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

9910005Psaltis该奖项支持Demetri Psaltis和加州理工学院的三名学生，他们与德国奥斯纳布鲁克大学物理系的Karsten Buse合作。该项目将重点研究光折变晶体中的体全息记录。到目前为止，主要的问题是全息数据在读出过程中被擦除，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，这种合作将优化可用于制造可重写存储设备的材料。这两个小组将共同对该方法成功的物理机制进行建模，通过测试其他掺杂剂和晶体来改善该方法的性能，并展示一种包含双掺杂晶体的永久性全息存储系统。

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.
