#$%^&*AU2016200961B220160512.pdf#####ABSTRACT A display system includes an optical component having a first and second surface, wherein the first surface comprises a diffractive optical element, and a projector system to create a projected image on the optical component. The projector includes an illumination source that emits electromagnetic radiation within a predetermined spectral band, an image generator that ascribes image characteristics to the radiation, and an optically-powered component that directs the radiation at the first surface of the optical component. The diffractive optical element reflects at least a portion of the radiation in a predetermined direction. The optical component has zero optical power for transmitted light. The optical component transmits at least a portion of the ambient scenery within a predetermined spectral band within a field-of-view of the projected image. The projected image maintains substantial boresight alignment with the ambient image.WO 2013/070770 PCT/US2012/063948 1/3 100 FIG. 1 102 122 12412 -- 112 120 110 106 108 240 250 220 200 FIG. 2 270 /230 210 260
