【摘要】 为了对Sagnac干涉型水听器的信号进行解调,在讨论了Sagnac干涉型水听器的原理,得到和Mach-Zehnder干涉型水听器的不同之处后,提出了相应的解调技术.并用软件实现了信号的解调.解调结果表明,输出信号与输出信号完全一致,并可以准确标定出干涉仪的相位调制.更多还原

【Abstract】 To demodulate the signals generating from fiber optical Sagnac interferometric hydrophone, the principle of the interferometer and the difference with Mach-Zehnder interferometric hydrophone are studied. The related demodulation technique is developed and realized by software. The results show the output signals are the same as input signals, and the phase modulation can be marked precisely.更多还原
