中文摘要 | we present a novel reference compensation method for eliminating environmental noise in interferometric wavelength shift demodulation for dynamic fiber bragg grating (fbg) sensors. by employing a shielded wavelength-division-multiplexed reference fbg in the system the environmental noise is mea, sured from the reference channel, and then subtracted from the demodulation result of each sensor channel. an approximate 40 db reduction of the environmental noise has been experimentally achieved over a frequency range from 20 hz to 2 khz. this method is also suitable for the elimination of broadband environmental noise. the corresponding fbg sensor array system proposed in this paper has shown a wave-length resolution of 7 x 10(-4) pm/root hz.
