Title: NIST Technical Note No. 1621: Optical radiation measurements based on detector standards
Published: March 11, 2009
Abstract: Improved detector technology in the past two decades opened a new era in the field of optical radiation measurements. Lower calibration and measurement uncertainties can be achieved with modern detector/radiometer standards than traditionally used source (blackbody and lamp) standards. The achievable lower uncertainties gave the motivation to decrease the gap between the 0.02 % (k=2) relative expanded uncertainty of cryogenic radiometer measurements and the 2-3 orders of magnitude higher uncertainties of field level optical radiation measurements.
