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…
