Paper Abstract

Long-wave infrared (LWIR) sensors are evaluated against the exoatmospheric background and radiometric sources of the Lockheed Sensor Test Facility (STF) cryovacuum chamber. In order to provide realistic simulations of exoatmospheric scenes, the chamber is operated at a temperature of 20 K with a pressure of 10-6 to 10-8 Corr. The chamber contains mechanically adjustable source attenuators, source positioners, and precision source scanning mirrors as well as a cold scanning spectroradiometer for in situ source calibration. These mechanisms must function in the hostile environment of the chamber without generating unwanted IR radiometric background.
