摘要：
A novel fiber Bragg grating (FBG) sensor system for static and dynamic measurements with a wavelength-swept fiber laser is proposed and demonstrated. In this system, both static and dynamic perturbation of each FBG in the sensor arrays can be interrogated simultaneously. The experiments demonstrated the strain resolutions of similar to 1 mu epsilon and 3.4 n epsilon/root Hz at 500 Hz for static and dynamic measurements, respectively.
