| Research Abstract |
We have reported that the wobbling of a rotation stage, which usually causes the degradation of spatial resolution, in some cases brings high resolution. In this study, we have investigated the relationship between blurring during the acquisition of images and spatial resolution. As a result, we have clarified the relationships among the amplitude and patters of blurring, the number of projections and spatial resolution, providing the experimental conditions for high resolution images. We have also applied the findings to the in-situ observation of fatigue behaviors in a ductile cast iron, and succeeded in the clear observation of the fracture behavior at a reasonable high resolution.
