体全息存储技术

Volume holographic storage

体全息存储技术以其存储密度和数据读出率高及相关内容寻址等特点而具有广阔的应用前景。但体全息存储技术要同其它已经成熟的技术竞争 ,以在存储市场上占有一席之地 ,就必须注重发挥自己的优势。另外体全息存储技术要实现商品化 ,还有两个重要的问题需要解决。一是以较低的价格实现激光、空间光调制器和探测器阵列的对准。其次是要寻找合适的存储材料。对体全息存储来说寻找合适的存储材料仍是一个尚待解决的问题 ,至今还没有一种材料具有性能。

Volume holographic storage offers high density, fast data readout, and associative content addressable storage In order to contend with mature data storage technologies for the data storage market, holographic storage should attempt to capitalize on some of the unique attributes of holography Moreover, there are two major problems with the commercialization of volume holographic storage system need to be solved Firstly, it is a challenge to align the laser, SLM and CCD at low cost Secondly, the central issue is to find a suitable material Until now, there is not a single material satisfied the integrated requirement in performance, capacity and price
