Abstract

Distributed Brillouin sensing Technique represents a new physical approach for temperature and strain measurements, which is based on optical time domain reflectometry (OTDR), and seems extremely promising for Structural Health Monitoring (SHM) and being received most attention. Due to the intrinsic distributed sensing capability, Brillouin can measure the temperature and strain using a single-mode fiber, which retains other typical advantages of Fiber Optic Sensors (FOS). This paper stated the current situation and prospect of distributed Brillouin sensing.
