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.
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技术（DHPTV）来可视化流体流动。该计算机包含一个现场可编程门阵列（FPGA）芯片，其中安装了一个通过快速傅里叶变换从全息图计算物体强度的流水线。该系统可以在3.3秒内从1024×1024网格的全息图中生成100张重建图像。预计该系统将有助于流体流动分析。
