A spectrally resolved scanning calibration facility based on a supercontinuum laser and monochromator (SCM) was proposed for the calibration of the absolute spectral radiance responsivity of the sensors. Two radiance meters, labeled Traps-A and Traps-B, were used herein. The absolute spectral power responsivities of the meters were traced to a cryogenic absolute radiometer. The absolute spectral radiance responsivity of Trap-B was obtained by a general unit-level calibration method, and a system-level calibration method based on the SCM with Trap-A taken as the reference. The calibration uncertainties of Traps-A and Traps-B were lower than 0.46% and 1.8%, respectively. The calibration results by the two methods were in good agreement, with a relative difference of less than 0.9% in the 450-900 nm. The results imply that a spectrally-resolved scanning calibration facility based on SCM is suitable for the absolute spectral radiometric calibration of sensors and highly applicable to the absolute spectral radiometric calibration of remote sensors.
