<p>Disclosed are system and methods for monitoring the spectrum of at least an illumination source by at least a monitor cell with defined spectral sensitivity. The system comprises: at least a reference cell having a plurality of receivers and at least a filter adapted to provide different spectral properties to the different receivers, wherein electronic means are adapted for building at least a first output for at least a first weighted sum of the outputs of the receivers, wherein the each receiver is adapted to receive light with a certain spectral distribution.</p> |
