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

0233988该奖项支持Demetri Psaltis和来自加州理工学院的两名学生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，而这次合作将优化材料，可用于制造可重写的存储设备。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。该项目还有一个教育目的。该项目将使参与的研究生受益于在另一个国家进行研究。他们将在学习重要的新技术技能的同时，提高对周围世界的欣赏。

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.
