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 total-reflection zone plate (TRZP), which is a reflective grating that generates a line focus of hard X-rays, was developed. Newly designed TRZPs, introducing a laminar grating concept, were fabricated with various zone parameters. The focusing ...

We have developed a four-dimensional (4D) x-ray microcomputed tomography (CT) system that can obtain time-lapse CT volumes in real time. The system consists of a high-speed sample rotation system and a high-frame-rate x-ray imager, which are insta...

We designed point focusing total-reflection zone plates (TRZPs): a double linear type TRZP in Kirkpatrick-Baez arrangement, a conical TRZP, and an open conical TRZP. In this paper, we show detail characteristics of the open conical TRZP, which is ...
10TH INTERNATIONAL CONFERENCE ON X-RAY MICROSCOPY 1365 100-103 2011年
A circular type multilayer Laue lens (MLL) has been designed and fabricated. A graded-thickness multilayer was deposited on a tapered wire core by using a magnetron sputtering system. A combination of MoSi2 and Si was chosen as the multilayer mate...
