In previous works, 3D-CT reconstruction of instantaneous light emission distributions of turbulent premixed flames, and time-series 3D-CT distributions have been successfully obtained. However, for high speed detection of flames, the images were blurry due to low quantity of light. In present study, for 3D observation of high speed turbulent flames, non-scanning 3D-CT technique using a multi-directional quantitative schlieren system with flash light source is proposed for instantaneous density distribution of unsteady premixed flames. In this paper, with a 20 directional schlieren camera, instantaneous density distributions of a high speed turbulent flame, which can be used as an industrial furnace burner flame, have been CT-reconstructed.
