介绍了一种用于农业环境土壤重力水分监测的异质芯拼接光纤表面等离子体共振传感器系统。本系统在同一光纤线路上同时提供数据通信和传感功能。传感器覆盖有五氧化二钽，可以将数据传输距离延长到1310 nm波长，用于广域监测。该传感器系统可以从监测点收集远程观察到的环境数据，并将其实时发送给用户。
This paper presents a hetero-core spliced optical fiber surface plasmon resonance sensor system for soil gravity water monitoring in agricultural environments. The present system simultaneously provides data communications and sensing functions over the same optical fiber line. The sensor is covered with tantalum pentoxide, which allows data transmission distance to be extended with a wavelength of 1310 nm for wide-area monitoring. This sensor system can gather remotely observed environmental data from monitoring points and deliver them to users on a real-time basis.
