Abstract
The two wavelengths multi-exposure method is applied for the study of vortices generated by the interaction between a swell and an immerged plate. However, in such flows, the range of velocities to be measured is large. Here, we show that a combination of several pulse sequences enables to achieve velocity measurements both in the core and in the periphery of the vortex.
