The reliable measurement of the 3D3C velocity field in microfluidic devices becomes more
and more important for future optimization and developments for lab-on-a-chip applications …

This chapter reviews the different techniques that have been proposed in the last few years
for turning PIV into a 3D velocimetry technique. Any technique capable of simultaneously …

We have used a digital in-line holography system with numerical reconstruction for 3D
particle field extraction. In this system the diffraction patterns (holograms) are directly …

Multi-camera flow diagnostics have made large gains in recent years in the field of three-
dimensional and multi-physics measurements. However, cost, complexity and optical access …

Recent developments have shown the potential of digital in-line holography for diagnostics
in fluids. This new method provides a low-cost and easy access method for measuring both …

Holographic particle image velocimetry allows tracking particle trajectories in time and
space by means of holography. However, the drawback of the technique is that in the three …

Abstract An extended Generalized Fresnel Transform (GFT) is proposed to account for the
astigmatism introduced by optical elements described, in the paraxial approximation, with a …

The potential of in-line digital holography to locate and measure the size of particles
distributed throughout a volume (in one shot) has been established. These measurements …

A direct application of digital in-line holography to liquid droplets dispersed in a continuous
liquid phase is described. The droplet size imposes a regime of intermediate-field diffraction …

Digital in-line holography is used to visualize particle motion within a cylindrical micropipe.
Analytical expression of the intensity distribution recorded in the CCD sensor plane is …
