4 Laser Induced Fluorescence (LIF) and Scattering Methods (Lorenz-Mie, Rayleigh, Raman) 

This approach, although complex in its implementation, is relatively straightforward and holds promise for further development. Since the technique relies on a scalar measurement in a liquid flow field, it is currently restricted to very fine scale measurements because of the large Schmidt number involved with dye flow markers in liquids. Thus, as demonstrated so far the method is over
