Abstract
An image reconstruction model for the collinear holographic data storage (CHDS) system is proposed and analyzed. The analytical solution for the reconstructed image by the CHDS system is derived based on the first Born approximation and scalar diffraction theory. This expression shows the CHDS system is not a linear space-invariant system. A page-oriented simulation method is desired for a rigorous analysis. By applying the fast Fourier transform method, a page-oriented simulation method for the CHDS system is presented. The influence of the reference pattern and the media thickness on the quality of the image reconstructed from the holograph is investigated. The fill factor of the reference pattern is the key parameter for the quality of the reconstructed image.
