一、前言与常规传感器相比,光导纤维传感系统具有许多明显的优点,如它们丝毫不受射频场和其它电磁辐射的干扰且绝缘性能极佳。又因为它们不会产生电流和电火花,所以可在各种危险的环境中使用,且由于材料成本低廉,因此还可用其作为工作环境温度的探测器。随着接 I. Introduction Compared with conventional sensors, optical fiber sensing systems have many obvious advantages, such as their freedom from radio frequency fields and other electromagnetic interference and excellent insulation properties. And since they do not generate current and sparks they can be used in a variety of hazardous environments and because of their low material costs they can also be used as detectors for working ambient temperatures. With the answer
