Abstract: Fiber Bragg Grating Demodulation System is the key to put Bragg Grating
sensor into practice. The fiber grating sensor theory and the demodulation
technology is systematically researched in this paper. The main content includes:
the principle of fiber grating sensor; the analysis of several technologies of
demodulation and the F-P filter demodulation is introduced in detail; the design
of demodulation system based on MCS system. Fiber Bragg Grating calibrating method base
on MCS can improve precision of Demodulation System equal to ±5pm, maximum error
±8pm.
