The radiometric errors introduced by the optical components of a high-performance imaging infrared radiometer have been quantified both theoretically and experimentally. The excellent agreement obtained has enabled an algorithm to be implemented within the system processing electronics to 'correct' the apparent temperature of the displayed internal temperature references for such radiometric errors. Corrections have been evaluated both for the scanner unit with a wide angle window and with an optional x20 telescope. The radiometer under discussion is the Dual Waveband Imaging Radiometer which has proved to be a very successful data collection tool due to its unique combination of a high performnance imager offering simultaneous 3-5 micron and 8-12 micron TV compatible outputs together with internal temperature references to provide real-time temperature calibration. The prototype has been used extensively for IR signature collection.
