“…Because of the magnification, r was much larger than the system spatial resolution and the twin feature appears, while r is smaller than the spatial resolution in normal conditions, resulting in a differential phase image. When an incoherent X-ray source, such as a rotating anode source, is used, by placing a G0 grating upstream of a sample, the same concept is implemented in a laboratory-based X-ray microscope [75]. Recently, this configuration has been realized with a commercially available X-ray microscope (ZEISS Xradia 800 Ultra, Carl Zeiss X-ray Microscopy, Inc.; CA, USA).…”

Under the JST-ERATO project in progress to develop X-ray and neutron phase-imaging methods together, recent achievements have been selected and reviewed after describing the merit and the principle of the phase imaging method. For X-ray phase imaging, recent developments of four-dimensional phase tomography and phase microscopy at SPring-8, Japan are mainly presented. For neutron phase imaging, an approach in combination with the time-of-flight method developed at J-PARC, Japan is described with the description of new Gd grating fabrication.

“…Moving now to groundbreaking events, we would like to mention two groups of results. First, the implementation of hard-X-ray microscopy with a low-brilliance laboratory source, reported in 2011 by Kuwabara et al [ 21 ]. Second and in the opposite direction, the first steps towards hard-X-ray microscopy with free electron lasers [ 31 ].…”

Milestones like a lateral resolution below 10 nm, formerly a dream, appear now realistic [ 1 ].…”

The technology to focus hard-X-rays (photon energy larger than 1–2 keV) has made great progress in the past three years. The progress was particularly spectacular for lenses based on the Fresnel zone plate concept. The spatial resolution notably increased by a factor of three, opening up entirely new domains of application, specifically in biomedical research. As we shall see, this evolution is the result of a painstaking optimization of many different aspects rather than of a single technical breakthrough.

“…A further class of methods includes those termed Coherent Diffractive Imaging, which seek to exploit highly coherent beams to obtain coherent diffraction patterns from small samples or small regions of a sample, enabling very high-spatial resolution information to be extracted [ 30 , 31 , 32 ]. A number of these phase-contrast methods have been applied in materials micro-tomography [ 33 , 34 , 35 , 36 , 37 , 38 , 39 ].…”

X-ray phase-contrast imaging and tomography make use of the refraction of X-rays by the sample in image formation. This provides considerable additional information in the image compared to conventional X-ray imaging methods, which rely solely on X-ray absorption by the sample. Phase-contrast imaging highlights edges and internal boundaries of a sample and is thus complementary to absorption contrast, which is more sensitive to the bulk of the sample. Phase-contrast can also be used to image low-density materials, which do not absorb X-rays sufficiently to form a conventional X-ray image. In the context of materials science, X-ray phase-contrast imaging and tomography have particular value in the 2D and 3D characterization of low-density materials, the detection of cracks and voids and the analysis of composites and multiphase materials where the different components have similar X-ray attenuation coefficients. Here we review the use of phase-contrast imaging and tomography for a wide variety of materials science characterization problems using both synchrotron and laboratory sources and further demonstrate the particular benefits of phase contrast in the laboratory setting with a series of case studies.
