Augmented imaging using a silhouette to improve contrast

Abstract
An augmented display includes an image display source and a silhouette display source. The image display source generates a virtual image to be perceived by a viewer. The silhouette display source occurs in the path of the background light. The silhouette display source generates a mask corresponding to the image content of the image display. The mask is a darkened area reducing or blocking background light. As the light from the virtual image is overlaid onto the background, there is less background light in the portion where the image appears.

Scanned retinal display with exit pupil selected based on viewer's eye position

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.
