Optical Activity Measurements by Interferometry-Diffraction Technique: Test with BSO Crystals

Abstract

To measure the optical rotation of a material, we propose a technique which we couple Mach-Zehnder interferometer and an optical Fourier processor 2F. The method uses the dependence of the contrast of the interference fringes with the angle between the planes of polarization of the two beams of the interferometer. The technique allows following the dynamic variations of optical activity, directly observing the changes in the intensity of the diffraction orders in the exit plane of the Fourier processor 2F. We present results.
