🚨New Preprint: "Angular Resolution Enhancement of Electron Backscatter Diffraction Patterns" by @bmatb.expmicromech.com and @tbizh95.bsky.social

arxiv.org/abs/2509.23039

Figure from the paper which shows that you can get an angular improvement in the EBSD pattern by using a super resolution method, above what is expected from simply counting longer.

On behalf of @expmicromech.com - the latest version of AstroEBSD is released, adding the newly developed AstroECP tool to our toolbox (see our preprint announcement). Also we (finally) tidied up the readme files, added descriptions of new features over the years, and created a change log.

Exciting times - a brand new Thermo Fisher Scientific Apreo Chemisem scanning electron microscope, equipped with EDX and EBSD, is being commissioned for us at UBC - with support from Systems for Research.

This instrument will enable us to develop highly automated materials characterization methods.
