Scanned retinal display with exit pupil selected based on viewer's eye position
First Claim
1. A method for generating a virtual image for viewing by a user in a scanning display that includes a plurality of scanners, comprising the steps of:
- modulating a beam of light according to image information;
detecting a viewing location of a user'"'"'s eye;
responsive to the detected viewing location, selecting a first scanner of the plurality of scanners; and
directing a first portion of the modulated beam of light to the selected first scanner.

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.
