X-ray ptychography is a synchrotron-based imaging technique that produces sub-micrometer quantitative maps of a transmission function through the combination of diffraction measurements from the illumination of multiple overlapping regions on the specimen. Thanks to the information gain provided by the diversity of the measurements, image reconstruction from ptychographic data is especially robust in comparison to other X-ray lensless imaging methods. The technique has been extended to three-dimensional imaging and is now used routinely at a few dedicated instruments. This talk will give an overview of recent developments in the field, from biomedical applications to extensions of the method for partial coherence, dynamical studies, and near-field imaging.
