In this paper, to reduce the Bragg-mismatch problem of the dual-wavelength method, we record the hologram in the Dupont's photopolymer of thickness L=38µm and use a digital image data which has 78×104 bit/page. Also, to compensate the image magnification problem, a pair of cylinder lens consisting of 4F system behind the F 2 lens and proposed data matrix image processing technique is used. As a result, the raw BER through Gaussian fitting after extracting binary data is around 3.09×10 -6 .
