Abstract

In order to improve the all kind of fiber Bragg grating (FBG) demodulation system, we make-up a fiber grating temperature demodulation system, which is consist of fiber tunable F-P filter, signal-generation, tunable voltage source and oscilloscope. The temperature signal of three FBG with different center wavelength is demodulated, and the system is demonstrated to be with sensing sensitivity of 10.47mV/°C, 10.16 mV/°C, 10.48 mV/°C. The structure of the system is very simple and easy to be realized.
