3D X-ray microscopy & 3D X-ray microtomography
Our methods are based on the detection and subsequent localization of the degree of attenuation of the incident X-rays in the sample. The attenuation of X-rays by matter depends on both the chemical elements it consists of as well as the material density. The information about the varied X-ray absorption is encoded as grey values in the black-and-white images. The volume reconstruction facilitates, e. g., visualization of fabric compounds as 3D models, or preparation of virtual thin sections in any desired direction.
What kind of result do I get?
The result of our non-destructive 3D X-ray analysis is the reconstructed spatial distribution of X-ray attenuation within the object, in the form of a digital image stack or as an image volume. Each image consists of voxels (volumetric pixels) and allows quantitative analyses of volume and surface properties, or size distributions of different fabric compounds, etc. In addition, the transmission images can be supplied. Any analysis of the tomography data is possible in the context of scientific cooperation.
