Study of the three-dimensional distribution of defects in crystals by synchrotron radiation diffraction tomography

The three-dimensional (3D) distribution of defects was investigated in several crystals by synchrotron radiation diffraction tomography. This experimental procedure combines white-beam synchrotron radiation section topography with electronic image recording and computer data processing. A scan involving many section topographs is performed with the same Bragg reflection, resulting in a stack of section topographs containing the 3D information.
