| 摘 要： | 介绍一种基于稀土荧光材料（Y^2O^2S:Eu)温度－荧光特性的光纤荧光温度传感器，由紫外汞灯发出的紫外光补调制成脉冲激励光，通过光纤传输激发探头处的荧光材料产生荧光，通过测量两个峰值荧光信号的值得到输出与温度的关系，温度测量误差小于0．5℃。实验结果表明，文具该测系统能够有效地消除光源不稳定及测量通道中光强度化对测量 结果的影响。

| Abstract: | A fluorescence temperature sensor with optical fiber based on the characteristic of temperature-fluorescence of rare earth phosphor is described.The ultraviolet light from ultraviolet Hg lamp is modulated to pulsed light,exciting phosphor in probe to emit fluorescence through optical fiber.The relation between output and temperature is obtained by measuring the ratio of two peak fluorescence signal,making the measurement of temperatures to 0.5℃ precision.The experimental results show that this temperature measuring system can effectively decrease the influence of instability of light source and intensity variation in measuring channel on measurement results. |
