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.
