An original monitoring (Monito-Ring) system based on chirped grating fiber optic sensor for structural strain modulation is presented. One of the main targets is to measure deformations of deformable morphing structures which may show large, global displacements. During operation, indeed, it is not often possible to connect sensors directly to the structural element because the strain which occurs is much more than the standard one can handle. Modulations are then necessary to keep the measured strain low. The proposed solution was conceived to overcome this limitation assuring a suitable reduction of the revealed strain.

Abstract

An original monitoring (Monito-Ring) system based on chirped grating fiber optic sensor for structural strain modulation is presented. One of the main targets is to measure deformations of deformable morphing structures which may show large, global displacements. During operation, indeed, it is not often possible to connect sensors directly to the structural element because the strain which occurs is much more than the standard one can handle. Modulations are then necessary to keep the measured strain low. The proposed solution was conceived to overcome this limitation assuring a suitable reduction of the revealed strain. Factors between 1 and several tenth of thousands can be achieved. This article deals with the analytical study first, and then numerical and experimental validation of the device.
