| Research Abstract |
This project aimed to improve the basic performance and enhance the functions of the channeled spectropolarimetry. We found two causes of the systematic errors, the transmittance instability of the polarizer for the calibration and the polarization imperfection of the sensing head. By eliminating the effects of the error causes, the accuracies of 0.1deg in the polarization measurement were obtained. The wavelength resolution of the spectroscopic polarization measurement was enhanced by introducing the dispersion compensated sensing head. The incorporation of the wavelength scanning laser enables us to apply the channeled spectropolarimetry for the Mueller matrix measurement and the two-dimensional measurement of polarimetric samples.
