Definition

Most of the microfluidic systems have prominent three-dimensional effects due to the complexity in the channel geometry and wall effects. The flow characterization of these systems demands appropriate diagnostic techniques. Traditionally, micro-PIV and confocal-PIV systems are used for the measurement of three-dimensional flow field in microsystems. However, these techniques are expensive and do not provide complete 3D velocity field at any specific time instants. Micro-holographic PIV/PTV is another potential alternative technique, which offers superior capabilities with lesser cost. This entry reviews this technique for application in microfluidic systems.

Overview

Holography is an optical technique based on combined interference and diffraction phenomenon, which provides three-dimensional information about the object field of interest. It is carried out in two steps, i.e., hologram recording and object...
