| Abstract: | An improved phase generated carrier(PGC) demodulation method based on optical fiber interferometer sensors was brought forward.Through improvement on the PGC algorithm and adding frequency overlapped-resistable filter to the system,the result of the demodulation system has been great improved.At the same time,the sample rate of the system has get great reduced.The conclusion is very useful in designing the demodulation systems based on optical fiber interferometer sensors. |
