摘要

The new common-path circular polariscope and the Senarmont setup with electro-optic modulation for measuring the optical linear birefringent media properties are presented. It enables the measurement of not only the phase retardation but also the principal axis angle. The measurement procedure is carried out in two setups. In the first one, we use the electro-optic modulated circular heterodyne interferometer and the phase-lock technique to precisely measure the principal axis angle. After removing the first quarter-wave plate in the first setup, a Senarmont setup is designed to determine the phase retardation also using the phase-lock technique. The simple phase extraction algorithm for the principal axis angle and the phase retardation measurement is presented. The root-mean-square resolutions for the principal axis angle and phase retardation are found to be 0.0247° and 0.0304°, respectively, with corresponding dynamic ranges of 0-180° and 0-90°.
