抄録

Background-oriented schlieren (BOS) system proposed in this paper realizes high-spatial resolution by applying the single-pixel correlation method for the image pairs obtained in the process of BOS. The backgrounds are projected by a high-speed projector and changed at 900 Hz for calculation of the pixel-to-pixel correlation. The proposed method is compared with the conventional method which utilizes the constant background and the conventional spatial correlation. The results show that the proposed system enables to obtain the higher-resolution displacement distribution than conventional one.
