(a) A schematic diagram of Laue diffraction geometry. C is the crystal. O is the perpendicular foot of C on the imaging detector plane. D is the imaging distance from C to O. The Xf axis is along the opposite direction to x′. LauePt allows the detector to be rotated around x′ by an angle Φ (). [Φ = 90° corresponds to the reflection geometry widely used in Laue microdiffraction where the X-ray imaging detector is placed above the crystal (Gürsoy et al., 2022; Ulrich et al., 2011), while Φ = 180° corresponds to the forward transmission geometry.] (b) Crystal rotation along the diffraction vector G without affecting the diffracted wavevector kg. |
