| Abstract: | A circumflexion sensor based on fiber Bragg grating is presented and experimentally studied.The sensing principle is theoretically analyzed,and the sensor is successfully used to measure the variation of circumflexion.The experiment results indicate that the sensor has good linear response capacity.A dual-gratings method is used to eliminate the cross-sensitivity due to the temperature. |
| Keywords: | Fiber Bragg grating Circumflexion sensor Cross sensitivity |
