The three-dimensional atomic image of YB56 was obtained by inverse Fourier transformation of three-dimensional phases and amplitudes in three high-resolution images along [100], [110] and [111] of YB56 crystals. After crystallographic image processing, the image directly showed the three-dimensional potential map of the crystal, which showed (B12)13 clusters and Y atom positions. The present method would be useful for three-dimensional structure analysis in nanoscale regions. 相似文献

Nuclear magnetic resonance (NMR) imaging can be applied non-destructively to detect physical flaws in fibre-reinforced ceramics
in the green state. This paper describes the application of NMR imaging to detect physical flaws such as fibre-agglomerates
and pores in ceramic matrix composites made by slipcasting. Application of this technique to detect and eliminate the composites
with these flaws in the green state will result in considerable savings in processing time and in the cost of components or
prototypes fabricated by slipcasting. 相似文献

We propose a depth extraction method by using the correlation between an elemental image and a periodic function in computational integral imaging. Because each elemental image corresponds to a different perspective of the three-dimensional (3-D) object, an elemental image is regarded as the sum of the periodic spatial frequencies depending on the depth of a 3-D object. In this regard, we analyze the property of correlation between the same periodic functions and vice versa. To show the feasibility of the proposed method, we carried out our experiment and presented the results. 相似文献
