Analysis of Crosstalk in Fiber Grating Sensor Array Caused by Fiber-End Reflection
Signal crosstalk of the fiber grating array induced by fiber-end reflection is calculated and analyzed theoretically. The signal crosstalk value of the sensor array element caused by the end reflection is tested by experiment. According to the mechanism of the signal crosstalk, the suppression method of the fiber-end reflection is proposed, and it is verified by experiment. After suppression of the fiber-end reflection, the crosstalk value is less than -70 dB due to the fiber-end reflection, which can meet the requirement of actual use of the fiber grating sensor array.
