Abstract

Electron tomography (ET) has become an important technique for the 3D characterization of materials at the nanoscale. Recently, significant advances in transmission electron microscopy have allowed spatial, temporal and spectroscopic imaging at unprecedented resolution. Extending these innovative techniques to 3D is of great interest for many nanotechnology applications. It requires, however, the development of powerful tomography algorithms that are capable of producing reliable reconstructions from datasets that are often limited due to constraints about sample geometry, total electron dose and acquisition time. In this talk, we will present the basics of ET, and highlight some of the recent developments in reconstruction algorithms with an emphasis on compressed sensing (CS) approaches and their promising applications to 3D atomic imaging and multidimensional microscopy.
