An optical system of off-axis digital holography for imaging the Jones vector of an object wave is improved, and a Faraday rotator for the reference wave is also newly constructed. To evaluate the accuracy of the polarization analysis, quarter- and half-wave plates are used as the object, and the distribution of the polarization state of the transmitted light is analyzed for various orientations of the wave plates. The polarization analysis is also simulated, and the effect of a finite value of the extinction ratio and the modulation error for the reference wave is investigated numerically.
