Doherty A, Buchanan I, Roche I Morgo O, Astolfo A, Savvidis S, Gerli M, et al.
Optica . 2024 Dec; 11(12):1603-1613. PMID: 39735734
X-ray dark-field imaging highlights sample structures through contrast generated by sub-resolution features within the inspected volume. Quantifying dark-field signals generally involves multiple exposures for phase retrieval, separating contributions from scattering,...
