摘要：
Optical fiber gas sensors have giant application prospects in mine, oilfield and industrial production due to the advantages of intrinsic safety, less environmental impact and remote measurement. The modification with functional nano materials has led to more research ideas for optical fiber sensing in the field of gas detection. The optical fiber gas sensors are classified based on the operating principle. The advantages and current applications of optical fiber gas sensors are briefly introduced. Then, the basic principles and key technologies of four types of sensing optical fiber gas sensors are introduced in detail. The optical fiber structure of the sensing optical fiber gas sensors can be changed by micro-processing means such as polish-grinding, corroding, tapering, etc. and supplemented by the modification of special nano-materials, then the ultra-high precision refractive index measurement can be achieved, which provides a new method with low detection limit, high sensitivity and specificity for optical fiber gas detection technology. Finally, the existing problems and future development directions of optical fiber gas sensors modified by nano-materials are summarized. © 2020, Science Press. All right reserved.
