Fiber Bragg grating (FBG) sensors are often used as sensing elements for displacement measurements, because they are resistant to electromagnetic interference, corrosion, on top of that, they are compact and they have high sensitivity.
FBG displacement sensors, unlike strain and temperature, can’t measure quantity using only fiber optic sensors; it utilizes FBG response to its equivalent Bragg wavelength. Displacement sensor measures structural deformation estimation using the strain data. Sensor is installed on the structure surface and measures the distance between two anchor points. It can be used in a combination with additional components to determine soil displacement. It can be used to monitor extension and compression displacement. Fiber optic displacement sensors are widely used to measure the gaps in bridges, buildings, roads, dams and other constructions. Fiber Bragg displacement sensors are more durable and provide long-term safety compared to traditional sensors.
