121. Thermodynamic Radiation Thermometry for the Next SI
Howard W Yoon, Charles E Gibson, V B Khromchenko, George P Eppeldauer, Robert R. Bousquet, Steven W Brown, Keith R Lykke
We describe the construction, the calibration and the use of the NIST Thermodynamic Radiation Thermometer (TRT) to measure the temperature of the gold-freezing temperature blackbody and a variable-temperature blackbody from 800 ?C to 2700 ?C. These ...
122. Thermodynamic-Temperature Determinations of the Ag and Au Freezing Temperatures Using a Detector-Based Radiation Thermometer
Howard W Yoon, David W Allen, Charles E Gibson, Maritoni Abatayo Litorja, Robert D. Saunders, Steven W Brown, George P Eppeldauer, Keith R Lykke
We describe the development of a radiation thermometer calibrated for spectral radiance responsivity using cryogenic, electrical-substitution radiometry to determine the thermodynamic temperatures of the Ag- and Au-freezing temperatures. The absolut ...
123. Uncertainties of Spectral Responsivity Measurements
George P Eppeldauer, G Sauter, James Gardner
Uncertainty estimates of detector spectral responsivity measurements are discussed. A model describes independent (uncorrelated) uncertainty components at a given wavelength based on the measurement equation for test detector calibrations. Systematic ...
