The objective of this thesis is to design one of the first mixed real-time visualization frameworks for Fibre Bragg Grating (FBG) sensors, and it is an improvement of a previously developed framework created as a general open source tool for any FBG-based IoT system. Its integration is justified by the lack of mixed real-time monitoring tools for those sensors in literature. The project was developed in collaboration with the DAUIN, DIMEAS and DISAT department of Politecnico di Torino, as part of the Inter-Departmental Center for Photonic technologies (PhotoNext). The framework is divided into two different applications developed with Unity3D engine, one for desktop system and another one for the Microsoft Hololens headset.
