| Abstract: | 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. |
