WebSince ion channeling is dependent on atomic spacing, the family of {uvw} directions will channel identically and therefore produce a similar grayscale image signal. As the angular width for ion channeling is so large, determining grain boundary positions (e.g., for grain size measurements) requires multiple images at numerous tilt directions.
