一种双通道光纤光栅温度检测系统的研究

摘要

光纤光栅以其独特的优点,在温度测量中得到了越来越广泛的应用.在用分布式光纤光栅阵列进行测温时,由于受到传感光栅之间的缓冲区和探测范围的限制,使得测温点数有限.文章提出了基于光强的双通道分布式光纤光栅温度检测系统,在未改变缓冲区和探测范围的前提下,扩展了测温点数.%Optical fiber grating with its unique advantages, has been used more and more widely in the temperature measurement. When we use distributed optical fiber grating arrays to measure temperature, the grating due to a buffer between the sensors and the detection scope, makes the temperature measurement points limited, In this paper, based on the light intensity of dual-channel optical fiber grating distributed temperature detection system, under the premise without changes in the scope of the buffer zone and detection, is proposed to expand the temperature measurement points.
