Beschreibung
Zusammenfassung:	A system for projecting light, the system comprising a light generator that generates image light that corresponds to a series of images; a display device that receives the image light generated by the light generator; an acousto-optical scanner, wherein the display device deflects the image light onto the acousto-optical scanner and the acousto-optical scanner deflects portions of the image light onto a plurality of diffractive optical elements, wherein each of the plurality of diffractive optical elements corresponds to a different depth plane of the series of images, wherein the acousto-optical scanner is configured to generate first surface acoustic waves to deflect portions of the image light in a first direction, and wherein the acousto-optical scanner is configured to generate second surface acoustic waves to deflect portions of the image light in a second direction.
