摘要：
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 256 x 256-grid hologram in 266 msec. It is expected that this system will improve the efficiency of analysis in DHPTV.
