我们设计了一种专用计算机系统，用于使用数字全息粒子跟踪测速 (DHPTV) 来可视化流体流动。该计算机包含现场可编程门阵列（FPGA）芯片，其中安装了用于通过快速傅里叶变换从全息图计算物体强度的管道。该系统可以在 3.3 秒内从 1024 x 1024 网格全息图生成 100 个重建图像。预计该系统将有助于流体流动分析。 (C) 2008 年美国光学学会。
We have designed a special purpose computer system for visualizing fluid flow using digital holographic particle tracking velocimetry (DHPTV). This computer contains an Field Programmble Gate Array (FPGA) chip in which a pipeline for calculating the intensity of an object from a hologram by fast Fourier transform is installed. This system can produce 100 reconstructed images from a 1024 x 1024-grid hologram in 3.3 sec. It is expected that this system will contribute to fluid flow analysis.
