摘要
这篇文章考察我察觉到的新光纤维(OFS ) 在重庆大学和中国的电子科技的大学在中国研究活动最后十年,自从我在 1999 从英国回来了。在长时期纤维栅栏(LPFG ) 的研究进步,分布式的纤维察觉到系统和 microfiber 传感器被介绍。为 LPFG,有 LPFG 的高周波的 CO2 激光脉搏类型的处理方法制作了,为光察觉到和光通讯的相关应用被描述。为察觉到系统的分布式的纤维,光纤的极化光时间领域反射计(POTDR ) ,光纤的阶段敏感的光时间领域反射计(-OTDR) 和 Brillouin 光时间域分析器(BOTDA ) 分别地被开发。为 microfiber 传感器,我们主要为折射索引和加速察觉到集中于结共鸣器和它的应用程序,等等。
This article reviews my new optical fiber sensing (OFS) research activities in China for the last ten years at Chongqing University and University of Electronic Science and Technology of China, since I returned from UK in 1999. The research progress in long period fiber gratings (LPFGs), distributed fiber sensing systems and microfiber sensors is introduced. For LPFGs, the processing method with high-frequency CO2 laser pulses types of LPFGs fabricated and the related applications for both optical sensing and optical communication are described. For distributed fiber sensing systems, the fiber-optic polarization optical time domain reflectometer (POTDR), fiber-optic phase-sensitive optical time domain reflectometer (φ-OTDR) and Brillouin optical time-domain analyzer (BOTDA) are developed, respectively. For microfiber sensors, we mainly focus on the knot resonator and its application for sensing of the refractive index and acceleration, etc.
