The Quality Improvement on the Image of Volume Holographic Memories with the Extrapolation in Frequency Domain

The relation between low-spatial-frequency components and high-sptial-frequency components, of spatial-limited image was studied, based on the sampling theorem in frequency domain. It was demonstrated by the result of computer simulation. The possibility of utilizing extrapolation in frequency domain, from low-spatial-frequency components of spatial-limited image to extract high-spatial-frequency components, for volume holographic memories is discussed.
