To address the issues of not accurately identifying ice types and thickness in current fiber-optic ice sensors, in this paper, we design a novel fiber-optic ice sensor based on the reflected light intensity modulation method and total reflection principle. The performance of the fiber-optic ice sensor was simulated by ray tracing. The low-temperature icing tests validated the performance of the fiber-optic ice sensor. It is shown that the ice sensor can detect different ice types and the thickness from 0.5 to 5 mm at temperatures of -5 °C, -20 °C, and -40 °C. The maximum measurement error is 0.283 mm. The proposed ice sensor provides promising applications in aircraft and wind turbine icing detection.
为了解决当前光纤冰传感器在识别冰类型和厚度方面不够准确的问题，本文设计了一种基于反射光强度调制法和全反射原理的新型光纤冰传感器。通过光线追踪对光纤冰传感器的性能进行了模拟，低温结冰测试验证了光纤冰传感器的性能。结果表明，该冰传感器可以在-5°C、-20°C 和-40°C 的温度下检测到不同类型和厚度为 0.5 至 5 毫米的冰。最大测量误差为 0.283 毫米。所提出的冰传感器在飞机和风力涡轮机结冰检测方面具有广阔的应用前景。
