研制了第一代全自动三维粒子跟踪测速仪。它通过对尼龙颗粒散射的光进行成像来测量流体的速度（同时测量所有3个分量），尼龙颗粒随流动而移动。图像以视频速率被捕获到两个SIT相机中。摄像机处于正交位置，并讨论了从这两个2-D投影重建3-D速度信息所需的计算算法。本文给出了一个应用该技术测量发动机节流体组件透明模型（3 × 3 × 3cm试验段）中的气相流（速度为1.65m/s）的实例。
A first generation automated 3-d particle tracking velocimeter was constructed. It measures the velocity (all 3 components simultaneously) of the fluid by imaging the light scattered from nylon particles, which move with the flow. The images are captured into two SIT cameras at video rates. The cameras are to orthogonal positions and the computational algorithms necessary to reconstruct the 3-d velocity information from these two 2-d projections are discussed. An example of the application of the technique to the gas-phase flow (≅ 6.5 m/s) through a transparent model of an engine throttle-body assembly (3 × 3 × 3 cm test section) is presented.
