Abstract
A compact near eye display generates image segments for a first dimension of an intended image. Each of the image segments is transformed into angularly distinguished beamlets that converge through a first dimension pupil within an eyebox. A scanning optic angularly separates the angularly distinguished beamlets of different image segments for creating a second dimension pupil. The angularly distinguished and separated beamlets propagate along a waveguide in a form that minimizes the thickness of the display in front of a viewer's eye and limits the overall size of the optics required to support the projection of virtual images into the viewer's eye.
