摘要
通过严密的数学推导,对直接调制光源产生相位载波的马赫-曾德尔(Mach-Zehnder)干涉型光纤水听器调制解调技术进行了研究。在这一思想的指导下完成了相位载波(PGC)检测电路的硬件设计,给出了实验结果。
The phase modulation and demodulation of interferometric Mach-Zehnder fiber-optic hydrophone using phase generated carrier (PGC) technique with direct laser source modulation is analyzed through rigorous mathematical calculation. Following this idea, the hardware design of PGC detection system is completed and the experimental results are given out.
