タイトル（掲載誌）航空宇宙技術研究所報告 = Technical Report of National Aerospace Laboratory TR-516
一般注記Laser holography provides greater performance in aerodynamic testing than optical techniques previously used due to the light wave front reconstructed from the hologram containing all original density field data. This means that the reconstructed light wave can be analyzed using not only conventional procedures, but also new more advanced methods, such as time-differential interferometry. Presented in this paper are some preliminary experimental results on the application of laser holography to axisymmetric supersonic flow field observations utilizing the following methods; (1)holographic schlieren method, (2)dual holographic interferometry, (3)double exposure holographic interferometry and (4)real-time holographic interferometry. The experimental values obtained utilizing these methods on a free-jet, a sharp cone and a flat faced body are compared with conventional interferometric data and experimental and calculated pressure distributions, with good agreement being observed.
