A Novel Distributed Spun Fiber Twist Sensor Based on Frequency-Scanning φ-OTDR (W2B.7)
Presenter: Can Chen, Huazhong University of Science and Techn
A novel distributed twist sensor utilizing frequency-scanning φ-OTDR in a spun fiber is theoretically analyzed and experimentally demonstrated by tracking the fiber twist induced frequency shift of correlation peak, enabling distributed quantitative twist measurement.
