Spectroscopic Mueller matrix polarimeter by two liquid crystal polarization modulator

All polarization characteristics can be described by Mueller matrix. We propose a measurement method for the Mueller matrix measured by two polarization modulators of liquid crystal set with 45° and 0° of azimuthal direction. We succeed to measure spectroscopic Mueller matrix without any mechanical unit after retardations of two liquid crystal modulators by are calibrated spectroscopic Stokes polarimeter.
