摘要

针对多源准分布式光纤漏水传感器侧向耦合结构损耗大、精度低等问题，选用激光切割机在光纤上加工V型槽结构，提高结构的精度。选用不同激光功率与加工角度，对V型结构进行测试，通过对比传输损耗以及耦合效率，确定激光功率为20%以及加工角度为45°时具有0.2dB较低的损耗，且漏水状态下耦合结构有51%脉冲强度变化。实验结果表明，倾斜V型结构比垂直V型结构相比，传输损耗基本一致，但耦合效率以及漏水状态下脉冲强度具有明显优势，能够在漏水状态下进行有效检测。

Abstract

Aiming at the problems of high loss and low accuracy of the lateral coupling structure of the multi-source distributed optical fiber water leakage sensor

a laser cutting machine is selected to process the V-shaped groove structure on the optical fiber to improve the accuracy of the structure. Different laser powers and processing angles were selected to test the V-shaped structure. By comparing the transmission loss and coupling efficiency

it was determined that when the laser power was 20% and the processing Angle was 45°

there was a lower loss of 0.2dB

and the coupling structure had a 51% pulse intensity change in the leakage state. The experimental results show that

compared with the vertical V-shaped structure

the inclined V-shaped structure has basically the same transmission loss

but it has obvious advantages in coupling efficiency and pulse intensity in the leakage state

and can conduct effective detection in the leakage state.
