Abstract
A method of uniform illumination for digital volume holographic storage system is proposed based on the speckle modulation technique by using a band-limited diffuser. The special diffuser is placed at a distance before the object plane to make the illumination light uniform, with approximate 4% rms power variation. Furthermore, vibrating the diffuser can help to reduce the speckle noise that roots in the Fourier imaging and recording system. The experimental results are given and it is shown that this method can reach a low raw bit error rate for the stored binary pages.
