Paper Abstract

We demonstrate a high performance phase demodulator for interferometric optical fiber sensor using novel ameliorated PGC algorithm. Theoretical and experimental results show that the novel ameliorated PGC algorithm has the high stability of resist rapid change of light and low harmonic distortion advantages. Experiment results show that phase demodulator has a resolution of 2×10-5 rad / √Hz, a dynamic range of 112 dB @ 50 Hz, a linearity of better than 0.9999 and a THD of below 0.1 %.
