Abstract

We have developed a method to design and calibrate the high-precision variable polarization light source (VPOLS) with an accuracy better than 0.0013. According to the design model, a novel technique for the calibration of the VPOLS based on the autocollimator and the optical auxiliary apparatus was presented and discussed; moreover, the degree of linear polarization (DOLP) comparison tests of the VPOLS compared with Spectro-polarimetric Analyzer (SPOLA) have been carried out. Experimental results show good consistency between the numerical calculated DOLP values of the VPOLS and the measured values of the SPOLA.
