Reconstruction of Defect Paths Using Eddy Current Testing Array 3D Imaging
In a world where the reliability and lifespan of industrial equipment are critical, our research aims to go beyond the traditional limits of non-destructive testing. We seek to achieve accurate detection and comprehensive imaging of defects in their various forms by harnessing the capabilities of eddy current testing with multiplexing technology on multi-element sensors. This approach allows us to save time and ensure the quality of results. This paper presents a method for detecting and imaging different defect paths on an aluminium plate. Our methodology involves the strategic deployment of multi-sensor techniques specifically designed for eddy current testing. To address the inherent challenge of mutual magnetic induction between these sensors, we employ the alternating feed method, which is an advanced technology that ensures data integrity and significantly accelerates scanning times. By combining this technology with multi-sensor techniques, we capture signals that provide valuable insights into the presence of defects. Additionally, we produce 3D imaging that enables us to trace their paths, regardless of size. These preliminary results lay the foundation for future research aimed at accurately characterizing and visualizing the shapes and dimensions of these defects, thereby contributing to a more comprehensive understanding of defect behaviour.

Inspection of aluminum sheets using a multi-element eddy current sensor: 2d and 3d imaging of surface defects of various sizes and internal defects at various depths
In the industrial sector, ensuring reliability and durability is of paramount importance. Our research aims to advance beyond conventional non-destructive testing methods by focusing on thorough defect detection and imaging. We utilize advanced, sensor-enhanced eddy current testing, featuring multiple elements arranged in a cutting-edge serial array. This innovative configuration addresses the issue of magnetic repulsion between sensor elements, thereby speeding up the testing process and ensuring precise results through both 3D and 2D imaging. This sophisticated approach allows us to more effectively characterize defects of varying sizes and depths in aluminum sheets. By meticulously collecting and analyzing data from the sensors, we can identify the appearance and nature of these defects with greater clarity. Our findings introduce a pioneering method for defect detection, highlighting the efficacy of our advanced testing technique. Our research underscores the potential of multi-element eddy current sensors in revolutionizing the inspection process. The ability to produce detailed 3D and 2D images of surface and internal defects represents a significant leap forward in non-destructive testing. This comprehensive imaging capability not only accelerates the detection process but also enhances the accuracy and reliability of defect characterization. By employing this state-of-the-art technology, we can detect even the smallest and most deeply embedded defects that traditional methods might miss. The precise imaging provided by our approach ensures that defects of various sizes and depths are accurately identified and characterized. This level of detail is crucial for maintaining the structural integrity and performance of aluminum sheets used in industrial applications. Our research demonstrates a groundbreaking approach to defect detection in aluminum sheets, leveraging the advanced capabilities of multi-element eddy current sensors. The innovative use of a serial array of sensors, combined with sophisticated data analysis techniques, allows for rapid, accurate, and detailed imaging of defects. These findings pave the way for improved reliability and durability in industrial applications, setting a new standard for non-destructive testing.

Non-destructive rapid defect testing around curved head rivets without displacement of eddy current sensors
In the field of aeronautics, it is essential to ensure the structural integrity of aircraft components. Non-destructive testing (NDT) plays a crucial role in ensuring the safety and reliability of structures used in aeronautics as it enables the detection of defects and imperfections without damaging the inspected parts. Domed head rivets are commonly used in aeronautics to assemble multilayer structures due to their strength and ability to maintain the structural integrity of aircraft. However, inspecting these assembly areas can be challenging and presents unique challenges in terms of non-destructive testing due to the curved surface of the rivet, resulting in lift-off variation during surface scanning and a modification of the trajectory of eddy currents near the rivet. This can lead to changes in the response of eddy currents, complicating the accurate interpretation of test results. In recent years, researchers have focused on developing advanced eddy current testing methods to detect defects in complex structures, such as those found in aeronautics. In this work, we propose a promising solution to address both the shape of the rivet and the probe displacement issue during testing. We have developed a model based on the finite element method (FEM) using COMSOL Multiphysics for non-destructive testing through 3D imaging using a matrix of multiplexed multi-element eddy current sensors distributed over multiple layers around the rivet without the need for the displacement of this matrix and capable of adapting to the variation in the diameter of the domed head rivet. The non-displacement of the sensors eliminates parasitic signals that can lead to errors in the interpretation of obtained signals, and the multiplexed powering of the sensors eliminates the mutual inductance effect between adjacent coils.

Non Destructive Testing for a Multilayer Structure used in Aeronautics by Eddy Current Multi-Sensor System
The goal of non-destructive testing (NDT) is to determine a part's integrity without causing damage to it. Early diagnosis of a fault in high-risk fields like nuclear or aeronautics can save lives and save significant material and human losses. In the field of non-destructive testing (NDT), eddy current imaging technology is based on multi-element sensors consisting of numerous eddy current probes eddy current probes positioned side by side for data collecting. The assembly of the is possible thanks to multiplexing, which avoids mutual inductance between the individual probes. The ICFMM is designed for non-destructive evaluation of flaws in the area of rivets on aeronautical and other structures, and will allow defect characterisation using 3D pictures that represent impedance variation.

3D Imaging by Eddy Currents From Multi-Element Sensors in Multiplexed Mode Applied to Multilayer Structures Used in Aeronautics
The Eddy Current (EC) technique is widely used in the field of non-destructive testing of electrically conductive materials. It is easy to implement and robust in industrial applications, but it is relatively costly when large surfaces of parts to inspect are involved. New reliable and quick testing systems are emerging such as eddy current imaging systems which have recently been developed to produce EC images with good defect characterisation performance. It is obtained by mechanical scanning procedures of a set of individual coils, grouped in a single probe and forming the multi-element coil system. The use of a multi element sensor system makes it possible to control a large surface area and thus reduce the number of particularly time-consuming scans, and to minimise the effect of mutuality between adjacent coils, a multiplexed supply of the elements making up the multi-element sensor is carried out. It is in this context that our work "3D Eddy Current Imaging from Multi-element Sensors in Multiplexed Mode Applied to Multilayer Structures Used in Aeronautics" is situated.
