Description
Coherent Diffraction Imaging (CDI) techniques1 under Bragg conditions are powerful tools for probing the structure of crystalline materials at the nanoscale. Traditional Bragg CDI allows for the investigation of finite crystals and enables the retrieval of structural properties under realistic environments, such as gas-phase conditions2 or electrochemical setups3,4. Bragg Ptychography (BP)5-8, by combining the principles of ptychography and Bragg CDI, leverages overlapping coherent diffraction patterns acquired at multiple scanning positions to image extended and possibly highly strained crystalline structures.
While X-ray ptychography is now a well-established method at many synchrotron facilities, Bragg Ptychography poses additional experimental and computational challenges. This talk will explore approaches to address these challenges, along with recent advances in Bragg Ptychography—including Python-based reconstruction tools, data analysis pipelines, experimental methods, and applications in materials science.
