Abstract
In coherent X-ray diffraction imaging, speckles on a coherent diffraction pattern must be sampled at intervals sufficiently finer than the Nyquist interval, which imposes an upper limit on the sample size. To overcome the size limitatio...
<title>Abstract</title>The quest for understanding the structural mechanisms of material properties and biological cell functions has led to the active development of coherent diffraction imaging (CDI) and its variants in the hard X-ray regime. He...

Abstract
The optical transfer function (OTF) of an inverse-phase composite zone plate under incoherent illumination was numerically evaluated by convoluting the point spread function (PSF) and transmission distribution of a model sample with gra...
A new apparatus has been constructed for hard x-ray micro-imaging and microdiffraction experiments at BL24XU of the SPring-8. The new apparatus can be used as a scanning microscope mainly for mapping measurements of trace elements, a microdiffract...
We have developed a high-resolution x-ray microdiffraction system at the BL24XU of the SPring-8. This system uses a focused beam produced by using a zone plate combined with a narrow slit. The size of the focused beam is 0.32 mum vertically and 1....

We have demonstrated to form an x-ray microbeam with a narrow angular divergence in both vertical and horizontal polarization directions of synchrotron radiation x-rays by the use of successive asymmetric Bragg reflections. Using the highly parall...
