Abstract : The report describes the analysis, experimental development, and test of the new HoloFacet (TM) scanning technique for high speed optical scanning and recording of 100 lp/mm at 100 MHz on a high resolution photographic film. The HoloFacet scanning technique employs the rotation of a HoloFacet within a coherent optical field, such that the resulting diffracted waves are scanned across a film surface as a succession of rapidly moving focal points. The HoloFacets are applied by well-developed holographic means to a surface which reduces the optical perturbation of the high speed system. The report also describes the transformation of the 'brassboard' holographic scanner into a recorder, for the purpose of yielding an output on a strip of photographic film permitting the analysis of the characteristics of wideband holograph recording, such as focusing accuracy, and tolerances. A 100 lp/mm was recorded on Type 3414 film at 33% MTF with a video bandwidth of 100 MHz and a canner speed of 52,000 rpm. (Modified author abstract)
