摘　　要：为解决马赫-泽德光纤干涉仪在实际应用中遇到的噪声、扰动等的影响,介绍了采用高双折射的偏振保持光纤做成的单根光纤干涉型压力传感器的检测原理,光传输特性、信号处理方法和结果.特别指出了光纤压力传感器的一些技术要点.In order to solve the influence caused by the noise and interference problems in practical applications of the Mach-Zehnder optical fibre interferometer, the single optical fibre, interferometric-type pressure transducer which is composed of the polarization-preserved optical fibre with high dual-refraction feature is introduced. The detecting principle, transmission features and the signal processing method of the transducer are presented. Some technical keypoints of the optical fibre transducer are described emphatically.

关 键 词：光纤压力传感器 压力传感器 偏振保持光纤
