| Abstract: | Fiber-optic hydrophone is a subaqueous sound sensor which is built on optical fiber and optoelectronics. By high sensitivity fiber-optic interferential measurement, a water sound signal is converted to aoptic signal, and sent to the signal processing system to pick-up the sound signal information. The phase generated carrier in signal demodulation of fiber-optic interferential hydrophone is studied and the subaqueous sound detection is conducted using mixed A/D PGC demodulation mode. |
