| Abstract: | A device for simultaneously measuring the three orthogonal components of a velocity vector is described. The system uses a laser beam passing twice through the region of flow under investigation. This allows one to determine the third component using only forward scattering. Vector diagrams which explain the mode of operation and experimental signals are given. |
