Abstract :
We introduce the high performance computing of Digital Holographic PTV. The algorithm is used in (1) the reconstruction of particle by digital hologram for parallel computing and (2) the reconstruction of particle by digital hologram for FPGA and (3) the reconstruction of particle by digital hologram for grid computing. The numerical reconstruction from the digital hologram makes use of the Fresnel diffraction and the FFT. The visualization measurement for micro-flow are shown by these algorithms.
