[email protected] Received 5 April 2009 Published 19 August 2009 Online at stacks.iop.org/JPhysCM/21/364217 Abstract The various techniques for imaging diamonds with x-rays are discussed: x-radiography, x-ray phase-contrast imaging, x-ray topography, x-ray reciprocal-space mapping, x-ray microscopy; together with the characterization of the crystal defects which these techniques reveal. 1. Introduction may also be sharp characteristic peaks superimposed upon the continuous spectrum, characteristic of the target material. X-rays may be used to image whole diamonds, or selected These come from the brief promotion of electrons dislodged regions, by radiography or by using various techniques from target atoms to discrete higher energies. These (or other) employing a Bragg reflection for x-ray diffraction contrast.
