This award is funded under the American Recovery and Reinvestment Act of 2009(Public Law 111-5). Trends such as increasing energy costs and desire for improved functionality are driving materials and structures to be lighter, smaller, and more complex without sacrificing critical properties such as strength and endurance. Examples of these advanced technologies include: ultra-lightweight and biologically-inspired structures, advanced composite materials, micro-electro-mechanical systems, fuel cell technology, and snow engineering. In order to meet performance expectations, engineering researchers in the College of Engineering at Montana State University (MSU) must be able to explore across widely different length and time scales. The combination of the acquired ARAMIS high resolution digital imaging system and the Polytec laser vibrometer provides assessment of static and dynamic structural responses that can be connected back to material microstructure. This capability allows MSU researchers to discover new material properties and solve important problems in material/structure interaction, while simultaneously providing new opportunities for research and teaching activities. The flexibility of the acquired instruments stimulates interdisciplinary study that improves the quality and depth of research at MSU. These tools are utilized for education at the undergraduate, graduate, and post-doctoral level to illustrate fundamental concepts and new ways of engineering "seeing". MSU's strong commitment to undergraduate research through required senior research projects, summer undergraduate projects, and Native American summer research programs such as the Montana Apprenticeship Program, further expands the impact of this acquisition as educational research instruments. The capabilities of the new instruments also opens opportunities for new fields of study at MSU, as well as the discovery of new materials for basic science and technology.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。能源成本增加和对改进功能的需求等趋势正在推动材料和结构变得更轻，更小，更复杂，而不会牺牲强度和耐久性等关键性能。 这些先进技术的例子包括：超轻和生物启发的结构，先进的复合材料，微机电系统，燃料电池技术和雪地工程。 为了达到预期的性能，工程研究人员在工程学院在蒙大拿州立大学（MSU）必须能够探索广泛不同的长度和时间尺度。 ARAMIS高分辨率数字成像系统与Polytec激光测振仪的组合可评估静态和动态结构响应，并可与材料微观结构相关联。 这种能力使MSU研究人员能够发现新的材料特性，解决材料/结构相互作用中的重要问题，同时为研究和教学活动提供新的机会。所获得的仪器的灵活性刺激了跨学科研究，提高了MSU研究的质量和深度。 这些工具用于本科生，研究生和博士后水平的教育，以说明工程“看”的基本概念和新方法。 密歇根州立大学的坚定承诺，通过所需的高级研究项目，夏季本科生项目和美国本土夏季研究计划，如蒙大拿州学徒计划，本科研究，进一步扩大了本次收购的影响作为教育研究工具。新仪器的能力也为密歇根州立大学的新研究领域以及基础科学和技术的新材料的发现提供了机会。
