改进了一种用于物光琼斯矢量成像的离轴数字全息光学系统，并构造了一种新的参考光法拉第旋光器。为了评估偏振分析的准确性，四分之一和半波片被用作对象，透射光的偏振态的分布进行了分析，为各种取向的波片。偏振分析也进行了模拟，和消光比和参考波的调制误差的有限值的效果进行了数值研究。
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.
