Abstract
Methods and devices for the sequential measurement of a plurality of semiconductor-based light sources that operate faster, more accurately and more sensitively than known methods and devices. In accordance with one implementation, a current pulse is applied by a pulsed current source to the low-luminosity light sources consecutively or simultaneously. The emitted light pulse of LED is converted into electric charge carriers by a photodiode, the electric charge carries are added up by means an integrator circuit, the added-together charge carriers are converted by an A/D converter into a digital signal and the digital signal is forwarded to a measurement and control unit.
