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基础研究的资金是最引人注目的，当它连接到国家的需求。 该提案专门解决了玻璃科学（离子交换）中的一个基本问题，该问题与微创外科手术中使用的医疗器械的制造密切相关，从而缩短住院时间，减少对患者的创伤，并显著降低治疗和康复成本。 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传感的光学系统，使用或可能在不久的将来使用离子交换玻璃微光学器件。 这项工作的科学目标是更好地理解商业上重要的玻璃的结构、组成和性能之间的关系，并缩短通过离子交换制造的光子组件（梯度折射率微光学器件）的产品开发时间。 相关的结构化学参数将通过X射线吸收光谱法获得，并将作为相同的玻璃的分子动力学建模的约束。将在实验室中研究阳离子环境随组成和加工条件的变化，并与传输行为和所得折射率曲线相关。 还将在离子交换的计算机实验中观察传输特性，并且少数组分对传输行为的模拟效果将用于指导玻璃组合物的定制以适应特定的梯度折射率和微光学应用。 研究结果将被纳入梯度透镜公司的原型透镜中，以及一家位于纽约州罗切斯特的小型高科技公司，该公司生产微光学和梯度折射率透镜。 到项目的第三年，我们将把大量的扩散参数和模型纳入商业透镜设计程序，并将设计、公差、制造和测试离子交换梯度折射率透镜系统的质量。 ***
