Acquisition of a high-speed digital imaging system for time-resolved measurements of short duration events

美国国家科学基金会主要研究仪器资助了一个基于最新技术发展的多功能成像系统。研究仪器包括(a)一个非常通用的，高分辨率，图像增强帧/条纹CCD相机，(b)一个全固态相干，准直和单色激光光源，与高速相机一起操作，以及(c)一个宽带，高采样率数字示波器，用于各种基于激光干涉测量的光学技术。该系统代表了机械和航空航天工程系几个主要实验室的激光诊断能力的基本升级，并将支持Case工程学院的其他研究和开发。新的超快速成像系统的先进功能将被PI、两名副PI和Case工程学院的其他几名贡献教员利用，在实验技术重要领域进行基础实验研究。拟议的设备预计将大大鼓励大学内部和大学之间的合作。在凯斯西储大学，高速成像系统的收购将汇集大分子科学、材料科学与工程、机械与航空航天工程以及土木与环境工程方面的人才和设备。这些跨学科的合作研究将充分探索不同材料之间的高速摩擦现象，新型耐损伤轻型多功能材料系统的设计和开发，燃烧和爆炸科学的基础，MEMS器件的可靠性，损伤演变和失效在生物骨骼组织中的重要性，创伤生物力学和骨科。变形加工的基本原理与应用到高速率制造，仅举几例。除了对研究和发展有用外，新的高速数字成像系统将为研究生和研究生提供实验室经验和培训现代仪器技术的机会。除了拟议项目领域内的基本科学内容外，该培训还涉及应用技术领域，这些领域由拟议研究中的元素所连接，这些元素在为短时间事件的先进激光诊断开发仪器和新实验方法方面寻找积极的机会。这样做的一个结果是培养出能够将实验和分析技术结合起来，在技术上重要的领域进行研究的工程师。CWRU凯斯工程学院强烈鼓励本科生参与教师的研究项目，这也将发生在拟议的工作中。将尽一切努力鼓励和吸引本科生和研究生，特别是来自目前在工程学科中代表性不足的群体的学生。

The NSF Major Research Instrumentation grant funds a versatile imaging system based on new developments in the state of the art technology. The research instrumentation comprises (a) an extremely versatile, high resolution, image intensified framing/streak CCD camera, (b) an all-solid state coherent, collimated and monochromatic laser light source to be operated in conjunction with the high-speed camera, and (c) a wide bandwidth, high sampling rate digital oscilloscope for use in various laser interferometry based optical techniques. The system represents a fundamental upgrade of the laser based diagnostic capabilities of several major laboratories in the Department of Mechanical and Aerospace Engineering and would support other research and development in the Case School of Engineering. The advanced capabilities of the new ultra-fast imaging system will be utilized by the PI, two Co-PI's and several other contributing faculty members of the Case School of Engineering for conducting fundamental experimental investigations in areas of importance to experimental techniques. The proposed equipment is expected to significantly encourage intra- and inter- university collaborations. At Case Western Reserve University the acquisition of the high speed imaging system will bring together talents and facilities in the Macromolecular Science, Materials Science and Engineering, Mechanical and Aerospace Engineering, and Civil and Environmental Engineering. These collaborative, multidisciplinary research efforts will explore fully the phenomena of high-speed friction between dissimilar materials, design and development of novel damage-tolerant light-weight multifunctional material systems, fundamentals of combustion and explosion science, reliability of MEMS devices, damage evolution and failure in bio-skeletal tissues of importance to trauma-biomechanics and orthopaedics, fundamentals of deformation processing with applications to high rate manufacturing, to name a few.Besides being useful on research and development, the new high-speed digital imaging system will provide an opportunity for laboratory experience and training for graduate and post-graduate students in the state-of-the-art of modern instrumentation. In addition to the basic scientific content within the proposed project areas, this training reaches into areas of applied technology that are bridged by elements within the proposed research that look for active opportunities in the development of instrumentation and novel experimental methods for advanced laser diagnostics of short duration events. One outcome of this would be the development of engineers who can integrate experimental and analytical techniques to attack technologically important areas. The Case School of Engineering at CWRU is strongly encouraging the involvement of undergraduate students in faculty research projects and this would occur for the proposed work as well. Every effort will be made to encourage and involve undergraduate and graduate students especially from groups presently under-represented in the engineering discipline.
