SPRING: an effective and reliable framework for image reconstruction in single-particle Coherent Diffraction Imaging

Alessandro Colombo, Mario Sauppe, Andre Al Haddad +40

Coherent Diffraction Imaging (CDI) is an experimental technique to gain images of isolated structures by recording the light scattered off the sample. In principle, the sample dens…
