摘要
为了实现太空环境下的卫星折反射星敏器光学系统中特殊结构部位的传感器的安装及温度监测, 排除应变对传感器的影响, 设计了一种适用于光纤光栅的环形特殊封装结构。并对传感器进行了温度标定、拉伸、温度重复性、振动及热真空实验。实验结果表明:这种封装形式的光纤光栅温度传感器线性度为0.998, 温度灵敏度为8.5~8.7pm/℃, 同一温度下, 中心波长变化量在2pm以内, 同时, 该结构形变产生的应变对传感器中心波长没有影响; 在振动及热真空环境下, 传感器的性能不会受到影响。
Abstract
In order to realize sensor installation and temperature measurement and monitoring of the special structural parts in the optic system of satellite catadioptric star sensor in the outer space environment, and remove the effects of strain on the sensor, an annular special packaging structure for fiber Bragg grating was designed. And the experiments on temperature calibration, tensile experiment, temperature repeatability, vibration and thermal vacuum were carried out. Experimental results show that the linearity of this packaged fiber Bragg grating temperature sensor is 0.998, and the temperature sensitivity is 8.5~8.7pm/℃. Under the same temperature, the center wavelength variation is within 2pm, and the strain of structural deformation has no effect on the center wavelength of the sensor. In the vibration and thermal vacuum environment, the performance of the sensor will not be affected.
