This paper provides an overview of recent wind tunnel tests performed at the NASA Langley Research Center where the Background-Oriented Schlieren (BOS) technique was used to provide information pertaining to flow-field density disturbances. The facilities where the BOS technique was applied included the National Transonic Facility (NTF), Transonic Dynamics Tunnel (TDT), 31-Inch mach 10 air tunnel, 15-Inch mach 6 high-temperature air tunnel, rotor test cell at the 14×22 subsonic tunnel, and a 13-Inch low-speed tunnel.
