Figure 8
Layout of the setup for combining DCT and section topography with a horizontal rotation axis and vertical detector. An absorption mask provides the line beam illumination on the sample. The irradiated section of the grain is projected almost perpendicularly (2θ ≃ 90°) onto the detector plane. An inline detector on which the section appears compressed as it diffracts is also shown for comparison. Grain maps can be acquired by either detector. |
