Abstract: The demodulation method of FBG (fiber Bragg grating) is the key technology of fiber grating sensors.The model of fiber grating demodulation system, which is based on single-chip, has been proposed in this article.The principle of fiber grating sensor and the frame of the demodulation system have also been researched.It has been proved the measure precision of the system arrives at 5 pm, the demodulation system is universal and lower cost, and it is the key to the practicality of Bragg grating sensors.

Keywords: Bragg grating; Fabry-Perot demodulation; Single-chip
