10. The system of claim 8, wherein a cone of light from each of a plurality of laser light sources causes transmission of the light along a length of the wedge to produce uniform illumination of the reflective image display. 11. The system of claim 10, wherein light from the cone of light is reflected from an internal surface of the wedge to the angle selective reflective and transmissive coatings along the length of the wedge to produce uniform illumination of the reflective image display. 12. The system of claim 8, wherein at least one of the angle selective reflective and transmissive coatings is adapted to reflect light of a specific wavelength over a range of angles until a transmissive angle is reached. 13. The system of claim 8, wherein the angle selective reflective and transmissive coatings are coatings selected from the group consisting of silicon dioxide and niobium pentoxide and are placed on an angled surface of the wedge and on an exit surface of the wedge. 14. A system, comprising: an interactive head-mounted eyepiece worn by a user, wherein the eyepiece includes an optical assembly through which the user views a surrounding environment and displayed content, an integrated processor for handling content for display to the user, and an integrated image source for introducing the content to the optical assembly,wherein the optical assembly comprises a planar illumination facility including a light transmissive wedge with angle selective reflective and transmissive coatings and a lighting system coupled to the wedge,wherein light from the lighting system undergoes multiple internal reflections from surfaces of the wedge and the coatings until the light reaches an angle where the coatings become transmissive and a portion of the light is transmitted to uniformly irradiate a reflective image display to produce an image that is reflected through the planar illumination facility to provide the displayed content to the user and wherein the lighting system is selected from the group consisting of an LED lighting system and a laser lighting system. 15. The system of claim 14, wherein the lighting system comprises red, green and blue sources of light. 16. The system of claim 14, wherein light sources from the lighting system are directly coupled to an edge of the wedge. 17. The system of claim 14, wherein the planar illumination facility comprises the wedge and further comprises a second wedge coupled to the wedge with a plurality of the angle selective reflective and transmissive coatings. 18. The system of claim 17, further comprising a second plurality of the angle selective reflective and transmissive coatings on a side of the wedge facing the reflective image display. 19. The system of claim 14, wherein the lighting system includes a source of white light.
