It is difficult to obtain a clear atomic image from a measured X-ray fluorescence hologram, because the holographic undulation in the angular distribution of the X-ray fluorescence intensity is feeble. We introduce here our numerical data process to reconstruct an atomic image from the SrTiO3 (001) hologram data reported in a previous paper [J. Kawai et al.: Anal. Sci. 14 (1998) 903]. The holographic oscillation, which could not be seen in the raw data, was revealed by the Savitzky-Golay smoothing method. We also considered the effect of the hologram size on the reconstructed image of Sr atoms, and found that the spatial resolution of the image became higher with an increase of the size in the hologram.
