摘要

This paper describes a new configuration of the channeled spectropolarimeter and its application for the spectroscopic measurement of Mueller matrix, The new configuration uses the channeled spectroscopic polarization state generator (CSPSG) consisting of a polarizer and two high-order retarders, The channeled spectropolaiime-ter using the CSPSG has features that up to four independent polarimetric parameters about a sample can be determined simultaneously from a single channeled spectrum and that it is almost immune to the wavefront perturbations induced by the sample.To apply the channeled spectropolarimetry for the full measurement of Mueller matrix, the CSPSG is combined with a rotating compensator spectropolarimeter,. All elements of the spectroscopic Mueller matrix are determined from four channeled spectra. Its feature is that it requires only one rotating component for the full Mueller matrix measurement.
