A polychromatic flow visualization technique for Particle Streak Velocimetry (PSV) is described. The method uses several adjoining laser light sheets of different wavelengths with a homogeneous power density distribution. This method allows us to make sure of the 2-D and 3-D nature of flows and to improve the frames quality processed in PSV. The feasibility study of this qualitative technique is established on a hydrodynamic flow. [S0098-2202(00)02402-0]
