The introduction of DGV to the aerodynamics community in the early 1990’s resulted in a variety of feasibility studies to test its capabilities in wind tunnel applications. DGV held -and still holds- promise in efficiently providing high resolution maps of the velocity field. DGV has no obvious restrictions as to the size of the imaged area, nor does DGV exhibit a preferential flow sensitivity which is typical of the PIV technique. The adjustable dynamic range of DGV makes it very suited for a multitude of wind tunnel applications, especially in medium speed to supersonic flows. The text describes three examples of recent applications of DGV in transonic and supersonic wind tunnel facilities: (1) DGV in the ETW transonic cryogenic facility, (2) DGV in the T-2 facility of ONERA Toulouse, (3) DGV in a blow-down supersonic wind tunnel of ISL.
