刻纹光纤温度敏感特性的理论与实验研究

Theory and Experiment of Temperature Sensitivity of Etched Optical Fiber Sensor

理论分析与实验研究揭示环境温度变化对刻纹光纤中传输的光功率影响极小（其δＰ／ＰδＴ为１０－６／℃量级），表明刻纹光纤不适于直接用于温度传感测量，在应力、应变等传感测量中也可忽视温度的影响。

It has been shown by theoretical analysis and experiment that the change of optical power transmitting in an etched optical fiber induced by the variation of environmental temperature is very small (δ P/P δ T is about 10 -6 /℃). It indicates that the etched optical fiber cannot be directly used to temperature sensing measurement, and the effect of temperature in strain, or stress sensing measurement can be also neglected.
