Development of Next-Generation Coherent X-ray Imaging Method and Its Applications
Coherent X-ray diffraction imaging is a microscopy technique in which a sample is irradiated with coherent X-rays and then the sample image is reconstructed by applying phase retrieval calculations on the diffraction pattern. Since coherent X-ray diffraction imaging does not require an objective lens, it is possible to achieve high spatial resolution imaging independent of the lens performance. We have been developing novel coherent X-ray diffraction imaging methods such as high-spatial-resolution imaging with total-reflection mirrors, three-dimensional imaging with multi-slice method, spectroscopic imaging combined with X-ray absorption spectroscopy, and single-shot imaging with triangular aperture, and their applications to materials and bioimaging. Compared to the third-generation synchrotron radiation facility, SPring-8, next-generation synchrotron radiation (NGSR) in Tohoku can provide more intense coherent X-rays in the soft X-ray and tender X-ray regions. We will propose a coherent X-ray diffraction imaging method based on a new principle by utilizing the light source performance of NGSR and apply it to imaging research in a wide range of fields.

Examples of sample observation using coherent x-ray diffraction imaging
- Message
- I would like to propose a new imaging method using coherent X-rays to change the way we observe materials, and in 10 years, I would like to achieve atomic resolution, which has never been achieved with X-rays.
