US-Germany Cooperative Research: Photorefractive Materials for Holographic Information Systems

该奖项资助Demetri Psaltis和加州理工学院的两名学生，他们与德国波恩大学物理系的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，这种合作将优化材料，这种材料可以用来制造可重写的存储设备。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提高该方法的性能，并展示一种包含双掺杂晶体的永久性全息存储系统。该项目也有一个教育目标。该项目将允许参与的研究生从在另一个国家进行研究中受益。他们将培养对周围世界的高度欣赏，同时也学习重要的新技术技能。

0233988PsaltisThis award supports Demetri Psaltis and two students from the California Institute of Technology in a collaboration with Karsten Buse of the Department of Physics at the University of Bonn, 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.The project also has an educational objective. The project will allow the graduate students involved to benefit from performing research in another country. They will develop a heightened appreciation of the world around them while also learning important new technical skills.
