Abstract: 基于悬臂梁技术 ,分析并验证了光纤光栅用于电流传感的可能性。采用等腰三角形悬臂梁确保光栅在传感过程中不出现啁啾现象 ,从而减小读数误差。系统传感灵敏度为 4 0 0× 10 - 2 nm A ,与预期值 4 15× 10 - 2 nm A基本吻合。
The performance of fiber Bragg grating glued on a cantilever beam used for current sensing is analyzed and demonstrated. The isosceles triangle shaped beam makes the grating chirp free and, hence, reduces the reading error. The measured sensing sensitivity is 4.00×10 -2 nm/A which is close to the predicted value of 4.15×10 -2 nm/A.
