Abstract
A pyroelectric detector was calibrated against the National Institute of Standards and Technology (NIST) High Accuracy Cryogenic Radiometer (HACR) at 10.6 um using a CO2 laser as a source. The purpose of this calibration was to link the NIST infrared (IR) radiometric detector scales to the HACR. Issues addressed in this calibration included the spatial non-uniformity of the pyroelectric detector, the transport and alignment of the IR laser beam, and the measurement of ac signals. The final combined relative standard uncertainty of the calibration is 0.48% with the largest uncertainty component arising from the spatial non-uniformity of the pyroelectric detector. The apparatus, measurement procedures, and results of the calibration will be discussed.Citation
