The Realization of PGC Scheme Interferometric Fiber-optic Sensor
This paper presents the research on the interferometric fiber-optic sensor's PGC scheme which is suitable for the construction of the acoustic sensor array. The new bandwidth requirement of the scheme is analyzed, and high sensitivity fiber-optic acoustic sensor detected by PGC scheme is successfully developed with LD and its frequency modulating technique. The stabilized acoustic signal is obtained by the sensor in the state's first class acoustic measurement station.
