| 中文摘要:对基于光纤光栅测温原理的射频同轴开关内部簧片温度检测进行了研究，并使用了由聚酰亚胺涂覆的光纤光栅。温度校准后，外界温度与光纤光栅中心波长拟合直线的线性度为99.914%。温度每上升1 ℃，中心波长漂移10.39 pm。将校准后的光纤光栅置于射频开关簧片处进行测温试验。结果表明，射频开关的内部温度达到300 ℃时，光纤光栅理论上的中心波长偏移误差为0.02 nm，相应的温度重复测试误差为2 ℃。该研究为射频同轴开关内部簧片的温度检测提供了有效方法。 |

| Abstract:In this paper, the temperature detection of the reed inside RF coaxial switch based on the principle of fiber grating is studied， and the polyimide coated fiber grating is used. After the temperature calibration, the linearity of the fitting straight line using the external temperatures and the center wavelengths of the fiber grating is 99.914%. The center wavelength drift is 10.39 pm for every 1 ℃ rise. The calibrated fiber grating is placed at the reed of the RF switch for the temperature measurement experiment. The experimental results show that when the internal temperature of the RF switch reaches 300 ℃, the theoretical center wavelength deviation error of fiber grating is 0.02 nm, and the corresponding repeated temperature measurement error is 2 ℃, which provides an effective method for detecting the reed temperature inside the RF coaxial switch. |
