Résumé en anglais

Terahertz technology (between 0.1 and 4 THz) is now a well-established tool to achieve contact- free and non-destructive testing (NDT). Among the technologies, THz CT and phase retrieval are emerging techniques which have been investigated during the last decade. Thus, in this presentation, we focus on the analyze capabilities from 3D reconstructed volumes of a complex object obtained by a real time-THz imaging system. We demonstrate that images obtained are compatible with an automated processing composed of: i) an ad-hoc segmentation, extracting the sample from the background and reconstruction noise ii) a component labelling, iii) a skeletonization, providing additional meta-data about the sample morphology. We also present how we can assess to phase information of the object by phase retrieval from intensity measured in a volumetric grid.< Réduire
