摘要

摘要提出了一种基于金属焊接技术的光纤法布里-珀罗（F-P）温度传感器。光纤传感器由单模光纤和金属毛细管组成，采用金属焊接技术封装。从理论上分析了空腔长度与灵敏度之间的关系。实验结果表明，该传感器的灵敏度达到3.85 纳米 / ° C，当F-P腔长度为171时 μm。此外，F-P温度传感器的灵敏度随着F-P温度传感腔长度的减小而增加。所提出的采用金属焊接技术制造的传感器具有灵敏度高、制造简单、结构简单、成本低的优点。

Optical fiber Fabry-Perot temperature sensor based on metal welding technology

Abstract. We present an optical fiber Fabry-Perot (F-P) temperature sensor based on metal welding technology. The fiber sensor is composed of a single-mode fiber and a metal capillary that are encapsulated by metal welding technology. The relationship between the cavity length and sensitivity is analyzed theoretically. The experimental results show that the sensitivity of the fabricated sensor reaches 3.85 nm / ° C when the F-P cavity length is 171 μm. In addition, the sensitivity of the F-P temperature sensor increases as the cavity length of the F-P temperature sensor decreases. The proposed sensor fabricated by metal welding technology has the advantages of a high sensitivity, simple fabrication, simple structure, and low cost.
