Multiresolution X-ray CT Imaging of Fiber Reinforced Composite Materials
Résumé
We present an X-ray CT imaging method adapted to complex samples such as fiber reinforced composites, for which different spatial resolutions are needed to resolve the structures at different size scales: the whole sample, groups of fibers, individual fibers and matrix material. We developed an efficient algorithm which uses two sets of tomographic data acquired in a zoom-in CT configuration and which outputs a bi-resolution image.
The method was validated on simulated data and we present experimental results for two different samples.
