Distributed fiber-optic temperature and strain measurement with extremely high spatial resolution
Sampling of the Rayleigh scattering along a length of optical fiber allows the realization of a distributed sensor system where every point along the fiber acts as a sensor. This novel method allows ...
Continuous fiber optic strain measurement
Some bridges in Germany are aging and not designed for today’s increasing traffic loads. Authorities must now find cost-effective solutions to manage these existing structures.
Distributed Fiber-Optic Sensing for Geotechnical Monitoring
Stones, blocks, steel, cement, concrete, and mortar—combined with large, heavy, clumsy, and noisy construction machinery—hardly make an ideal environment for a fragile glass fiber.
Fiber Bragg Grating Sensors in Practice
Fiber-optic sensors are used in wind turbines not only for monitoring but also for control, for example, to adjust the rotor blades based on load measurements of the blades.
How fiber-optic temperature measurement helps develop Power-to-X technologies for the energy transition
Fiber-optic systems measure temperatures across fields, excelling where many sensors, compact size, and low thermal mass are needed—one 150 µm fiber can replace hundreds of sensors.
Fiber-Optic Temperature Measurement in Chemical Process Engineering
Conventional measurement methods quickly reach their limits when electromagnetic immunity, high measurement density, or chemically aggressive environments are required
Fiber-optic sensing in basic research
Friction clutches are used in millions of automobiles to transfer the engine’s torque to the drivetrain. However, the physical processes involved in frictional power transmission are still not completely u…
