Phase Contrast Imaging in Laboratory

Since Roentgen's discovery of X-rays, just over a century ago, the vast majority of radiographs have been acquired and interpreted on the basis of absorption contrast. The recent development of X-ray phase contrast imaging techniques opens up a new opportunity especially for weakly-absorbing objects. Spatial and temporal coherence of X-ray synchrotron radiation permits to realize phase contrast imaging with ideal conditions. But it is possible to set up phase contrast imaging in laboratory. Laboratory phase contrast imaging can provide new solutions in an industrial context. The aim of this paper is to present the different solutions to perform phase contrast imaging in laboratory: - classical micro focus X-ray tube, - X-ray ultra microscope (XuM) developed by an Australian team - table top synchrotron developed by a Japanese team, - multilayer, - poly-capillary.
