Wearable image display system
First Claim
1. A wearable image display system comprising:
- a frame;
a first and a second light engine configured to generate a first and a second set of beams respectively, the beams substantially collimated within each set so that the first and the second set form a first and a second virtual image respectively, the light engines mounted on the frame at a first angle relative to a vertical plane; and
a first and a second optical component mounted on the frame at a different angle than the first angle relative to the vertical plane, the first and the second optical components comprising respective incoupling structures, respective fold structures configured to manipulate spatial distributions of the first and the second set of beams within each optical component, and respective exit structures, where the respective incoupling structures are configured to receive the first and the second set of beams and the respective exit structures are configured to guide the first and the second sets of beams onto eyes of a wearer of the wearable image display system.

Abstract
A wearable image display system includes a headpiece, a first and a second light engine, and a first and a second optical component. The first and second light engines generate a first and a second set of beams respectively, each beam substantially collimated so that the first and second set form a first and a second virtual image respectively. Each optical component is located to project an image onto a first and a second eye of a wearer respectively. The first and second sets of beams are directed to incoupling structures of the first and second optical components respectively. Exit structures of the first and second optical components guide the first and second sets of beams onto the first and second eyes respectively. The optical components are located between the light engines and the eyes. Both of the light engines are mounted to a central portion of the headpiece.
