ABSTRACT

A novel fiber sensor based on photonic crystal fiber (PCF) for simultaneous measurement of temperature and humidity is proposed. The PCF is filled with alcohol, which is sensitive to temperature. And it is coated with graphene oxide (GO), which is sensitive to humidity. In the range of 10°C–70°C, the highest temperature sensitivity of the three interference valleys can reach up to 0.182 nm/°C. Similarly, in the range of 30%–70%, the highest humidity sensitivity is 0.109 nm/%RH. This configuration features the advantages of reliable repeatability, strong stability, and it is ideal for environmental detection.

基于酒精填充光子晶体光纤的传感器的重复性和稳定性研究

摘要

提出了一种基于光子晶体光纤（PCF）的新型光纤传感器，用于同时测量温度和湿度。PCF充满对温度敏感的酒精。并涂有对湿度敏感的氧化石墨烯（GO）。在10°C–70°C的范围内，三个干扰谷的最高温度灵敏度可以达到0.182 nm /°C。同样，在30％–70％的范围内，最高湿度灵敏度为0.109 nm /％RH。该配置具有可重复性可靠，稳定性强的优点，是环境检测的理想选择。
