A TUM/Diamond/KTH/UCL team demonstrates speckle based x-ray phase contrast, applied to material characterization, using a MetalJet x-ray source from Excillum. The method is based on correlation of near-field speckles and yields quantitative measurements of the full X-ray refractive index of the object with high sensitivity. X-ray speckle tracking tomography broadens the capabilities of X-ray imaging at laboratory sources with strong potential in materials and life sciences.
