Abstract

This paper proposes a method to increase the recording density of binary data pages in holographic memory. The recording density is increased by decreasing the rectangular aperture size on a Fourier plane. To extract the original data page from the low quality image, a four-step phase mask is designed. The principle of the proposed method is numerically verified.
