Abstract:
1. An apparatus comprising: a light guide including a proximal end, a distal end, a front surface and a back surface spaced apart from the front surface, an ambient input region on the front surface near the distal end, and an output region on the back surface near the distal end; a beamsplitter having a plurality of faces, wherein one face of the beamsplitter is optically coupled to the proximal end of the light guide; a display optically coupled to another face of the beamsplitter; a projector assembly optically coupled to a face of the beamsplitter opposite the beamsplitter face that is optically coupled to the proximal end of the light guide, wherein the projector assembly comprises: a reflecting element having optical power positioned at the distal end of the light guide; and a distal optical element positioned in the light guide near the distal end, the distal optical element optically coupled to the beamsplitter, the ambient input region, the output region, and the reflecting element.
