Since the adoption of X-ray microscopy and tomographic imaging at synchrotron beamlines, continuous improvements in both spatial and temporal resolution have pushed the boundaries of nondestructive 3D imaging.
In recent years, a number of these synchrotron developments have been transferred to analogous laboratory-based instruments, in many cases offering comparable capabilities. For example, the latest lab X-ray microscopes have moved beyond the geometric limitations imposed by classical microCT design, incorporating optical elements to achieve resolution and contrast comparable to many synchrotron experiments, both on the micro and nanoscale. In addition, they have even adopted increasing numbers of imaging modalities, including phase contrast and diffraction contrast tomography. Also similarly to the synchrotron community, laboratory X-ray tomography systems have leveraged the nondestructive nature of the technique to foster increasing development of various types of in situ and 4D imaging experiments to probe structural evolution or degradation processes.
In this presentation, these themes will be explored by means of examples, along with a discussion of how XRM complements the existing suite of microscopy tools including light, electron, and ion systems.
