electron ptychography

Electron ptychography is an advanced imaging technique that uses an electron beam to create detailed, high-resolution images of tiny structures. It works by scanning the sample with a focused beam and collecting multiple overlapping diffraction patterns, which contain information about the sample's structure. By computationally analyzing these patterns, scientists can reconstruct a highly detailed image with resolution beyond traditional methods. This technique is valuable for examining materials at the atomic or molecular level, providing insights into their composition and properties without damaging them, and is widely used in materials science, biology, and nanotechnology.
