摘　　要：在介绍短周期光纤光栅(FBG)和微纳光纤布拉格光栅(MNFBG)折射率传感原理的基础上,围绕如何提高FBG折射率传感灵敏度,详细论述了腐蚀法和抛磨法两种折射率传感技术方案的研究进展,对比分析了两种方案的优缺点。同时综述了微纳光纤和微纳光纤光栅应用于折射率传感的研究现状,指出了目前研究所面临的技术难题与解决方案,展望了FBG折射率传感技术的发展趋势,可为进一步开展基于光纤光栅器件的折射率传感研究提供参考。Based on the introduction of sensing principles of short-period fiber Bragg grating （FBG） and mi- cro-nano fiber Bragg grating （MNFBG） refractive index and how to improve FBG refractive index sensing sensitivity, the research progress of two refractive index sensing technology schemes such as etching and polishing methods are described in detail. The advantages and disadvantages of the two schemes are compared and analyzed. The research status of micro-nano fiber and fiber grating used in refractive index sensing is summarized. The technology prob- lems and solution schemes on current research are proposed and the development trend of FBG refractive index sensing technology is forecasted, which provide a reference for further research on refractive index sensing based on fiber grating devices.
