Paper Abstract

In this paper we describe the construction of an infrared imaging camera system utilizing a linear 32-element InSb array developed by Cincinnati Electronics (CE) and the Jet Propulsion Laboratory (JPL). This camera system was designed for astronomical infrared imaging in the J, H, K, L, and M bands, primarily at the Cerro Tololo Interamerican Observatory (CTIO)* in Chile. Previously published reports 1,2,3,4,5,6 indicated that this array had the desirable characteristics required for astronomical applications, such as high quantum efficiency, low dark current with lower temperature operation, and large well capacity. The only drawback was the relatively high noise resulting from the high video line capacitance. In fact, the noise has proven to be the most difficult system problem because low-background operation necessitates integration times sufficient to insure that source flux noise becomes the limiting factor.
