Abstract: A scanned retinal display includes an optical scanning array to generate multiple exit pupils in conjunction with an eyepiece. The multiple exit pupils expand the effective exit pupil. As a user moves their eye the eye moves from one exit pupil to another. A scanning array creates the multiple exit pupils to maintain a clear line of sight for an augmented display. Also, a viewer's eye position is tracked. To achieve a larger effective exit pupil and the pin hole effect advantage of a small exit pupil, only one exit pupil of the multiple pupils is active to enter the user's eye.

Abstract: A display device is achieved using a simplified optical system which generates an expanded exit pupil without compromising magnification or resolution. Modulated light from a source is converged toward a focal point by an optics subsystem. A scanning subsystem deflects the converging light, and thus the focal point, along a raster pattern to define an intermediate image plane. A lens array defines a surface which coincides with the image plane. The lens array includes a plurality of lenses and a polymer dispersed liquid crystal film. The film serves to spread incident light and thus form an expanded exit pupil.

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.
