| Outline of Final Research Achievements |
Recently, three-dimensional flow visualization and measurement are required in various fields. Digital holography is used in these studies. Digital holography is a technology that applies digital technology to holography, which is a three-dimensional display technology. There are many effective points such as being able to obtain three-dimensional information by shooting from one direction and being able to perform processing in a computer. However it has not been put into practical use because it takes time to process in a computer. We have developed a special purpose computer system using FPGA. By implementing multiple calculation pipelines in the FPGA for processing holograms in parallel in the depth direction, we succeeded in constructing a faster computer system than a PC.

| Academic Significance and Societal Importance of the Research Achievements |
ホログラフィを用いた三次元流体速度場可視化システムで光学系を用いて撮影したホログラムには対象となる流体中の粒子の三次元情報が含まれている．このホログラムから流体中のマーカの位置を再生し，解析を行うことで流体の三次元速度場の情報を得ることが出来る．ディジタルホログラフィー技術は，微小な液滴・粒子・気泡群などの時間変化を三次元空間計測するのに適しており，空間位置計測，移動量（速度）計測，数密度計測，粒径等計測，形状・姿勢計測，高速度物体のイメージングなど今後工学的な応用範囲も一層広がりを見せるものと期待される．そのため，ホログラムの処理を高速化できる専用計算機システムは非常に有用であると思われる．
