Review on the development of fiber laser sensor structures
Fiber laser sensing technology is an important part of fiber sensing technology.Firstly,the principle of fiber laser sens-ing technology is introduced,then the principle and characteristics of ten kinds of fiber laser sensors based on single structure and double structure are analyzed,and the application and temperature sensitivity of two kinds of sensor structures are compared.Fi-nally,the fiber laser sensing technology is summarized and prospected from three aspects,such as demodulation mode,multi-pa-rameter measurement and improved detection range.
