| Research Abstract |
We have designed a PC cluster system with special purpose computer boards for visualization of fluid flow using digital holographic particle tracking velocimetry (DHPTV).
In this board, there is a Field Programmable Gate Array (FPGA) chip in which is installed a pipeline for calculating the intensity of an object from a hologram by fast Fourier transform (FFT). This cluster system can create 1,024 reconstructed images from a 1024 × 1024 -grid hologram in 0.77 sec. Hence, the calculation speed of the FFT-HORN cluster system is about 110 times faster than that of PC.
It is expected that this system will contribute to the analysis of fluid flow using DHPTV.
