Abstract

Infrared detectors have advanced to the point where current devices are capable of achieving noise figures that are comparable to the background noise of space. Characterization tests done on these detectors at the NASA Ames Research Center have helped select the best devices for space telescopes. A highly customized system that can do these specialized tests has been developed with commercial off the shelf hardware. The data acquisition component of this system uses a pipelined architecture of multiple processors to enhance its real-time performance. This system can be customized for almost any array architecture and as more real-time performance is needed, additional processors can be incorporated. This approach permits large arrays to be tested at their maximum clocking rate.
