A soft-x-ray Gabor hologram was recorded directly by means of a cooled backilluminated CCD camera, and numerical reconstruction was performed. Synchrotron radiation from a bending magnet with beam line 11A at the Photon Factory, National Laboratory for High Energy Physics, Japan, was used. X rays were monochromatized to a wavelength of 2.34 nm with a grasshopper monochromator and focused on a pinhole of diameter 1.0 μm with a zone plate. A specimen was illuminated with soft × rays transmitted through the pinhole, and a shadowgraph with a magnification ratio of 33 at the CCD plane was digitized directly. The transverse resolution of the reconstructed image was estimated to be 1.5 μm, which was in good agreement with a theoretical value.
