Abstract

The Infrared Instrumentation System (IRIS) is an operational infrared imaging radiometer developed and operated by Automated Sciences Group, Inc. under contracts DASG60-89-C- 0055 and DASG60-92-C-0111 to the U.S. Army Space and Strategic Defense Command in Huntsville, AL. The IRIS operates in calibrated bandpasses from 1.3 to 14 micrometers using three IR staring focal plane arrays and from 0.4 to 0.9 micrometers using an intensified visible camera. The IRIS is located on its own independent pointing and tracking platform on the High Altitude Observatory (HALO), a Gulfstream IIB operated under contact to the U.S. Army by another company. The IRIS has a high-speed digital data recording system for the three IR sensors and an analog video recording capability for all four sensors. This paper discusses the modular design and operational flexibility of the IRIS. A discussion of the theoretical performance predictions and actual sensitivities as measured in the laboratory and from stellar calibrations is included.
