摘要

提出了一种同时测量旋转角和椭圆度的激光偏振信号测量实验。由于用于构建复合偏振测量装置的偏振元件的消光比有限，该实验不受信噪比下降的影响。噪声分析表明，在同时测量偏振角和椭圆度时，所提出的方案可以达到量子噪声的极限。这项工作应该对真空磁双折射观察、自旋轨道相互作用、材料表征、偏振显微镜或生物医学光学等实验有很大的兴趣。

Simultaneous measurement of polarization rotation angle and ellipticity at the quantum noise limit

An experiment has been proposed for laser polarization signal measurement, with the rotation angle and ellipticity being measured simultaneously. The proposed experiment is immune to signal-to-noise ratio degradation due to the finite extinction ratio of polarizing elements used to construct the composite polarization measurement setup. Noise analysis is carried out to show that the proposed scheme allows one to reach the quantum noise limit in the simultaneous measurement of the polarization angle and ellipticity. This work should be of great interest for experiments such as observation of vacuum magnetic birefringence, spin-orbital interaction, material characterization, polarization microscopy, or biomedical optics.
