项目摘要
MRI: Acquisition of High-Speed Cameras with Quantitative Stereo Imaging and Digital Image Correlation Capabilities for Multidisciplinary Research and EducationAbstractVisualization and imaging are important aspects in the processes of discovering and understanding new phenomena. Because of recent advances in imaging technologies and related hardware and software, improved capabilities to perceive and measure three-dimensional events at high-speeds allow for investigating various phenomena at a more detailed level than ever before. Furthermore, as new materials, devices, and systems move beyond the exploration stage and relatively simple configurations to more complex ones, high-resolution analysis and testing become critical issues and particularly to those involving both, spatial and temporal domains. These state-of-the-art imaging instruments will provide new capabilities for three-dimensional imaging of a variety of collaborative and multidisciplinary projects spanning from testing materials and systems at the meso- and micro-scale to biomedical, manufacturing, and energy applications. These high-speed cameras with quantitative digital image correlation will facilitate the complete three-dimensional investigation of transient events with unprecedented spatial and temporal resolutions. Examples of the use of these high-speed cameras at Worcester Polytechnic Institute will include a- high-resolution acoustic-solid interactions and micro-/nano-systems; b- measurement of bubble departure diameter rand frequency under extreme heat fluxes for electrically driven liquid film flow boiling over surfaces enhanced with nano-mats; c- capturing both instantaneous damage initiation events (occurring at micro-/nano-structural features such as secondary phases/metal matrix interfaces, grain/phase boundaries, defects, etc.), as well as crack propagation phenomena at various growth rates; d- investigating the structure and turbulent mixing processes of dust-air flames; and e- understanding of MRI-guided deep brain surgery through quantitative assessment and optimization of motion of the piezo crystals and surrounding tissue.
摘要在发现和理解新现象的过程中,可视化和成像是重要的方面。由于成像技术和相关硬件和软件的最新进展,高速感知和测量三维事件的能力得到了提高,因此可以在比以往任何时候都更详细的水平上调查各种现象。此外,随着新材料、设备和系统从探索阶段和相对简单的配置走向更复杂的配置,高分辨率分析和测试成为关键问题,特别是涉及空间和时间域的问题。这些最先进的成像仪器将为各种合作和多学科项目的三维成像提供新的能力,从中尺度和微观尺度的测试材料和系统到生物医学、制造和能源应用。这些具有定量数字图像相关的高速摄像机将以前所未有的空间和时间分辨率促进瞬态事件的完整三维研究。在伍斯特理工学院使用这些高速摄像机的例子将包括高分辨率声-固相互作用和微/纳米系统;在纳米垫增强表面上沸腾的电驱动液膜流在极端热流下气泡偏离直径和频率的测量;C -捕捉瞬时损伤起始事件(发生在微/纳米结构特征处,如二次相/金属基体界面、晶粒/相边界、缺陷等),以及不同生长速率下的裂纹扩展现象;D -研究粉尘-空气火焰的结构和湍流混合过程;以及通过定量评估和优化压电晶体和周围组织的运动来理解mri引导的深部脑手术。
