摘要
An overview of fiber laser sensing is presented.The design and the characteristics of distributed feedback(DFB)fiber lasers for high performance sensing applications are described.Demodulation techniques based on unbalanced fiber interferometer are discussed,especially for the noise level,the dynamic range,and the crosstalk in dense-wavelength-division multiplexing.Finally,the fiber laser sensing system configurations and field demonstrations for different applications are illustrated.
