【Abstract】 In this paper, Both Single-Mode Optical Fiber Acoustic Sensor with Mach-Zehnder Interferometer structure and Heterodyne Detection Technology are studied theoretically and experimentally. The Heterodyne system with Phase Feedback Interferometer (HPFI) is realized successfully. The experimental results agree well with those obtained abroad.更多还原
