Spectral measurement error significance in heat and quasimonochromatic radiation radiometry

摘要

A metrological analysis of spectral measurement errors influence on the radiometric calibration errors of heat and quasimonochromatic radiation sources and radiometers is carried out.It is shown that for achievement of small radiometric measurement errors it is necessary to use high-sensivity photoelectric comparators-radiometers with constant value of spectral sensitivity in working spectral range.
