Abstract

Optical fiber sensors bring to measurement systems all the advantages inherent to the optical fibers technology. In this frame, fiber Bragg gratings (FBGs) are particularly interesting, thanks to their wavelength-encoded response and inherent multiplexing capability. As many FBGs can be interrogated using a single device, the cost per sensor unit can be drastically decreased, above all when an efficient and cost-effective interrogation set-up is developed. Such a development constitutes the main objective pursued in the work presented here.
