Abstract:

Coherent X-ray Diffraction Imaging (CXDI) is a technique for the 2-dimensional (2D) and 3D reconstruction of nanoscale structures. The detector receives the photons scattered by the object, and ideally, the diffraction pattern gives the power spectrum of the electron density. Since we are only provided the power spectrum and the phase is lost, we need to retrieve the phase in order to reconstruct the structure from the diffraction image.
