In the last few years particle image velocimetry (PIV) has become one of the most useful techniques for the study of flowfields. In 2D applications, it allows the simultaneous measurement of the velocity distribution on the whole acquisition area. We propose a relatively new practical PIV measurement system based on flashed lamps as light sources and digital reconstruction of particle positions by image processing. Three different colors are used in order to distinguish, on the same photograph, the corresponding positions of each moving particle at three different instants of time. This solution can give significant advantages in several aerodynamic and hydrodynamic situations. In particular, it allows high flexibility for velocity measurements and independent setting of different acquisition parameters, like pulse powers and timing. Furthermore, the developed PIV measurement system is fully transportable, eye-safe, practical, and economical.
