We use the conception of pixel-matched spread function (PMSF) to analyze the physical process of intra-page cross talk
in a holographically imaged data page, and design an arithmetic to suppress the intra-page cross talk generated in the
reconstructed data page due to limited aperture of imaging optical system. By applying this arithmetic to a data page of
512×512 pixels captured from our CCD, the raw bit error rate (BER) decreased from 1.1×10<sup>-3</sup> to 2.4×10<sup>-4</sup>.
