Full-Field MicroXRF Imaging

To obtain volumetric information on the chemical composition inside objects, a full-field micro X-ray fluorescence (microXRF) imaging technique has been implemented. Opposed to the traditional point-by-point methods using confocal imaging, this new method collects complete 2D XRF projections of 3D objects without any scanning. And in contrast with EDX surface mapping in an SEM, having complete information from the entire volume allows creating 3D XRF images non-destructively by tomographic reconstruction. more
