## Abstract A fiber Bragg grating strain sensor demodulation system based on the wavelength‐tunable fiber‐ring laser (WTFRL) is developed. The finite impulse response (FIR) digital filter and the centriod detection algorithm (CDA) are implemented to reduce the system noises and to improve the resol
