本文对以Mach-Zehnder干涉仪结构的单模光纤声传感器及其外差检测进行了理论分析和实验研究,成功地实现了具有相位反馈的外差系统(HPFI),实验结果与文献[6]的基本一致。
In this paper, theoretical analysis and experimental research on the single-mode optical fiber acoustic sensor with Mach-Zehnder interferometer and its heterodyne detection are carried out. The heterodyne system with phase feedback (HPFI) has been successfully realized. The experimental results are in good agreement with the literature [6] Basically the same.
