摘要
利用半导体光吸收原理,设计了一种可在高压、强电磁干扰环境下应用的温度传感器,系统引入了参考光源和光纤通信用组件,大大减少了光源强度变化及光纤连接损耗对传感器的影响,提高了系统的探测距离和稳定性。
A novel design for fiber-optical temperature sensor based on the property of semiconductor band edge absorption used under adverse conditions. The influence of light source intensity fluctuation, and the coupling and connecting loss in the fibers can be greatly reduced and the stability of the system can be improved due to the introduction of the reference light source and some subassemblies of optical communications.
