ABSTRACT:
An augmented retinal scanning display device includes a multi-functional eyepiece. One function is to direct an image beam onto a viewer's eye. Another function is to correct the vision of the viewer's eye. The display is worn by a viewing person. The eyepiece includes a reflective surface and a transmissive surface. An image beam reflects off the reflective surface onto the viewer's retina enabling the viewer to perceive a virtual image. Background light, such as from the ambient environment or another display device, enters the eyepiece at the transmissive surface and passes through the eyepiece toward the viewer's eye. While passing through the eyepiece, the background light is refracted to correct the viewer's vision.
