摘要

采用多模干涉光纤作为折射率传感器，开发了高精度的多点传感测量技术。他们使用了一种精细的校准技术，使用波长选择光学滤波器和来自可调谐激光源的定义波长光。在多点传感条件下，平均RI分辨率为4.3 ×10−6 RIU。

Multipoint Sensing System with a Fine Refractive Index Resolution by Combining Multimode-Interference-Sensors and Wavelength Selection Configuration

Multipoint sensing measurement with fine resolution was developed using multimode interference optical fibers, working as refractive index (RI) sensors. They were operated with a fine calibration technique using a wavelength selective optical filter and defined-wavelength-light from a tunable laser source. Average RI resolution is 4.3 ×10−6 RIU under multipoint sensing conditions.
