摘要
空芯光纤已经成功用于红外波段的传能与气体传感。利用金属膜空芯光纤在可见光波段的低损耗特性,进行有色溶液测量。基于可见光光谱吸收法,设计并搭建了稳定实用的溶液浓度传感系统。从理论上对系统进行仿真计算,分析了系统的传感特性。实验测定了氯化钴溶液的浓度,结果表明系统具有响应速度快、操作便捷和灵敏度高的优点。另外,系统具有可小型化及可在线检测的特点,在环境监测、化工过程监控和医药生产等领域都有广阔的应用前景。
Abstract
Hollow fiber has been successfully used in infrared wavelength regions for energy delivery and gas sensing. Metallic hollow fiber is used in spectroscopic sensing system for colored solutions owing to its low-loss property in visible light regions. A stable and practical sensing system is established for detecting the concentration of colored solutions based on spectroscopic absorption. The system sensing characterizations are analysed by theoretical analysis and computational simulation. Experiments on measuring the concentration of CoCl2 water solution are conducted. The experimental results show that the system has the advantages of rapid response, easy operation and high sensitivity. The possibilities of miniaturization and on-line measurement make the system a potential candidate for promising applications in the environment monitoring, chemical process control and medicine fabrication processing etc.
