The article presents information on coherent X-ray diffraction imaging (CXDI), a technique used for studying objects at the nanoscale level. CXDI is a lensless imaging technique that involves measuring the coherent X-ray diffraction pattern of a sample and then using a mathematical phase-retrieval method to obtain a real-space image. CXDI involves the use of a phase retrieval algorithm used to reconstruct images from the diffraction data.
