A polarimeter based on Stokes-Mueller formalism and rotating-wave-plate Stokes polarimeter is successfully developed to measure the optical rotation angle in a chiral medium. The average relative error in the measured rotation angles of glucose solutions with concentrations ranging from 0 to 1.2g/dl is determined to be 3.78%. The correlation coefficient between the measured rotation angle and the glucose concentration is found to be 0.9995, while the standard deviation is just 0.00376 degrees. From the sol-gel materials containing C 17 H 17 ClO 6 with concentrations ranging from 0 to 0.0665g/ml, the average relative error in the measured rotation angles is determined to be 3.63%. Consequently, the developed system is evaluated with a precision of 5.4% approximately in rotation angle measurement. IntroductionsIn 1997, Cameron and Cóte [1] designed a glucose sensing digital closed-loop processing system, which is based on the heterodyne interference technique and a lock-in amplifier is used to obtain the rotation angle of the glucose. MethodAccording to the Stokes-Mueller formalism, the Stokes vector S models the polarization state of incident light and the Mueller matrix for a chiral medium is expressed as CB M , hence, the Stokes vector CB S of output light is calculated by a

Consequently, the derived algorithm for measuring the optical rotation angle of a chiral medium is feasible.
