Abstract:
1. A system for measuring the state of polarization (SOP) of wavelength components in a multi-wavelength input light beam, comprising: a set of two or more rapidly switchable waveplates selectively controllable to receive and operate on the input light beam to form a sequence of secondary light beams with different polarizations; a polarizer oriented to pass a select polarization and arranged to receive the secondary light beams and form a corresponding first sequence of polarization-filtered light beams; a first spectral dispersing element arranged to spatially disperse the wavelengths components of one of the input light beam, the secondary light beams and the polarization-filtered light beams; and a first detector array arranged to receive and detect the spatially dispersed wavelength components of each of the polarization-filtered light beams.
