%X The Phase Generator Carrier(PGC)method in fiber interferometer was proposed and investigated.The digitized PGC demodulation was mathematically deduced,calculated and emulated.The key technology digital low pass filter is analyzed detailedly,the reason why the filter influence the performance of the PGC demodulation and the design method of the filter is presented.The influence of the sensor light power to the output of the PGC demodulation is discussed.The modification of the PGC demodulation algorithm is i...
