ABSTRACT We report on the design and experimental realization of a 2D x-ray grating interferometer. We describe how this interferometer has been practically implemented, discuss its performance, and present multidirectional scattering (dark-field) maps and quantitative phase images that have been retrieved using this device.

    ABSTRACT: The gold-coated cross-grating is investigated to simultaneously improve the diffraction efficiency, signal contrast and optical subdivision in heterodyne grating interferometer (HGI). Based on the theories of Fresnel-Kirchhoff diffraction integral and rigorous coupled wave analysis (RCWA), the diffractive characteristics related to diffraction efficiency, wavelength selectivity and polarization dependency are analyzed. The analysis reveals that grating pitch less than twice of the incident wavelength ought to be adopted here to avoid the second-orders, and longer wavelength is preferred to achieve high diffraction efficiency in the visible region. Meanwhile, the equivalent efficiency for TE and TM polarization, probably up to 18.32% at the wavelength of 632.8 nm, can be obtained with normal incidence which results in a signal contrast of 100% theoretically. Additionally, an eightfold optical subdivision method with cross-gratings is proposed for HGIs, and it is applicable to nearly all the existing two-dimensional (2D) optical configurations. The experimental tests on diffraction field, polarization dependency and signal contrast are performed. The results show reasonable consistency with the theoretical analysis, which validates the capability of cross-gratings for HGIs.

    ABSTRACT: It was recently established that the pixel-wise ultra-small angle x-ray distribution can be retrieved with grating interferometry. However, in these one dimensional approaches the contrast was limited to the direction orthogonal to the structure of the line gratings. Here, we demonstrate that sensitivity in two contrast directions can be achieved by using two pairs of crossed line gratings and by adapting scan procedures and data analysis accordingly. We demonstrate the retrieval of two-dimensional scattering distributions with grating interferometry, thus overcoming the previously reported limit of seven obtainable, complementary contrasts. In addition, we give further evidence for the superiority of the signal-to-noise ratio for the dark-field contrast, if a deconvolution-based instead of the standard analysis is utilized.

    ABSTRACT: Two phase contrast imaging techniques, namely two dimensional grating interferometry and X-ray speckle tracking (XST), have been combined with the use of a Fresnel Zone Plate (FZP) for application to X-ray microscopy. Both techniques allows the phase shift introduced by a sample on a hard X-ray beam in two dimensions, to be recovered with a high sensitivity and low requirements on transverse and longitudinal coherence. Sub-micron phase imaging of carbon fibres was achieved using the two methods thanks to the high magnification ratio of the FZP. Advantages, drawbacks and differences between these two techniques for X-ray microscopy are discussed.
