Ptychography imaging of the phase vortices in the x-ray beam formed by nanofocusing lenses

D. Dzhigaev, U. Lorenz, R. Kurta +11

We present the ptychography reconstruction of the x-ray beam formed by nanofocusing lenses (NFLs) containing a number of phase singularities (vortices) in the vicinity of the focal…
