Abstract:
1. A compact near eye display for generating a virtual image comprising: a modulatable light source that generates one or more pixels of an intended image, the modulatable light participating in the formation of a first dimension of the intended image as a linear arrangement of pixels, a focusing optic that angularly transforms the first dimension of the intended image from the linear arrangement of the pixels to an angular arrangement of pixel beams converging through a first dimension pupil within an eyebox, a scanning optic that directs the angularly transformed first dimension of the intended image from the focusing optic into a waveguide for conveying the angular arrangement of pixel beams to the first dimension pupil, the scanning optic being adjustable in synchronism with the modulatable light source for angularly forming a second dimension of the intended image as an overlapping angular arrangement of the pixel beams within a second dimension pupil in advance of the eyebox, and the waveguide being arranged to at least partially preserve the second dimension pupil so that the second dimension pupil as preserved sufficiently overlaps with the first dimension pupil within the eyebox so that the virtual image is viewable within the eyebox.
