Abstract

In this paper, we used Stokes-Mueller Formalism and combined a rotating wave-plate Stokes polarimeter to develop a novel polarimeter for measuring the retardance and optical rotation angle simultaneously. The average relative errors in the measured retardance and rotation angle for a half-wave plate are determined simultaneously to be just 0.40 % and 0.74 % by solving the detected Stokes parameters equations respectively. From the inspection of simultaneous measurements of retardance and rotation angle in a sample composed of a glucose solution with concentrations ranging from 0-1.2 g/dl and a posterior half-wave plate, the average relative error in the measured retardance of a half-wave plate is determined to be just 0.47 %, and the average relative error in the measured rotation angles of glucose solutions is determined to be 1.81 % under calibration with sample cell. The correlation coefficient between the measured rotation angle and the glucose concentration is found to be 0.99966, while the standard deviation is just 0.00357 degrees. Consequently, the derived algorithm for measuring the retardance and rotation angle is feasible, and the developed system has a high precision of 0.0032 % in retardance and a good precision of approximately 10 % in rotation angle measurements.
