Abstract: The present invention relates to an apparatus and to a method of optical spectrum analysis of an optical spectrum of a light beam (4), comprising the steps of selecting a certain part of the optical spectrum of the light beam (4) to provide a filtered light beam (12), detecting the filtered light beam (12) to provide an electrical signal corresponding to a power amplitude (O(λ)) of the filtered light beam (12), detecting the filtered light beam (12) to provide an electrical signal corresponding to a wavelength of the filtered light beam (12), and providing the power amplitude as a function of the wavelength of the filtered light beam (12).
