High Resolution 3D Reconstructions of Rocks and Composites

摘要

Ten μm resoltuion 3D representations of different media, were obtained with a laboratory computer microtomograph develo- ped form an electron microprobe column. From the original electron microprobe, only minor modifica- tions have been required, indeed several of the utilities of the microprobe have been used to ensure high resolution radiography (2 μm). The impact of the electron beam focused onto a thin film is used to form a "point" X-ray source and the radiographic image f the sample is acquired on a CCD camera.
