Abstract
32 x 32 and 64 x 64 staring infrared focal plane arrays with epitaxial HgCdTe and InAsSb photovoltaic detectors coupled to surface channel CCD multiplexers have been fabri-cated and characterized. The backside-illuminated detector arrays have bandgaps suitable for operation in either the 3-5 or 8-12 μm region. A source-coupled input circuit with background suppression is utilized. Performance characterization of the multiplexer will be given at cryogenic temperatures. CCD charge transfer efficiency and MOSFET threshold voltages have been measured as functions of temperature. The input circuit 1/f noise will be characterized. The detectivity and noise equivalent temperature of the hybrid focal planes will also be discussed.© (1981) COPYRIGHT SPIE--The International Society for Optical Engineering.
