摘　　要：提出了一种荧光光纤温度测量系统.采用双光路双通道测量方式以及化学镀膜和热处理工艺相结合的微小荧光探头制作技术,在研究微弱信号的检测和处理技术的基础上,选用小波变换技术对荧光信号进行消噪处理.系统的温度实验、标定实验和重复性实验.结果表明该系统具有较高的准确度和温度分辨能力.The fluorescence fiber temperature measurement system was proposed. Using the double light paths and double channels measurement, the micro fluorescence probe was made by the chemical conversion coating technique and heat treatment process combination. The wavelet transform was used to eliminate the noise in the fluorescence signal. The results show that this system has higher precision and resolution by the temperature experiment, the verification experimental and the repetitive experiment.
