The present invention relates to a system and method for measuring a wavelength-resolved state of polarization, for calculating differential group delay of an optical signal under analysis () by means of taking multiple measurements of the spectrum of the signal under analysis () with spectral filtering means () with an optical output the power of which depends on the polarization of the input. The polarization at the input of the spectral filtering means () is modified by means of a polarization transformer () which sequentially selects a plurality of output states of polarization. The spectral filtering means () can comprise a filter based on stimulated Brillouin scattering amplification () simultaneously combining wavelength discrimination and polarization discrimination.
