Holographic multiplexing in photorefractive and photochromic polymers - associative optical memories for high-throughput screening

全息多路复用实验应在Köln大学进行，下一代光折变和光致变色低分子量玻璃将在法国科学院卡尚研究所开发，并在斯特拉斯堡IPCMS进行表征和建模。全息图以一种可以同时读取的方式存储，允许图像的光学相互关联。特别是，如果图像来自生物（化学）传感器阵列，该技术将允许快速测试交叉灵敏度，同时考虑所有通道。因此，该项目将对高通量筛选等未来医疗应用产生重大影响。该项目的预期产出是开发具有独特光折变和/或光致变色特性的新型玻璃化合物，对其进行深入表征，最后首次实现用于评估和生物（化学）传感器阵列相互关联的联想光存储器。该项目汇集了三个团队，他们在有机合成化学、材料科学、物理和光学计算领域拥有理想的专业知识。这种独特的星座保证了项目的成功。

Holographic multiplexing experiments should be performed at the University of Köln with the next generation of photorefractive and photochromic low-molecular-weight glasses to be developed at ENS Cachan and to be characterized and modeled at IPCMS Strasbourg. The holograms are stored in a way that they can be all read at the same time, allowing for optical cross-correlation of images. In particular, if images originate from bio (-chemical) sensor arrays, this technique will allow to rapidly test for cross-sensitivities, taking into account all channels simultaneously. Thus, the project will have a strong impact on future medical applications such as high-throughput screening. The expected output of the project is the development of novel glassy compounds with unique photorefractive and/or photochromic properties, their in-depth characterization, and finally the first realization of an associative optical memory for the evaluation and the cross-correlation of bio(-chemical) sensor arrays. The project brings together three teams with ideally compatible expertise in the fields of organic synthetic chemistry, material science, physics and optical computing. This unique constellation guarantees a successful outcome of the project.
