The Non-Destructive Evaluation (NDE) platform at Georgia Tech-CNRS IRL 2958 develops terahertz and ultrasonic approaches for the inspection and quantitative characterization of complex materials and multilayer structures. Our work combines experimental instrumentation with signal processing, inverse problems, multimodal data fusion, and machine learning to extract physically meaningful information without damaging the sample.
The platform is part of the NDE platform of the Carnot ARTS network:

It is also part of the “Optoelectronics” platform of the interdisciplinary programme MAT-PULSE, within the Initiative d’Excellence Lorraine, a France 2030 I-SITE programme.
Current activities include terahertz time-domain imaging and spectroscopy, ultrasonic inspection, stratigraphic reconstruction, sparse deconvolution, multimodal data fusion, and AI-assisted analysis.
Application areas include composites and impact damage, thin films and coatings, steel and oxide layers, microelectronics packaging, and cultural heritage.
Within the Smart Materials theme, the NDE activity is coordinated by Alexandre Locquet.
