| Research Abstract |
An x-ray microscope with a zoneplate was constructed using 5.4 keV x-rays from the synchrotron radiation source Photon Factory BL3C. A quantitative differential phase image was successfully obtained by introducing a scanning knife-edge filter at a back focal plane of an objective zone plate. In phase tomography, a reconstructed value of polystyrene beads was homogeneous in the standard deviation of 5.4%. Cartilage and spores of plants could be observedin 3 dimensions with good contrast.
