Abstract
Amplitude-modulated collinear holographic data storage technology has high storage density, fast data transfer rate and stable system. The key to realizing system operation is to decode the amplitude code quickly and correctly. We proposed a decoding method based on 3:16 amplitude code. We used the convolution calculation to locate the sync mark point of every sub-page in the data page quickly and calculated the magnification rates among sub-pages to get the correct sub-page image segmentation. Taking the bit error rate as the evaluation standard, we verified our method successfully in different image quality.
