A one-component Doppler Global Velocimeter has been designed and tested in an empty wind tunnel generating a perfectly calibrated flow. Most of the technical choices involving light sheet generation, optical components, cameras, iodine cell, are described and argued, as well as geometrical calibration and processing steps. A specific device has been developed, but not yet described, to relax constraints on the stabilization of laser frequency and iodine cell temperature. Velocity maps obtained by this D.G.V. system are compared to the known Mach number. These promising results show the interest of following such a procedure to qualify and optimize a prototype.
