The method is based on the concept thatthe position of diffraction spots depends on the orientation of individual grains. The two-dimensional detector hasthe ability to collect abundant diffraction information in seconds, thus it can be determined rapidly and accuratelywhether a series of diffraction spots come from the same grain.
