A polarization measuring device is operated by passing light having a predetermined input polarization state to a sample for a potentially polarization changing interaction and from the sample through a polarization selective analyzer and to an intensity detector. The method proceeds by varying an angle between the output polarization state of the light emanating from the sample and the analyzer. The wavelength of the light reaching the intensity detector is varied, and a plurality of intensity measurements are performed successively at different constellations of polarization. Spectral modulation states and corresponding intensity values are stored together with polarization and spectral values representing the corresponding constellation. The polarization modulation and the spectral modulation are performed simultaneously and continuously, and during a single, monotonic variation of the polarization modulation state, the spectral modulation state is varied plural times and during each spectral modulation period (τ) plural successive intensity measurements are performed.
