摘　　要：概述了干涉型光纤水听器直接调制光源的相位载波调制解调原理,对实际应用中存在的问题进行了详细的理论和模拟分析,并提出了优化调制信号幅度、消除延迟的影响以及采用自动增益控制电路来稳定光电检测输出等优化方案来提高水听器的稳定性和动态范围,减少波形畸变。The principle of phase generated carrier modulation and demodulation of intefferometric fiber-optic hydrophone with direct source modulation is described. The theoretical and simulation analysis in practical application is presented. The optimization schemes such as optimizing the amplitude of modulation signal, eliminating the influence of time delay and stabilizing the output of photo detector through automatic gain control circuitry to promote stabilization and dynamic range and reduce waveform distortion of the hydrophone are given.
