Abstract
To shorten the long calibration chain when using the conventional source-based approach and therefore to reduce spectroradiometer's calibration uncertainty, we developed a detector-based approach to calibrate spectroradiometers directly against a transfer trap detector using a tunable laser. Two different detector-based methods are used for the calibration and their calibration results are in very good agreement with each other. The calibration result is also compared with that obtained using a working standard FEL lamp and the agreement is within the expanded uncertainties (k=2) of the working standard FEL lamp. This detector-based approach enables new, independent realizations of spectral irradiance or radiance scales on spectroradiometers. Such spectroradiometers can be used as instrument-based primary or transfer standards to disseminate spectral irradiance or radiance scale with a smaller uncertainty.Proceedings Title
