Paper Abstract

All polarization characteristics can be described by Mueller matrix. These polarized parameters are captured by changing the states of polarization given by combination of polarization generator and polarization analyzer. We employ double liquid crystal phase modulators whose orientation is set 45 degrees by changing the rubbing direction of orientation film. A unit of LC phase modulators is set in temperature-controlled environment and calibrated spectroscopic Stokes polarimeter. A measurement method for obtaining Mueller matrix is to applied that the phase of LC phase modulators are changed with the phase modulation in the proportion of one part to five. We succeed to measure spectroscopic Mueller matrix without any mechanical movement with high accuracy.
