U.S.-Germany Cooperative Research: Photorefractive Materials for Holographic Storage

9910005 psaltisthis奖支持德美特里Psaltis和三个学生从加州理工学院的合作Karsten Buse Osnabrueck大学物理系的,德国。该项目将重点研究光折变晶体的体全息记录。到目前为止，主要的问题是全息数据在读取过程中被擦除，使其不适合存储设备。这个问题的解决方案在于使用双掺杂晶体，而这次合作将优化可用于制造可重写存储设备的材料。这两个团队将共同模拟该方法成功的物理机制，通过测试其他掺杂剂和晶体来提高该方法的性能，并演示包含双掺杂晶体的持久全息存储系统。

9910005PsaltisThis award supports Demetri Psaltis and three students from the California Institute of Technology in a collaboration with Karsten Buse of the Department of Physics at the University of Osnabrueck, Germany. The project will focus on the study of volume holographic recording in photorefractive crystals. The major problem up to now has been that the holographic data gets erased during read out, making it unsuitable for storage devices. A solution to the problem lies in the use of doubly-doped crystals, and this collaboration will optimize the materials which could be used to make rewritable storage devices. Together the two groups will model the physical mechanisms responsible for the success of the method, improve the performance of the method by testing other dopants and crystals, and demonstrate a persistent holographic memory system incorporating doubly-doped crystals.
