Classification of optical fiber temperature sensor

Time:2023-12-18 Views:249
光纤温度传感器是利用某些物质吸收的光谱随温度变化的原理,对光纤传输的光谱进行分析,以了解实时温度的传感设备。
主要分为以下几类:
1.相位调制光纤温度传感器,如Mach-Zehnder-mz干涉仪、fp-Fabry-Perot干涉仪、光纤光栅温度传感器和幅度调制型,如微弯损耗调制偏振调制型等。LCD温度测量
2.热辐射光纤温度传感器利用光纤中产生的热辐射来感测温度,这是基于光纤芯中热点产生的黑体辐射现象。蓝宝石光纤温度传感器
3.一种光传输光纤温度传感器,其使用光纤作为用于传输测量信号的传感器。敏感部件不是光纤。如半导体光吸收传感器、荧光光纤温度传感器、热变色光纤温度传感器等。
