Fibre Optic Sensors and Interrogators
Despite their excellent characteristics, the diffusion of current commercial fibre optic sensors (FOS) is limited by their high costs. This activity is aimed at widening their usage by investigating the potentiality of new sensors based on plastic optical fibres (POF) and studying innovative interrogation techniques for glass-based FOS, such as Fibre Bragg Gratings (FBG).
Typical applications include both physical (e.g. strains, temperature) and chemical/biochemical quantities. One of the first results has been the realization of a low cost crack monitoring system (dubbed LOCK), installed and tested in a prestigious monument in Venice. About ten international patents have been filed as results of this activity. Part of this activity is carried out in cooperation with the Electronics Measurement group and part with the Istituto Superiore Mario Boella.
