Applications
(Absorption, Dark-field, and Phase Images)

CFRP Laminate Layers Plastic Bottles

This is a sample scan of a material in which the angle of a prepreg of fibers aligned along one direction is changed to This is a sample scan of a plastic spray bottle. With a phase image, it is possible to observe the voids in the plastic,
build up the laminate layers. It is evident from the cross-sectional images that there are three orientation directions, without the impact of artifacts due to a spring. In addition, the internal structure of the sample where different types
and from the VR image, these have evidently been used by turns in the laminate. of plastic are joined can be observed using absorption and phase images due to the difference in the absorption
coefficients and densities.

This is an example of the analysis of fiber orientations in a laminate material, woven with carbon fibers.
Tomatoes
This is a sample scan of a tomato. The internal structure of the vegetable can be observed even if there is a high
moisture content.

Cross-Sectional Image (Dark) Cross-Sectional Image (Dark) VR Image (Dark)
This is a sample scan of a material in which pieces of carbon tape with random orientations are used to build up the
laminate layers. X-rays scattered along the orientation of the grating are detected, enabling the fibers oriented along
these directions to be detected. Upper Jaw Tooth Plate of an Elephant Shark

This is a sample scan of an upper jaw tooth plate of an elephant shark.
