Abstract
Time-division-multiplexing(TDM) demodulation technique of Fiber Bragg Grating(FBG) sensor arrays based on a tunable pulsed laser is studied. A tunable fiber laser based on a matched FBG is applied, and the wavelengths of the sensing FBGs are obtained by determining the maximum voltages by using a photodiode. The advantages of this scheme include simple structure, high signal-to-noise ratio, and the sensing signals are obtained by determining the maximum voltages.
