Enhanced Strain Measurement Sensitivity with Gold Nanoparticle-Doped Distributed Optical Fibre Sensing

Figure 1

The structure of the experimental setup. (a) The structure of the distributed fibre optic sensing system. The red dots show gold NPs randomly distributed in the core of the optical fibre. The outer layers are the cladding and coating. (b) The structure of the strain measurement system [37] with a specimen under load.
