Abstract
A near-eye display of a type having an image generator for generating a succession of angularly related beams and waveguide for propagating the angularly related beams to an eyebox within which a virtual image is visible includes a controllable output aperture for such purposes as reconstructing a better defined pupil within the eyebox while also preserving the possibility for viewing the ambient environment from the eyebox through the controllable output aperture.
