摘要
对当前荧光式光纤测温的研究热点,提出一种适合于嵌入式系统和现场使用的高精度温度测量方法——Prony法的荧光寿命式光纤测温。从荧光式光纤测温机理出发,分析Prony法双指数模型测量机理,提出温度测量系统具体方案。基于测试数据和使用效果,给出温度与荧光寿命的标定与验证方法。据此设计出的温度产品具有良好的性能价格比,已经在实际中获得成功应用。
Aim at the hotspot of temperature measure base on optical fiber of fluorescence lifetime.the paper offered the Prony algorithm.It is a high-accuracy method of temperature measure.On the basis of mechanization of temperature measure,the paper expatiate double exponential function mathematical model base on Prony algorithm and the specific scheme of temperature measurement system is confirmed.Built in a large quantity of testing data and application effect,a calibration and validation measure for temperature and fluorescence lifetime is Given.The method have optimum performance-cost ratio.The temperature device based on this mean had been successfully applied to actual fields.
