Abstract:
An Acoustic Charge Transport Imager, suitable for use as a High Definition Television (HDTV) camera element, is disclosed in which an array of amorphous hydrogenated silicon based avalanche photodiodes are combined with acoustic charge transport channels in a GaAs substrate, to achieve very high speed read out of photogenerated charge. High speed read out allows the fabrication of detector arrays large enough to meet the resolution requirements of HDTV while ensuring operation within the timing constraints of the HDTV frame rate.
