Single-Shot Hybrid CP- φOTDR/CP-BOTDA System for Simultaneous Distributed Temperature/Strain Sensing (Th2A.15)
Presenter: Yuan Wang, University of Ottawa
A real-time simultaneous temperature and strain measurement based on hybrid chirped pulsed φ-OTDR and BOTDA is demonstrated for the first time. The high accuracy of 4.3 µε for strain and 0.32°C for temperature is achieved over 5 km non-uniform fiber.
