Transmission geometry for strain profiling on layered polycrystalline structures. The sample is scanned in the indicated z direction and the scattering angles are measured. The height of the line focus limits the spatial resolution to which strain gradients may be detected. Experiments were performed employing both the Laue–Bragg monochromator/multilayer combination and the Laue focusing optics to produce narrow line foci of 4 µm and 1.2 µm height, respectively. |
