Contrast Enhancement of Barely Visible Impact Damage using Speckle-Based Dark-Field Radiography
Ronan Smith, Gregor Bortsnar, Vittorio Di Trapani +9
Barely visible impact damage (BVID) can cause serious issue for composite structures, due to sub-surface damage seriously reducing the strength of the material without showing easi…

Robust dark-field signal extraction for modulation-based X-ray tensor tomography
Ginevra Lautizi, Vittorio Di Trapani, Alain Studer +6
We demonstrate a robust signal extraction method for X-ray speckle-based tensor tomography. We validate the effectiveness of the method for several carbon fiber composites, highlig…
