We present a proof of concept for a new approach for Energy Dispersive X Ray Diffraction (EDXRD) imaging in “line parallel” configuration. It follows an inverse problem approach using a physical model of the diffraction phenomenon. Using this approach, we show that it is possible to achieve a spatial super-resolution of poly-crystalline objects (i.e. estimating more voxels than detectors).
