| 英文摘要 | A method of detecting the phase congruency of distributed feedback(DFB) optical fiber laser hydrophones was proposed based on detection system of traditional piezoelectric hydrophones, and the phase congruency detection system was set up. A polarization-insensitive unbalanced Michelson fiber interferometer was employed to transfer the frequency shifts to the phase shifts of the interferometer. After converting the output optical signal of the interferometer to electric signal, a normalized phase generated carrier(PGC) demodulation technique was used to demodulate the acoustic signal. Then the demodulated signal and the signal of the reference piezoelectric hydrophone were input into a high-resolution digital phase detector to get the phase difference. Repeat the above steps with another optical fiber laser hydrophone and compare the two results, the phase congruency between the two optical fiber laser hydrophones would be calculated. Corresponding experiments show the reliability of the phase congruency detection system and the high phase congruency between optical fiber laser hydrophones. |
