Résumé :	Non Destructive Testing plays an essential role in safety, quality and the reliability of industrial systems. In this thesis, two eddy current sensors designed form several coils that are placed in array form to characterize fiber orientation and for detecting in-plane fiber waviness in unidirectional CFRP. The principles of the proposed sensors are based on those of conventional rotating sensors. Our proposals allow the elimination of mechanical rotation, which offers advantages of speed of inspection, precision and miniaturization. The first sensor is based on the absolute mode; however the second uses the transmission-reception mode. To benefit at the same time from the advantages of the interactive arrayed sensor and the receiving arrayed sensor, we have proposed a synthesis of these two sensors in a single device. This gives a possibility to use a single sensor that functions both as an interactive arrayed sensor and as a receiving arrayed sensor. We are used the 3D finite elements method in 'Comsol multiphysics' environment to study the electromagnetic phenomena. To validate the results obtained by simulation, experimental measurements were carried-out in the case of two coils sensor.
