Abstract :
We report a high-speed long distance FBG sensor interrogation using 1.3 μm FDML wavelength-swept laser. The static strain and dynamic strain response for long distance FBG interrogation system is achieved. The FDML laser could be operated if the scanning frequency of the Fabry-Perot tunable-filter matches with the fundamental frequency of the laser cavity.
