Ptychography is a high-resolution imaging technique which does not require lenses for image magnification and which provides phase contrast with high sensitivity. Here we propose to use x-ray ptychography for the imaging of surface structure in crystalline samples. We show that ptychography can be used to image atomic structures using coherent diffraction patterns recorded along the crystal truncation rod of a crystal surface. In a proof-of-concept experiment on a Pt(111) sample, we present ptychographic reconstructions showing features consistent with surface steps. Furthermore, due to the penetration power of x-rays, this method could find interesting applications for the study of surface structures under buried interfaces or in harsh environments.
