Carbon-fiber reinforced plastic (CFRP) contains carbon-fiber fabric with bundles in two orthogonal orientations.

Carbon-fiber reinforced plastic (CFRP) contains carbon-fiber fabric with bundles in two orthogonal orientations. Shown 3D volume rendering reveals object morphology in absorption contrast and also orientation-selective information for carbon fibers in dark-field (scattering) contrast. The combined image visualizes both fiber orientations and plastic filler simultaneously.

Electronics

The electronic chip in credit cards is attached to the reverse side of the metal contacts

The electronic chip in credit cards is attached to the reverse side of the metal contacts. This virtual slice through the reverse side of chip insert in absorption contrast (left) displays all metal contacts,the die attach and thin wires for connections to the contacts. The phase-contrast virtual slice (right) reveals details of the glue layer with air bubbles,used to attach the chip assembly to the plastic frame of the card and chip encapsulation.

Biomedical

virtual slice through a rat knee

Reconstructed virtual slice through a rat knee in absorption contrast (left) allows clear imaging of bone microarchitecture, but not of surrounding soft tissues. The virtual slice obtained from the same place in phase contrast reveals more details in the soft tissue including cartilage and ligaments between the bones.

Diamonds

3D volume rendering of a 5 carat rough diamond

3D volume rendering of a 5 carat rough diamond: absorption contrast visualizes the external surface and metal-oxide inclusions. The scattering image clearly displays all internal defects as well as a massive carbon (graphite) cluster in the left bottom corner. This cluster can be visually seen as a black inclusion, but does not appear in the absorption image due to identical chemical composition of graphite and diamond.

Food

adsorption image through a tomato

The adsorption image through a tomato (left) shows very few internal details, but phasecontrast (middle) and especially dark-field images (right) show all internal details including the water and air transportation network and seed traces.

reconstructed slice of a strawberry’s internal structure

The reconstructed slice of a strawberry’s internal structure in absorption contrast displays most morphological features. The dark-field (scattering) adds significant functional information on the water transportation network connected to the leaves at the top.
