This research describes an experimental study on the density gradient by applying the Background Oriented Schlieren technique with the physics-based optical flow using a simple setup. The design of the BOS setup primarily consists of a background which has random dots, and a high-speed camera focused on the dots. Variation of the density between the undisturbed image and the disturbed image led to a shift of the dots, which is used to generate displacement field by using the optical flow method. In addition: different pressure conditions were applied, to provide distinct displacement fields. Finally, the density gradient of flow was visualized by BOS measurements based optical flow.
