GI625 optical fiber data imaged on a Zeiss Versa XRM-500 microCT  at 12 tube voltages
This is tomography data as acquired using a commercial X-ray tomography instrument. We obtained reconstructions of a graded-index optical fiber with voxels of edge length 1.05 µm at 12 tube voltages. The fiber manufacturer created a graded index in the central region by varying the germanium concentration from a peak …
