摘要
在高功率微波(HPM)辐照下,吸波材料会有明显的升温效应。利用光纤布拉格光栅(FBG)对某蜂窝吸波材料表面的温度变化进行了多点实时监测,得到了该材料在HPM辐照下表面温度的变化特性。这种测试方法可以进一步推广到强电磁环境下材料的其它参数的实时监测中。
The fiber Bragg grating (FBG) has many unique advantages, such as small size, light weight, flexibility, immunity to the radiation, and especially suitable for the application in strong electromagnetic environment. Radiated by high power microwave (HPM) , the temperature of wave-absorbing materials will rise significantly. The FBG is applied to monitor the muhipoint temperatures on the surface of one piece of microwave absorbing material, which is radiated by I-IPM. This technology can also be extended to other real-time monitoring in the strong electromagnetic environment.
