| 摘 要： | 半导体吸收式光纤温度传感器因其具有电绝缘性好、抗电磁干扰、无火花、能在易燃易爆的环境下使用等优点而越来越受到重视。通过分析它的工作原理和系统结构，针对确定的光源、半导体薄片、探测器等元件，建立了完整的系统模型，并对模型进行Ymatlab仿真分析，得出各元件对系统输出的影响规律和参数选取原则；搭建了实验平台并进了实验，得到系统输出曲线。结果表明系统在263K-419K的温度范围内有1K的测量精确度和0．1K的分辨力，以及良好的线性度和反应时间。结合实验中的出现的问题对系统的实用化存在的困难以及可能的解决方案进行了分析。

| Abstract: | The fiber optic temperature sensor based on semiconductor optical-absorption has many advantages over conventional ones, so it is especially suitable to be used in strong electromagnetic, combustible, narrow, and explosive spaces. Through analyzing its operating principles and system structure, the mathematical model of the system is established, which is composed of specific semiconductor chip, light source, detector, and optical fiber. By analyzing the model with matlab, the law of used components on syst... |
