The PhotoNext project consists in retrieving and processing information coming from a set of Fiber Bragg Grating (FBG) sensors, so that its status can be visualized in a simple and immediate way through a heat-mapped 3D model. It is carried out in collaboration with the Department of Control and Computer Engineering (DAUIN) and the Department of Mechanical and Aerospace Engineering (DIMEAS) of the Politecnico di Torino, as a part of the Inter-Departmental Centerfor Photonic technologies. The entire architecture is primarily developed to analyze and monitor a model aircraft created by the Icarus team in Politecnico di Torino. FBG sensors are devices that exploits photosensitivity: they measure the variation of the refractive index of the optical fiber core caused by some physical effect such as strain, pressure and temperature.
