摘要
概述了Mach -Zehnder干涉型光纤水听器两种不同的调制解调技术 ,着重分析了用 3× 3耦合器组成的干涉型光纤水听器的解调原理。比较分析了这两种方案的特点 ,指出采用 3×
The demodulation principle of fiber optic hydrophone is described. A 3×3 coupler based demodulator for fiber optic hydrophones is introduced,followed by analysis and comparison of two different kinds of demodulation technique. It is pointed out that the 3×3 coupler demodulation technique is a preferred approach for making up all fiber interferometric hydrophones and hydrophone arrays for the future.
