Design of PGC Demodulation Circuit Using for Sagnac Interferometer
In this article,PGC arithmetic at length was discussed and then the hardware system basing on PGC technology was designed.The system has been applied for a new pipeline leakage detection system based on Sagnac interferometer to demodulate interference signal phase.It is proved that the circuit can demodulate leakage signal effectively,and leaking point is located accurately.
