The above is but a modest list that shows the use of optical
fibre technology. As can be seen from the list, various optical fibre
structures (such as single mode, multi-mode, photonic crystal fibre
etc.) and techniques (i.e. fibre gratings, SPR – surface plasmon
resonance) can be utilised to tailor-make sensors for various applications.
One of the most used phenomena for fibre sensing is
the photosensitivity in optical fibres
