| 摘 要： | 本文介绍了一种探针型光纤传感器。其结构简单、灵敏度高。保偏光纤中两正交偏振模受外场作用,其传播速度发生变化,形成相位差。根据这一特性,该传感器能检测压力、温度、电场、磁场等物理量。

| Abstract: | This paper presents a probe-shaped optical fiber sensor with a simple construction and a high sensitivity. The propagation velocities of the two orthogonally polarised modes in a "polarisation-maintaining" fiber are changed when exposed to external fields resulting in phase difference. According to this feature, this sensor can be used to measure the pressure, temperature and electro-magnetism field etc. |
