9413013 Houde-Walter Funding for basic research is most compelling when it is connected to national needs. This proposal specifically addresses a fundamental issue in glass science (ion exchange) which is closely related to manufacture of medical instruments which are used in minimally invasive surgical procedures, resulting in shorter hospital stays, less trauma to the patient and significantly lower costs of treatment and recovery. Many other optical systems, such as those used in remote sensing for environmental monitoring and in distance sensing needed in intelligent automobiles, either use or are likely to use in the imminent future, ion-exchanged glass micro-optics. The scientific goal of this work is to better understand the relation between structure, composition and properties of commercially important glasses and to shorten the product development time of photonic components (gradient-index micro- optics) that are fabricated by ion exchange. Relevant structural chemistry parameters will be obtained by x-ray absorption spectroscopy and will serve as constraints on molecular dynamic modeling of the same glasses. Changes in the cation environment with composition and processing conditions will be investigated in the lab and related to transport behavior and the resultant index profiles. The transport properties will also be observed in computer experiments of ion exchange and the simulated effect of minority components on transport behavior will be used to guide the tailoring of glass compositions to particular gradient-index and micro-optic applications. The results will be incorporated in prototype lenses at Gradient Lens Corp., and a small high tech company in Rochester, NY, that manufactures micro-optics and gradient-index lenses. By the third year on the project we will have incorporated a large repertoire of diffusion parameters and models into a commercial lens design program and will have designed, toleranced, fabricated and tested the qual ity of an ion- exchanged gradient-index lens system. ***

9413013 Houde-Walter用于基础研究的资金与国家需求相关时最引人注目。 该提案专门解决了玻璃科学（ION Exchange）中的基本问题，该问题与制造医疗工具密切相关，该医疗工具用于微创手术程序中使用，导致医院较短，对患者的创伤较小，并显着降低了治疗和康复成本和康复成本。 许多其他光学系统，例如用于环境监测的遥感和智能汽车所需的距离感应中的光学系统，无论是使用还是在即将来临的未来，离子交换的玻璃微观上使用。 这项工作的科学目标是更好地了解商业上重要眼镜的结构，组成和特性之间的关系，并缩短由ION Exchange制造的光子成分（梯度 - 指标微光学）的产品开发时间。 相关的结构化学参数将通过X射线吸收光谱获得，并将作为对同一玻璃分子动态建模的约束。阳离子环境的变化将在实验室中研究，并与运输行为和所得指数概况有关。 在离子交换的计算机实验中也将观察到运输特性，并且少数族裔组成对运输行为的模拟影响将用于指导玻璃成分对特定的梯度指数和微观光电应用。 结果将纳入梯度镜头公司的原型镜头，以及纽约州罗切斯特的一家小型高科技公司，该公司生产微观和梯度索引镜头。 到该项目的第三年，我们将将大量扩散参数和模型的曲目纳入商业镜头设计计划中，并将设计，容忍，制造和测试，并测试了一个离子交换的梯度索引镜头系统的质量。 ***
