For a two-dimensional constant-weight block code, we show that the recording density is proportional to code rate and the second power of the size of the bright point. Second, we show four constant-weight block codes (two 2:16 codes, a 4:24 code, and

Multilayered waveguide holography (MWH) is one of a number of page-oriented data multiplexing holographies that will be applied to optical data storage and three-dimensional (3D) moving images. While conventional volumetric holography using photopoly

We present an expression for the probability density functions of the ON and OFF pixels of a 2:N constant-weight block code to estimate the raw bit error rate (BER). We also show that they are similar to Gaussian ones through an analysis of an actual

In this paper, we discuss an optical design for multilayered waveguide holographies that employ an orthogonal aperture multiplexing (OAM) technique. The OAM is a type of spatial multiplexing technology that can be applied to thin film holographies. T

Our two-dimensional modulation code improves the decoding accuracy of images reconstructed from a multilayered waveguide holographic memory that have been translated, rotated, and distorted with respect to the image detector. The reconstructed images

Two-dimensional digital image reproduction in a hologram memory causes incorrect decoding due to image distortion. In order to correct image distortion, the position coordinates of the four corners of the reproduced image are detected by template mat
