INTRODUCTION
What all these methods have in common is the existence of a tracer whose movement is observed from the light it emits or scatters. We can distinguish between parietal methods, in which tracers are placed on the wall of a model, and those in which they are injected into the heart of the fluid. We can also distinguish between traditional methods, in which illumination is provided by an incoherent light source (usually white), and tomographic methods, which use coherent laser light. In all cases, the movement of the tracers is assumed to be representative of the flow under study.
