Figure 8
Schematic of the TEDDI principle. The well defined incident and diffracted white X-ray beams define a diffraction lozenge which is also shown in the blow up. By traversing in x-, y- and z-axis directions the diffraction lozenge can be made to visit all required regions of the sample, collecting a stored energy-dispersive diffraction pattern at each region. These patterns are assembled later to form appropriate tomographic images. |
