Abstract
The aim of this work is to design methods and algorithms for a new fully comprehensive cloud platform, which allows to retrieve and analyse data from a set of Fibre Bragg Grating (FBG) sensors. These sensors are able to measure the displacement of a physical object caused by strain or temperature gradients. FBG technology has been widely used in many different fields, like structural health monitoring, preventive maintenance for transportation systems, monitoring of temperature and strain in rotating parts of large machines in power generation plants and more. Today FBG is a cutting-edge technology that allows to precisely measure several physical quantities, with a high reliability in environments subjected to EMI and strong electrical potentials, where the application of standard sensors may be worthless or even dangerous.
These sensors require a specific hardware gear, defined as interrogator, which uses a laser source to generate a signal that excites the FBG sensor
