Phase-Contrast X-ray Microtomography

The purpose of this project is to implement a method for phase-contrast x-ray tomographic imaging, based on speckle deflectometry, that will allow imaging of compound materials with only small differences in density, too small to resolve and separate using conventional absorption contrast. The aim is to implement this technique so that it can be utilized both in a standard lab-based microtomography systems as well as using synchrotron light, for example at the ForMAX beamline at Max IV.

The project is motivated from the need of detailed micro-mechanical investigations of new material combinations made possible with new manufacturing processes. One example is modified wood obtained by adding nano-scale inorganic substances to enhance mechanical properties and better resistance towards sunlight, heat and moisture.
