<title>Calibration Support Of The AN/AAM-60 Common Forward-Looking Infrared (FLIR) Test Bench</title>

Abstract

The AN/AAM-60 Common FLIR Test Bench includes an infrared target source to provide a test pattern for forward looking infrared (FLIR) systems used on Navy aircraft. To ensure that the Common FLIR Test Bench properly tests the FLIR system, it was necessary to establish radiometric calibration support for the infrared target source. Accordingly, a calibration hierarchy has been established that links the contrast of the infrared target source test patterns to radiometric standards at the National Bureau of Standards. A transportable calibration system has been developed for use by on-site teams in mapping the test pattern with a radiometer. Horizontal lines are scanned by means of a special purpose test fixture utilizing a motor drive on the radiometer mount at selected elevations. The radiometer output is displayed as a function of position on a strip chart recorder corresponding to the scan across the target. The radiometer is calibrated in terms of the temperature of special purpose ambient range blackbody standards at Navy calibration, laboratories. The blackbodies are calibrated by the Navy Primary Standards Department against a master blackbody directly traceable to the National Bureau of Standards.© (1982) COPYRIGHT SPIE--The International Society for Optical Engineering.
