| 针对光纤光栅温度传感器管式封装时，高温下环境聚合物粘接材料性能不稳定的问题，提出一种无胶封装方法，选用石英套管作为封装材料，利用高频CO2激光脉冲加热，使传输光纤与石英套管实现可靠焊接，并对封装后的传感器的温度特性进行测试，实验结果表明，石英套管封装的光纤光栅温度传感器在室温~300℃具有很好的线性，可实现对环境温度的测量。 |
| 英文摘要: |
| In order to solve the problem of unstable performance of polymer bonding material in high temperature environment when fiber Bragg grating temperature sensor is encapsulated in tube, a non-adhesive encapsulation method is proposed. Quartz sleeve is selected as encapsulation material and heated by high frequency CO2 laser pulse. The transmission fiber and quartz sleeve can be reliably welded and the encapsulated sensor can be used. The temperature characteristics of the device are tested. The experimental results show that the fiber grating temperature sensor encapsulated by quartz sleeve has a good linearity between room temperature to 300 C, and can be used to measure the ambient temperature. |
