We describe a non-intrusive PIV system developed for performing high-r
esolution measurements in a field of view of 2 m x 3 m, as required on
the LEGI-Coriolis 13 m diameter rotating platform. Particle preparati
on, laser illumination, photographic digitization, and cross-correlati
on analysis techniques are explained. Some results on the wake behind
a cylinder illustrate the possibilities of this PIV system.
