Details and application examples of Lab-based DCT Advanced Acquisition.

Find inspiration in recent grain maps representing a variety of different material classes, sample geometries and grain sizes.

Inclusive booklet introducing the non-destructive 3D crystallographic imaging with lab-based diffraction contrast tomography.

To help our users gain full potential we developed a Neper pipeline from a voxellated lab-based DCT grain map output to a simulation-ready input mesh.

The pipeline is documented and available at github, while example data can be downloaded from the Materials Data Facility, see details in the Application Note.

What can planetary scientists infer about the conditions of meteorite formation from a combination of absorption CT and DCT on olivine grains? Quite a lot it turns out! See the Application Note for details.
