The usage of LEDs for lighting purposes introduced new challenges in photometry. Additionally, new demands in detector based radiometry, due to the launch of detectors like for example hyperspectral imagers, extended the requirements for measurement techniques and capabilities. Current measurement methods are based on lamp/monochromator setups or continuous-wave (cw) or pulsed lasers. These methods either provide a large tunable wavelength range or irradiance with a small bandpass. Furthermore, the usability is limited, the uncertainty for low responsivity detectors is high, and interference effects can occur if no diffuser is used. In this thesis the SRPL (Spectral Responsivity with Pulsed Lasers) method is presented comprising a measureme...
