为了提高干涉微弱测量的灵敏度和分辨率，提出了一种在光路中引入长方体棱镜装置的多次反射方案，通过增加全内反射微弱值放大（WVA）系统中的反射次数，使中心波长漂移对折射率单位（RIU）的灵敏度提高了3.8倍（从1788 nm/RIU到6821 nm/RIU）。使用多次反射装置，获得了<inline-formula><tex-math notation="LaTeX">2.7 × 10$</tex-math></inline-formula>-7 RIU的RIU分辨率。实时监测多巴胺的沉积过程。
A multiple-reflection scheme was proposed to improve the sensitivity and resolution of interferometric weak measurement by introducing a cuboid prism device in the optical path. Increasing the number of reflection in a total internal reflection weak value amplification (WVA) system resulted in a 3.8 fold improvement in the sensitivity of the central wavelength shift to refractive index unit (RIU) (from 1788 nm/RIU to 6821 nm/RIU). Using the multiple reflection device, a RIU resolution of <inline-formula> <tex-math notation="LaTeX">$2.7\times 10$ </tex-math></inline-formula>-7 RIU was obtained. The real-time deposition process of dopamine is monitored.
