Uncertainty Analysis and Maintenance of the NIST Detector-based Temperature Scale

摘要：

Thermodynamic temperatures can be directly determined using the Planck radiance law and detector-based radiation thermometers. Although the fmal uncertainties in the detector-based radiation thermometry can be lower than in the ITS-90 based temperatures, detailed uncertainty analyses for each step of the detector-based realization are needed to validate these low uncertainties. We list the measurement steps in the detector-based temperatures and also describe the characterizations in determining the measurement uncertainties for each of the steps. We further describe measures to maintain the low uncertainties obtained from the radiometric calibrations.
