Abstract

We have designed a special purpose computer system for digital holographic particle tracking velocimetry (DHPTV). We present the pipeline for calculating the intensity of an object from a hologram by fast Fourier transform in an FPGA chip. This system uses four FPGA chips and can make 100 reconstructed images from a 256x256-grid hologram in 266 msec. It is expected that this system will improve the efficiency of analysis in DHPTV.

摘要

我们设计了一种用于数字全息粒子跟踪测速技术（DHPTV）的专用计算机系统。我们展示了通过在现场可编程门阵列（FPGA）芯片中进行快速傅里叶变换从全息图计算物体强度的流程。该系统使用四个FPGA芯片，能够在266毫秒内从256×256网格的全息图生成100张重建图像。预计该系统将提高DHPTV分析的效率。
