摘要：This article reviews author＇s research work on fiber-optic sensors over the last twenty years. It includes two aspects： low-coherence interferometric sensors （LCI） and fiber Bragg grating （FBG） sensors. For LCI sensors, author＇s work mainly focuses on the interrogation and multiplexing methods for Fizeau and Fabry-Perot interferometric sensors at the University of Kent at Canterbury （UKC）, UK, and study on novel Fabry-Perot interferometric sensors and their multiplexing methods at Chongqing University （CQU） and University of Electronic Science ＆ Technology of China （UESTC）, China, respectively. For FBG sensors, a number of multiplexing schemes are proposed and demonstrated at UKC, and then novel methods for realization of multi-parameter measurement and long-distance measurement based on the FBG sensor and its combination with other optical fiber sensors are also reported at CQU ＆ UESTC. Thus, author＇s study on these two topics can be diviaed into two periods, at UKC and at CQU ＆ UESTC, China. This review is presented in such a time sequence.
