Abstract

An imaging apparatus (100) for providing an image from a display (106) to an observer (101), comprising: a display (106) generating an optical output, an imaging surface member (109) constructed and arranged for viewing by said observer, and a scanning mirror/lens assembly (102) optically interposed between the display and the imaging surface member, and constructed and arranged to motively repetitively scan the display, generate a scanned image, and transmit the scanned image to the imaging surface member, for viewing of the scanned image. Various field emitter display designs and subassemblies are described, which may be usefully employed in such imaging apparatus.
