Figure 3
(a) Diffraction geometry of a synchrotron experiment in transmission; the samples are rotated around the Y axis (ω rotation) for better pole figure coverage. The scattering vector for each Debye ring produces a small circle on the orientation sphere in (a). In the corresponding pole figure (b), we are looking at the projection of this small circle along the Y axis (from top). The small circle in this projection appears as a pair of lines that are drawn schematically as parallel straight lines. For tilted orientations the lines are rotated around the pole figure center by ω. The indicated `pole' in (a) corresponds to the scattering vector for a specific Debye ring diffracted at a 2θ angle and at an angle η along the ring.
