Paper Abstract

A new interrogation scheme for civil engineering transducers is presented. Although it was developed in the first place for Fiber Bragg Grating based transducers, it has also demonstrated a good performance when interrogating other type of sensors such as those based on Low Finesse Fabry-Pérot Cavities. The proposed unit is able to extract the required information from the transducers by measuring the characteristics of the near field radiation created in the surroundings of a tilted fiber Bragg grating. This working principle makes it very attractive and suitable for civil engineering structural monitoring. Among the technical characteristics of the scheme, the following should be highlighted: inherent capability for extracting information of wavelength multiplexed FBG-based transducers, very wide wavelength operation range, and good wavelength resolution.
