Paper Abstract

This report proposes an optical rotation measurement using Stokes parameters with a dual rotating retarder and analyzer. The intensity captured by a spectrometer is modulated by a retarder and an analyzer in a rotating ratio of one to three. The Stokes parameters and retardance along the wavelength of the retarder are simultaneously analyzed by Fourier transform. Two standard quartz plates of 0.8 mm and 1.6 mm thickness are measured for a sample. The characteristics of optical rotation dispersion of the two standard quartz plates correspond with theoretical values at wavelengths from 550 nm to 900 nm. We succeeded to separate the optical rotation from the birefringence.
