Two-Dimensional Far-Field Correlations of X-ray Photon Pairs
E. Strizhevsky, Y. Klein, R. Hartmann +9
We directly observe far-field correlations of x-ray photon pairs generated by spontaneous parametric down-conversion (SPDC). Using an energy-resolved, two-dimensional photon counti…

25-Fold Resolution Enhancement of X-ray Microscopy Using Multipixel Ghost Imaging
O. Sefi, A. Ben Yehuda, Y. Klein +4
Hard x-ray imaging is indispensable across diverse fields owing to its high penetrability. However, the resolution of traditional x-ray imaging modalities, such as computed tomogra…
