the ability to store multiple holograms within a small volume of a storage material and to retrieve data pages with thousands of bits in parallel provides an attractive combination of high density and fast speed 体全息存储是一种适合高密度数据存储的光学存储技术,它同时具有存储密度高、数据传输率高、数据搜索时间短等优势。
the diffraction efficiencies of multiple holograms recorded and fixed in different number of batches are calculated and analyzed . if a special exposure schedules calculated based on the characteristic time constants of batch fixing scheme is incorporated for equalized diffraction efficiency, the greater the number of batches is, the higher the equalized diffraction efficiency of fixed holograms 结果表明,采用分批存储热固定技术,所分的批次数越多,经等衍射效率曝光时序记录后的全息图最终达到的等衍射效率值越高,并且所有全息图的写入曝光时间值越接近。
