Abstract

We have developed a simple digital holographic PIV system for 3D measurement of turbulent and multiphase flow. This system records in-line holograms of tracer particles directly on a digital camera and reconstructs the 3D particle field numerically. Using a novel complex amplitude-based method, we are able to overcome the depth of focus problem and the speckle noise problem associated with the low resolution of digital sensors and the in-line holographic setup. In this paper we will give detailed description of our system, and present the preliminary result of the benchmark experiment using a water jet.
