The velocity field of fluid flow can be obtained by using either particle tracking velocimetry (PTV) or particle image velocimetry (PIV) approach. The PTV approach is most suitable when the particle concentration in the fluid is low. The PIV approach is used when the particle concentration is high. It is primarily based on the cross correlation between images acquired at two different time instances. Because digital holography...

PIV is an optical whole-field, nonintrusive measurement technique to measure fluid velocity by recording the displacement of small tracer particles added to the fluid. PIV has been extensively reviewed in the past [5] and can be divided into pattern-matching velocimetry (PMV) and particle-tracking velocimetry (PTV). PIV offers more flow information per interrogation, and thus substantially, more work has been done in this field compared to LDV and ODT.

To elucidate the shear-banding scenario in wornolike micelles, different velocimetry techniques with high spatial resolution, typically between 10 and 50 pm, such as nuclear magnetic resonance (NMR) velocimetry, particle image velocimetry (PIV), particle tracking velocimetry (PTV), photon correlation spectroscopy (DLS), and ultrasonic velocimetry (USV) have been developed. All provide the velocity component along the flow direction taken from a one-dimensional slice across the gap. For details on these techniques, the reader is invited to refer to [245,246].
