Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency(JAXA)(ISAS)), Sagamihara, Kanagawa Japan, The background oriented schlieren (BOS) technique is a novel technique that enables quantitative measurement of density change in the flow field. In this paper an approach to solve the problem of BOS technique is discussed. The problem is image blur near the model caused by focus gap. To improve the focus gap, the experiment using BOS technique with concave mirror is carried out. The visualization object is the M=2.0 supersonic flow field around an asymmetric ellipse cone model at Mach number 2.0., 資料番号: AA0065106021}, publisher = {宇宙航空研究開発機構宇宙科学研究所, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {凹面鏡系を用いたBOS法による非対称物体周り超音速流れの定量画像計測}, year = {2011} }
