(a) Schematic representation of the experimental setup of the 3DXRD microscope at ID11 (ESRF, France). A glass capillary filled with calcium sulfate hemihydrate grains was mounted on the rotation stage and translated in the y direction. During the rotation, the diffraction spots coming from the grains were collected on the detector. A beamstop was placed in front of the centre of the detector in order to absorb the direct beam and prevent damaging the detector. (b) Segmentation method workflow with the ImageD11 software: from the extraction of the diffraction peaks from one rotation (0 < ω < 180° at one Δy), to the extraction of the peaks of the full data set, and finally the azimuthal integration of the diffraction pseudo-rings and representation of the peaks in the 2θ–η diagram.
