Optical fiber sensing technology
Optical fiber sensor is a passive sensor that uses optical cable as information transmission medium, such as Sensing medium, which can sense environmental changes such as strain, temperature, refractive index, liquid level, sound wave, air pressure and vibration near the optical cable.
Structural health monitoring
It can be understood as the integration of sensing and intelligence to enable the structure loading and damage-provoking conditions to be recorded, analyzed, localized, and predicted. OFS provides integrated, quasi-distributed, or fully distributed technologies that are suitable for SHM fields.
