The depth resolution of a soft X‐ray hologram is much worse than its transverse resolution because a single soft X‐ray hologram has a small numerical aperture. To obtain a three‐dimensional image, in‐line holograms of a specimen were recorded from various directions and reconstructed to obtain two‐dimensional projection data. Then, a three‐dimensional reconstruction was performed by back‐projection of these reconstructed holograms. Three‐dimensional images of a tungsten wire of diameter 10 µm and a fossil of a diatom were obtained.
