Proposal Number: ECS-9622471 Principal Investigator: Yasuo Kuga/University of Washington Title: Research Equipment Grant: Instrumentation for Space-time Interferometry and Imaging in Composite Materials and Random Media Abstract This is a Research Equipment Grant for purchase of optical and microwave equipment which will be used for development of experimental techniques and systems for generalized space-time interferometry. This includes the time-frequency correlation for pulse, spatial interference for angular and polarization correlations, and coherent interference for backscattering. The PI's present systems are inadequate for present and future needs because of limited signal to noise ratio, unavailability of key components, and lack of modulation capability in the optical systems. The requested equipment, a general purpose wideband microwave amplifier, microwave components and an optical EO amplitude modulator, will remove these restraints and will great enhance the PI's NSF sponsored research effort in remote sensing. Especially the optical EO modulator is essential for converting the present system for space-time interferometry. Several projects will utilize the enhanced experimental capability: (i) ultrawideband scattering by random media (ii) angular polarization correlations and imaging of objects in random media (iii) enhanced backscattering and resonant location and (iv) characterization of composite materials. The equipment will also be used by several multidisciplinary research groups in collaboration with the Electromagnetic and Remote Sensing Laboratory, which has 6 faculty members and more than 20 graduate students.

提案编号：ECS-9622471 主要研究者：Yasuo Kuga/华盛顿大学 标题：研究设备补助金：复合材料和随机介质中的时空干涉测量和成像仪器 摘要 这是一项研究设备赠款，用于购买光学和微波设备，这些设备将用于开发广义时空干涉测量的实验技术和系统。这包括脉冲的时间-频率相关性，角度和偏振相关性的空间干涉，以及后向散射的相干干涉。 PI的现有系统不足以满足当前和未来的需求，因为有限的信噪比，关键部件的不可用性，以及光学系统中调制能力的缺乏。所要求的设备，一个通用的宽带微波放大器，微波组件和光学EO幅度调制器，将消除这些限制，并将大大提高PI的NSF赞助的遥感研究工作。 特别是光学电光调制器是将现有系统转换为空时干涉测量所必需的。 几个项目将利用增强的实验能力：㈠随机介质的超宽带散射; ㈡随机介质中物体的角偏振相关性和成像; ㈢增强的后向散射和共振定位; ㈣复合材料的表征。 该设备还将由几个多学科研究小组与电磁和遥感实验室合作使用，该实验室有6名教职员工和20多名研究生。
