Abstract
Holographic techniques applied to X-ray imaging Ralf-Hendrik Menk, ralf.menk@elettra.trieste.it Abstract Up to now standard X-ray imaging technologies, rely primarily on the amplitude properties of the incident radiation, and do not depend on its phase. This is unchanged since Rntgen's discovery [1] that the intensity of an X-ray beam, as measured by the exposure on a film or an equivalent X-ray detection device, was related to the relative transmission properties of an object. However, the new imaging techniques, which have been emerged, depend on the phase of the X-rays as well as the amplitude. Phase becomes important when the beam is coherent and the imaging system is sensitive to interference phenomena. Significant new advances have been made in coherent optic theory and techniques which now promise phase information in medical and material imaging. In this article an overview of the field with special regard to future applications will be given.
