Real time particle image velocimetry using liquid crystal display

Abstract

Particle Image Velocimetry (PIV) measures two-dimensional in-plane flow vectors without disturbing the flow. The multiple exposure photo of the particles suspended into the flow has been used to give the flow velocity vector. Because of the photo developing process, the PIV has not measured in real-time. To process in real-time, we propose an optical PIV system of the spatial filtering technique using a Liquid Crystal Display.<>
