摘要：

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 2.7 x 10-7 RIU was obtained. The real-time deposition process of dopamine is monitored.
