Figure 3 shows a sheet-type optical-fiber sensor. The optical fiber was wound and fixed using polyimide films.
Figure 5 shows a comparison of the waveforms and their frequency spectra detected by the sheet-type sensor and the directly wound optical-fiber sensor (fiber width: 6 mm) on the surface of a pipe.
The gradual success of
optical-fiber sensors is attributed to their application in tackling difficult measurement situations where conventional sensors do not provide the required accuracy.
The team looked to
optical-fiber sensors, which are one of the best sensor technologies for use in harsh environments thanks to their extraordinary multiplexing capabilities and immunity to electromagnetic interference.
Polarimetric optical-fiber sensors embedded in composite laminates can monitor structural integrity and detect damage while the structure remains in service.
Optical-fiber sensors have shown a potential to serve this purpose.
