Introduction

We are conducting research aiming at the development of new measurement methods with the keyword of X-ray phase. The advantage of forming an image using the phase of X-rays is that extremely high sensitivity can be achieved. Since the discovery of X-rays in 1895, the usefulness of X-ray images has been recognized and used in a wide range of fields. However, since the contrast depends on the difference in X-ray absorption, there has been a drawback that the sensitivity is insufficient for weakly absorbing objects consisting of light elements, such as biological soft tissues and soft matter. Since the mid-1990s, a century after the discovery of X-rays, X-ray phase contrast methods have been attracting attention as a technology that can overcome this problem. Our laboratory has been responsible for the formation of its frontier. Currently, we are expanding the application of this technology to various substance observations, and are also working on practical applications such as medical image diagnosis.

Research Topics

We have research topics on various X-ray phase imaging methods based on the use of Talbot interferometers, Talbot-Lau interferometers, and their modifications that use transmission gratings:

• Optics of X-ray interferometry
• Development and application of X-ray phase microscopy
• Development and application of X-ray 4D phase tomography
• Neutron phase imaging
