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.
