| Research Abstract |
Using the X-ray phase measurement techniques with X-ray transmission grating(s), including X-ray Talbot interferometry, in combination with an X-ray imaging microscope with a Fresnel zone plate, X-ray phase-sensitive imaging microscopy has been developed, enabling high-sensitive and high-resolution observation for weakly absorbing objects, such as polymers and biological tissues. In addition, by repeating the phase measurement at plural projection directions, three-dimensional image reconstruction of the refractive index (X-ray phase tomography) has also been demonstrated.
