Abstract

Ball Aerospace & Technologies Corp. (BATC) has added a powerful capability to its existing imaging spectrometer alignment and test facilities: Scanning Fabry-Perot source filters. These interferometers provide a means for efficient instrument testing with full characterization from the ultra-violet (UV) to longwave infrared (LWIR). Spectral Response Functions (SRF) and geometric distortions are accurately determined with a common approach. The techniques were demonstrated with a two band cryogenic LWIR spectrometer and with the mid-wave infrared (MWIR) Spaceborne InfraRed Atmospheric Sounder for Geosynchronous Earth Orbit (SIRAS-G) laboratory demonstration imaging spectrometer. The spectrometer testing and performance is presented.
