This proposal aims to acquire a High-Speed Volumetric Particle Tracking Velocimetric (VTPV) system capable of tracking the three-dimensional position of multiple particles within a measurement fluid volume, and subsequent calculation of velocity, or acceleration of the particles. Active research projects that would benefit from the instrument range from blood pumps to miniature medical devices to microplastics transport in the environment. The list of active research projects is expected to grow with new opportunities and collaborations. The proposed system will improve Rochester Institute of Technology’s ability to conduct leading-edge research by enhancing the infrastructure for research and education. Specifically, planned research and training at Rochester Institute of Technology and the region includes (1) student training and research, (2) two new multidisciplinary courses, and (3) training workshops. The proposed VTPV instrument is comprised of high intensity laser illumination, a set of digital cameras, and specialized optics that are integrated with dedicated synchronization hardware and image processing software. Each of the five projects described has previously benefitted from acquisition of two-dimensional fluid or particle data with the existing outdated 2D measurement system. The new data to be acquired by the proposed three-dimensional high-speed system will increase quantitative understanding of underlying flow physics, and in some cases, providing the first ever quantitative data relevant for the application.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该提案旨在获得一种能够跟踪测量流体体积内多个粒子的三维位置的高速体积粒子跟踪测速（VTPV）系统，并对粒子的速度或加速度进行后续计算。受益于该仪器的项目范围包括从血泵到微型医疗设备，再到环境中的微塑料运输。随着新的机会和合作，活跃的研究项目清单将不断增加。拟议的系统将提高罗彻斯特理工学院的开展能力。前沿研究具体来说，罗切斯特理工学院和该地区计划的研究和培训包括（1）学生培训和研究，（2）两个新的多学科课程，以及（3）拟议的 VTPV 培训研讨会。该仪器由高强度激光照明、一组数码相机和与专用同步硬件和图像处理软件集成的专用光学器件组成，所描述的五个项目中的每一个项目都曾受益于二维流体或颗粒数据的采集。现有过时的二维测量所提议的三维高速系统获取的新数据将增加对定量基础流动物理的理解，并在某些情况下，提供与应用相关的第一个定量数据。该奖项的法定使命是通过使用基金会的智力优点和更广泛的影响审查标准进行评估，认为值得支持。
