ABSTRACT The Department of mechanical Engineering at Kansas State University (KSU) will acquire and upgrade equipment for development of Holographic Particle Image Velocimetry (HPIV). A Laser Flow Diagnostics Laboratory, with its primary goal being the development and application of HPIV, has been set up in the Department. The upgrade will enable off-axis HPIV and the establishment of a suitable data processing system. The upgrade consists of adding injection seeding and an improved transverse-mode option to the existing pulsed laser to convert it to a highly coherent laser that can record holograms of three-dimensional particle fields, matching the wavelength of the hologram reconstruction laser to that of the recording laser, and setting up an open-architecture heterogeneous optical-digital data processing system. The establishment of HPIV will bring the capability of providing instantaneous high-resolution three-dimensional (3D) flou velocity field data. Its establishment will contribute to our understanding, modeling and controlling of turbulent and complex flows which are of fundamental and technological importance.

摘要 堪萨斯州立大学（KSU）的机械工程系将获得并升级用于开发全息粒子图像测速仪（HPIV）的设备。该部门建立了一个激光流动诊断实验室，其主要目标是开发和应用HPIV。升级后将能够进行离轴HPIV并建立适当的数据处理系统。升级包括在现有的脉冲激光器上增加注入种子和改进的横模选项，将其转换为可以记录三维粒子场全息图的高度相干激光器，将全息图重建激光器的波长与记录激光器的波长相匹配，并建立一个开放式结构的异构光学数字数据处理系统。HPIV的建立将带来提供瞬时高分辨率三维流场数据的能力。它的建立将有助于我们对湍流和复杂流动的理解、建模和控制，这具有重要的基础和技术意义。
