Colored grid background oriented schlieren (CGBOS) technique was applied to the super sonic flow field around asymmetric body. The experiments were carried out in the 0.6 m × 0.6 m test section of supersonic wind tunnel at JAXA-ISAS. Three-dimensional density information also obtained quantitatively with CT (Computed Tomography) technique.
