| Zusammenfassung | The spectral characterisation of detectors is mostly done with lamp and monochromator-based facilities such as the spectrally tuneable "light" sources. The measurement uncertainty of this approach is mainly determined by the limited optical power and wavelength offsets of the spectrally filtered lamp radiation [1]. Due to the rapid progress in laser technology, such setups can nowadays be replaced by tuneable laser facilities. The advantages of tuneable laser radiation are much higher output power levels combined with simultaneously narrow bandwidth. Both are essential for the measurement of steep spectral response functions with the lowest uncertainties. This paper gives an overview on the current status of the laser-based characterisation of detectors, cameras and spectroradiometers, as well as on the first results of exclusively detector-based calibrations of light sources, carried out at PTB. |
