PROPOSAL NO.: CTS-0502421PRINCIPAL INVESTIGATOR: VOLKAN OTUGENINSTITUTION: POLYTECHNIC UNIVERSITY OF NYSGER: A Micro-Optical Wall Shear Stress Sensor Based on Whispering Gallery Mode ResonatorsThis grant is to develop a novel micro-optical wall shear stress sensor based on dielectric micro-beads that are excited by coupling light from optical fibers. The technology exploits the morphology-dependent shifts in resonant frequencies that are commonly referred to as the whispering gallery modes (WGM). A minute change in the size, shape or optical constants of the micro-bead causes a shift in the resonant frequency (or the WGM). This optical phenomenon is the harbinger of a new class micro-sensors that can be used for a wide range of fluid dynamic applications; any physical stimuli that can directly or indirectly change the size, shape or optical constants can be detected with higher resolution than can be realized by existing mechanical sensors. Furthermore, the concept can be easily extended to a system of distributed micro-sensors providing spatial data resolved in time and space. With the growth of wide-band communications through optical fibers, the use of WGMs of miniature optical elements are rapidly becoming commonplace in the telecommunication industry where components that are several wavelengths of light in size are used. However, such components are seldom manipulated mechanically to develop new sensor technologies. The intellectual merit of this work is its contributions to the development of a novel sensor. The proposed research will explore a new concept for micro-optical wall shear stress sensors that is based on the WGMs of dielectric resonators and that exploits recent technological developments in the telecommunications field. The broader impacts of this work will include advancing discovery and understanding while promoting teaching and learning, broadening the participation of underrepresented groups, and broad dissemination of results for the enhancement of scientific and technical understanding. Although the primary area of application for the proposed sensor is fluid mechanics research, the proposed activity will have the following broader impact: the micro-optical wall shear sensor can have a significant impact on process control in manufacturing industries as well as the medical field. Furthermore, the successful completion of this effort will lay the groundwork for the development of a much broader range of WGM-based sensors for temperature, pressure and species concentration. Therefore, although several technical challenges exist in the development of rugged, reliable optical sensors of this kind, the payoff at the successful conclusion are very significant. Polytechnic's Youth in Engineering and Science (YES) program, will provides opportunities for high school students (juniors and seniors) to participate in this research project and to receive exposure to science and engineering.

建议没有。项目名称：cnt -0502421项目负责人：VOLKAN otugenn机构：纽约理工大学：一种基于低语廊模式谐振器的微光壁剪应力传感器本项目资助的目的是开发一种基于介电微珠的新型微光壁剪应力传感器，该传感器由光纤耦合光激发。该技术利用谐振频率的形态相关位移，通常称为窃窃私语廊模式（WGM）。微珠的大小、形状或光学常数的微小变化都会引起谐振频率（或WGM）的变化。这种光学现象是一种新型微传感器的先兆，可用于广泛的流体动力学应用；任何可以直接或间接改变尺寸、形状或光学常数的物理刺激都可以用比现有机械传感器更高的分辨率进行检测。此外，该概念可以很容易地扩展到分布式微传感器系统，提供在时间和空间上解决的空间数据。随着通过光纤进行宽带通信的发展，微型光学元件wgm的使用在电信行业中迅速普及，其中使用的组件尺寸为几个波长的光。然而，这些部件很少被机械地操纵来开发新的传感器技术。这项工作的智力价值在于它对开发一种新型传感器的贡献。提出的研究将探索一种基于介电谐振器wgm的微光学壁剪应力传感器的新概念，并利用电信领域的最新技术发展。这项工作的更广泛影响将包括在促进教与学的同时促进发现和理解，扩大代表性不足群体的参与，以及广泛传播成果以增进科学和技术理解。虽然所提出的传感器的主要应用领域是流体力学研究，但所提出的活动将产生以下更广泛的影响：微光学壁剪切传感器可以对制造业和医疗领域的过程控制产生重大影响。此外，这项工作的成功完成将为开发更广泛的基于wgm的温度、压力和物种浓度传感器奠定基础。因此，尽管在开发这种坚固可靠的光学传感器方面存在一些技术挑战，但成功的回报是非常显著的。理工学院的青年工程与科学（YES）计划将为高中生（三年级和四年级）提供参与该研究项目并接触科学和工程的机会。
