In this study, a method to improve the detection accuracy of a “weak measurement” system of optical rotation was proposed by determining the optimal total phase difference of the system. Analysis of the characteristics of weak measurement regime of the system under different total phase differences provided the total phase difference corresponding to the regime with the smallest ratio of system noise level to sensitivity (that is, the highest system resolution). In this regime, an optical rotation resolution of 5.522 × 10 ⁻⁶ ° was obtained, which is nearly an order of magnitude higher than the original system.

通过确定最佳总相位差来优化弱测量系统

在这项研究中，提出了一种通过确定系统的最佳总相位差来提高旋光度“弱测量”系统检测精度的方法。对不同总相位差下系统弱测量区的特性进行分析，得出了系统噪声电平与灵敏度之比最小（即系统分辨率最高）的区对应的总相位差。在这种情况下，获得了 5.522 × 10 ^-6 ° 的旋光分辨率 ，这比原始系统高出近一个数量级。
