Continued Development of Indium Antimonide CID Arrays.
Abstract
Two-dimensional 16x24 InSb CID area arrays have been designed and successfully fabricated via a multilayer MIS processing technique. The operation of these arrays in a staring mode has been demonstrated by displaying real time raster-scanned IR images on an X-Y CRT monitor. The raw video image displays were as sharp as the actual objects, being clearly recognizable with no sign of blooming and, therefore, excellent operating characteristic. Theoretical analysis showed that at low sample rates, a background limited performance (BLIP) can be obtained at background photon flux levels of as low as mid-10 to the 12th power photons/sec-sq cm. The dominant noise source, in this case, is the integrated dark current shot noise. For operation at high sample rates, however, the bandwidth-dependent noise sources limit the array performance and, thus, BLIP occurs at higher background levels. The analysis has been confirmed by measured data on line arrays, resulting in good agreement between the theoretical curve and the experimental data. (Author)
