Electron Tomography

This lecture covers the principles and applications of 3D Microscopy and Tomography, including techniques such as Atom Probe Tomography, Field Emission Microscopy, and Field Ion Microscopy. It explains the process of tomographic reconstruction, the use of wide-angle position-sensitive detectors, and the advancements in Atom-Probe Tomography. The lecture also delves into the detection speed and methods like electrical and laser pulsing. Various examples are provided, such as the reconstruction of Ni Alloy precipitates and InAs nanowires. The presentation concludes with discussions on tomography in electron microscopy, the Radon transform, and the challenges faced in achieving high resolution and overcoming the missing wedge problem.
