Filter Design Method

Custom image filter design method is suggested in this research for holographic data storage (HDS) system. While the previous research requires the high precise point spread function (PSF) as the deconvolution filter, proposed method calculated image restoration filter without the information of optical system. It could be possible because of the unique characteristic of HDS data page. We use the simple iteration method to obtain the image restoration filter. The performance of custom image filter is verified both simulation and experiment. As a result, it shows the acceptable performance in BER improvement in HDS system.
