The method for visualizing three-dimensional shock shapes by using electrical discharges has been developed in this paper. The improved method can visualize wide field shock shapes around hypersonic vehicles by using a single electrical discharge. In order to improve the method, a wide and flat electrical discharge shape was considered. To generate such an electrical discharge shape, a pair of point-line electrodes were utilized. Moreover, in the case of the visualization of shock shapes utilizing the pair of point-line electrodes, it was proved that the electric current should be as small as possible.
