3D Probe for Magnetic Imaging and Non-destructive Testing

Abstract : The thesis is dedicated to the development of probes based on magnetoresistive sensors capable of detecting the three components of the field simultaneously for eddy current non-destructive testing and for magnetic imaging. A first part provides an overview of the state of the art of sensors, and imaging and control methods. In a second part, the realization of the three-axis probes is given. This included the micro-fabrication, the realization of the reading electronics, the design and realization of the mechanical part and emission. For this, an important simulation work was necessary. The application of these probes to model cases for magnetic imaging with submillimeter resolution is then described. The probe proposed in this thesis has also been used successfully to detect defects in aluminum and titanium samples with a good signal-to-noise ratio.
