激光粒子图像速度场仪的开发

The development of laser particle image velocimetry(LPIV)system

:激光粒子图像速度场仪 (LPIV)是近年发展起来的一种流速测量新技术。本文开发了一套激光粒子图像速度场仪系统 ,其中包括成像及查询系统两大部分的开发。该系统利用灰度判别法来判别粒子图像的运动方向。

Laser Particle Image Velocimetry (LPIV) is a new technique of flow velocity measurement which is developed recently.This paper develops a set of PIV system,which includes image system and interrogation system.By means of the greyness determinant method the paper determines the direction of particle image motion.Practices testify that the development is successful.
