| Outline of Final Research Achievements |
X-ray phase imaging has been attracting attention since it can be applied to polymers and biological soft tissues consisting low-Z elements, which are not imaged clearly with conventional X-ray imaging methods. The study performed so far was for static samples during imaging. However, dynamical imaging is desirable to understand the property and function of materials.
We studied the methods for high-speed phase imaging and four-dimensional X-ray phase tomography with X-ray Talbot or Talbot-Lau interferometry. More concretely, we developed methods in combination with white synchrotron radiation and storoboscopic methods for periodic phenomena as a breaktrough to dynamical X-ray phase imaging.
