This paper is aimed at describing the realization of an electronic system for interrogation of fiber optic strain sensors for several application fields. One of the most important industrial sector where fiber sensors are becoming more popular is the aerospace industry, where the main applications are oriented to the strain monitoring inside metal or composite structures. These analyses are aimed mainly at obtaining higher safety level, higher structural reliability and lower maintenance and operative costs of aerospace structures. In particular, FBG sensors can be employed in the nondestructive control sector applications as structural test, structural health monitoring and loads monitoring. The work is centered on fiber optic Bragg grating (FBG) sensors, due to the possibility to detect strains in specific points of complex structures getting useful information for design and stress analysis. This application is of particular …
