Fiber optic sensing technology has been widely applied in civil engineering.
In this field, fiber optic sensing is primarily used for the monitoring of large structures,
the safety performance of roads/railways and bridges, as well as the detection of
deformation and internal forces in concrete structures.
Fiber optic sensors are lightweight and can be directly attached to ceilings, branches,
and cave walls for measurements from various angles.
In civil engineering, the data required is usually very precise, and fiber optic sensors
meet this requirement effectively.
Tests on fiber optic sensors yield higher accuracy, providing more detailed and accurate
data for the construction and maintenance of civil engineering projects.
The principle of the distributed fiber optic sensing system involves using the fiber optic
itself as both the sensing element and the signal transmission medium.
This system employs advanced OTDR technology to detect changes in temperature and
strain at different points along the fiber, achieving true distributed measurement
