The superstructure in Bi2(Sr0.9La0.1)2CoO(y) has been studied by the two-stage image-processing technique consisting of image deconvolution and phase extension; and based on the combination of high-resolution electron microscopy and electron diffraction. All unoverlapped atoms including oxygen are resolved in the final projected potential map of resolution of about 1 Å. The structure modulation is seen clearly. It is caused by the fluctuation of both atomic positions and occupancy.
