SPIE - Education Infrared Radiometric Calibration SC1109

This course describes the radiometric calibration techniques used for SI-traceable measurements of sources, detectors and material properties in the infrared wavelength region. The main goal is to enable understanding of infrared measurements with quantified uncertainties so that full uncertainty budgets can be established for the final quantities. Examples from NIST calibrations of sources, detectors and materials will be described. The properties and measurements of various different blackbody and lamp sources will be discussed. Detector calibrations using both thermal and quantum detectors with monochromators and Fourier-transform spectrometers will be covered. Also, infrared reflectance measurements using Fourier-transform spectrometers will be explained. Examples of NIST-developed infrared transfer and working standard radiometers in field deployments will be utilized to illustrate the above concepts.
