摘要
体全息存储系统中通常采用SLM和CCD作为输入输出器件。SLM和CCD的性能包括填充因子、对比度和像素形状 ,这些性能会对像面页内像素间干涉程度产生很大的影响 ,进而影响页内噪声的大小。针对这一问题 ,首先进行了理论分析 。
Spatial Light Modulator (SLM) and CCD detector are generally used as input and output devices in volume holographic data storage system. The performances of SLM and CCD, including fill factor, contrast and shape of the pixels, affect the extent of intrapage inter pixel interference at imaging plane, consequently influence the magnitude of intrapage noise. To this issue, theoretical analysis is given first, then by computer simulation, conclusion is drawn.
