摘要
本文分析氯化钻溶液热色效应的特点,利用这一效应设计了一种医用光纤温度传感器,由实验数据分析钻盐溶液配比变化对传感器输出的影响.
At a wave length around 660 nm, there occurs strong optical absorption by a CoCl2 solution with a change in temperature. An optical fiber is used to transmit light through the solution. The variation of output light intensity from the fiber will indicate the temperature variation. An optical fiber temperature sensor can thus be constructed. Experiments show that there exist good formulations of the solution that will give better sensitivity and linearity of the sensor as well as a resolution of 0.1℃. The temperature sensor in question is mainly used in the field of biomedical researches.
