The microscope as we know it today has become an indispensable tool across many fields of research. Since the first incarnations of the microscope began to see use in research in the mid 1600’s, it has exponentially expanded the sphere of physical phenomena that can be inspected and measured, opening up a staggering number of new areas for researchers to explore and allowing them to better understand and quantify our world. Among these impacts was the discovery of micro-organisms vastly expanding our understanding of the mysteries behind everything from food spoilage to wine making to medicine and antibiotics. While it is hard to match this success, recent advancements in ultrahigh-speed cameras provides a similar opportunity for researchers to see and measure dynamic events at high resolutions never before possible. The requested ultrahigh-speed camera is capable of filming events in full HD at up to 20,000 frames per second; 150 times faster than conventional cameras. At standard definition (SD), the camera can film at an incredible 200,000 frames per second, over 1500 faster than conventional cameras, and able to capture up to 3 seconds of footage. These cameras have seen major advances in recent years thanks to steps forward in CPU and solid-state storage technologies, and can now capture highly detailed images at extreme speeds - they are truly a substantial step forward from what was available just 3 years ago in high speed videography. Further, an ultrahigh-speed camera is an extremely flexible piece of equipment which can be set-up appropriately for a very wide range of applications in only a few minutes allowing it to be shared effectively across a diverse group of researchers, thus maximizing utilization. This advanced capability will allow the PI and co-applicants to film and interact with highly dynamic events to gain an improved understanding of the physics driving important phenomena, from Dr. Wael El-Dakhakhni’s investigation of blast and high-speed impact deformation of masonry, concrete and steels, to Dr. Chan Ching, Dr. Mohamed Hamed, and Dr. Ravi Selvaganapathy’s’ investigations into dynamics of fluids and heat transfer, to Dr. Philip Koshy and Dr. Stephen Veldhuis’s applications in advanced manufacturing research aimed at improving understanding of manufacturing processes. In each case improvements in understanding drive fundamental research, promote highly engaged learning and provide data vital to supporting our interaction with our industrial and research partners.

我们今天所知道的显微镜已经成为许多研究领域不可或缺的工具。自从17世纪中期显微镜的第一个化身开始在研究中使用以来，它以指数方式扩展了可以检查和测量的物理现象的范围，为研究人员探索开辟了惊人数量的新领域，并使他们能够更好地理解和量化我们的世界。这些影响之一是微生物的发现极大地扩展了我们对从食物腐败到酿酒到药物和抗生素等一切事物背后奥秘的理解。虽然很难与这一成功相提并论，但超高速相机的最新进展为研究人员提供了类似的机会，可以以前所未有的高分辨率观察和测量动态事件。 所要求的超高速摄像机能够以每秒20，000帧的速度拍摄全高清事件;比传统摄像机快150倍。在标准清晰度（SD）下，相机可以以令人难以置信的每秒200，000帧的速度拍摄，比传统相机快1500多帧，并且能够捕获长达3秒的镜头。近年来，由于CPU和固态存储技术的进步，这些相机取得了重大进展，现在可以以极高的速度捕捉高度详细的图像-它们比3年前的高速摄像技术迈出了实质性的一步。此外，超高速摄像机是一种非常灵活的设备，可以在几分钟内为非常广泛的应用进行适当的设置，使其能够在不同的研究人员中有效地共享，从而最大限度地利用。 这种先进的能力将使PI和共同申请人能够拍摄高度动态的事件并与之互动，以更好地了解驱动重要现象的物理学，从Wael El-Dakhakhni博士对爆炸和高速冲击变形的研究，到Chan Ching博士，Mohamed Hamed博士和Ravi Selvaganapathy博士对流体动力学和传热的研究，Philip Koshy博士和Stephen Veldhuis博士在先进制造研究中的应用，旨在提高对制造过程的理解。在每一种情况下，理解的改善都会推动基础研究，促进高度参与的学习，并提供支持我们与工业和研究合作伙伴互动的重要数据。
