3D Visualization of the Flow Fields Using Digital In-Line Holography

Abstract

A digital micro-holographic system is designed for the observation of the evolution of MR fluids. The 3D distribution of micro-particles in MR fluids without magnetic field and the microstructure in MR fluids under an applied magnetic field are investigated. The change of microstructure of MR fluids under magnetic field is monitored and the responding speed of MR effect is obtained. The experimental results indicate the digital micro-holography is an efficient tool for measurement of behaviors of MR fluids.
