摘要
介绍了分布式光纤Sagnac定位传感器的工作原理,分析了国内外研究中的单Sagnac环形、双Sa-gnac环形、Sagnac-Michelson和Sagnac-Mach-Zehnder形等各种结构形式,以及位置信息的解调方法,讨论了该类型的传感器的优点及需要改进之处。
The principle of the distributed fiber-optic Sagnac location sensor is introduced. The structures studied at home and abroad such as single-loop Sagnac, two-loop Sagnac, merged Sagnac-Michelso and Sagnac intefferometere hybrid Mach-Zehnder are analyzed,as well as location signal demodulation algorithm. The merits and drawbacks which need to be improved of fiber-optic distributed Sagnac location sensor are discussed.
