摘要

粒子图像测速(PIV)在不干扰流动的情况下测量二维平面内的流动矢量。悬浮颗粒的多次曝光照片被用来给出流速矢量。由于显影过程的原因，PIV不能实时测量。为了实时处理，我们提出了一种使用液晶显示器的空间滤波技术的光学PIV系统。

Real time particle image velocimetry using liquid crystal display

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.<>
