ptychography

Ptychography is a sophisticated imaging technique used to reveal fine details of an object's structure. It combines overlapping snapshots of light patterns, which are produced when coherent light, like X-rays or lasers, hits a sample. By analyzing these patterns and how they change as the light moves, researchers can reconstruct a high-resolution image of the sample without needing traditional lenses. This method is particularly valuable for studying materials at the nanoscale, in fields like materials science and biology, allowing scientists to see intricate features that are otherwise invisible with standard imaging techniques.
