Phase contrast imaging takes advantage of the fact that different materials have different refractive indices. This produces a phase shift in the X-rays passing through the sample. By placing the imaging detector at a specific distance from the sample, interference between waves can be used to enhance contrast in the image.
Whilst phase contrast imaging is possible using laboratory techniques, the highly coherent X-rays beams make it possible to gather data with much simpler instrumentation. In addition, it is possible to achieve higher spatial resolution, and to carry out phase contrast tomography, where three dimensional images are created from two dimensional scans.
Phase contrast imaging enables the examination of crack growth and fatigue in materials under stress, which is of particular importance in the aerospace and engineering industries. It is particularly useful for enhancing the contrast of surfaces and interfaces in samples, which would not be visible using absorption contrast.
DIAD will be the a dual beam instrument capable of imaging and diffraction at the same time at the micron scale. The beamline will enable in-situ experiments aiming to resolve the 3D microstructure (via imaging) and phase constitution/strain state of material (via diffraction) in quasi-simultaneously matter with switching times of a few Hz between analysis techniques.More information

The Hard X-ray nanoprobe I14 beamline is a dedicated facility for nanoscale microscopy. The central theme of the beamline is the ability to obtain structural and chemically-specific information on a full range of materials (inorganic/organic) under both static and real (e.g. wet, heated, in-situ strain) conditions.More information
I13 is Diamond’s longest beamline, dedicated to imaging, tomographic and coherence experiments across the biological, medical, geological, material, engineering and archealogical sciences.More information
I12 is a high-energy beamline principally for Material Science, Engineering and Processing Science. The instrument’s main focus is to allow in situ studies of samples in environments as close as possible to real world environments using imaging, tomography, diffraction and small-angle scattering. I12 is particularly well suited to study large or dense objects and offers a unique sample and environment installation facility for weights up to 2000 kg.More information
I08-1 is the soft X-ray ptychography instrument at Diamond. The instrument is designed for ptychographic imaging, spectromicrosopy and tomography. I08-1 (J08) is currently in its commissioning/ optimisation phase and is open for proposal applications,More information
