摘　　要：体全息存储具有大的存储密度、高的数据传输速率和快的读出时间等优点。虽然其基本原理早在50多年前已经被提出,但是直到现在仍然没有产品出现。本文首先分析了限制体全息存储技术发展的几个主要原因;然后,对体全息存储的几项关键技术,包括存储材料、实用部件和噪声抑制,进行了阐述;最后,给出了体全息数据存储系统的应用前景。Volume holographic storage has the attractive features of high capacity, fast transfer rates and short access times. The principle of holography was established over 50 years ago. And yet, today, we still do not have a product. The problems, which limited the development for many years, are accessed. Then, we review the technologies, including storage materials, components and combating noise, which either are in use today or are likely to play a role in the near future. Finally, some applications of the volume holographic data storage system are introduced.
