Fiber Bragg Grating Current Sensor
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.
