Abstract
Micro digital holographic particle tracking velocimetry with high-speed system is constructed by PC grid environment, which is used by Windows XP with AD-POWERs as parallel tool. Two algorithms for high-speed system are evaluated under the same PC grid environment. Both methods are based on the digital hologram algorithm. The first method is a division algorithm based on the time developing for the measurements. The second is a division algorithm based on the spatial reconstruction for the measurement. In case of the former, the performance is achieved for 4.7 times using 5 PC. The utilization of present system is possible to compute the huge hologram images on-site at the experimental facility.
