Abstract
We present a new method to measure distortions in the entire crystal volume, down to a scale of 50 × 50 × 50 µm^3^ elementary volume. The method combines rocking curve imaging (RCI), section‐ and pinhole diffraction topography. As results we obtain three‐dimensional (3D) maps providing the integrated diffracted beam intensity and the fields of angular lattice misorientation. Angular misorientations down to 10^−5^–10^−6^ have been measured. In this paper the method is applied to one of the grains of a three‐grained ice polycrystal (tri‐crystal).
