介绍了用于体积粒子图像测速(PIV)的多能级二维和基于网格的三维照明系统的发展，该系统使用单个摄像机和任意数目的低功率激光。这个灵活的系统是稳健的，能够在由相机选择、镜头景深和激光功率决定的一系列时空尺度上捕捉结果。该系统是在旋转旋转实验中演示的，我们以2352×1728 像素的空间分辨率提取高保真速度场，最高可达62帧/S。这种系统提供的灵活性和经济性--大约是可比商业套餐的十分之一--可能使其对许多实验室用户具有吸引力。
We describe the development of both multilevel two-dimensional and grid-based three-dimensional illumination systems for volumetric particle image velocimetry (PIV) that uses a single camera and an arbitrary number of low powered lasers. This flexible system is robust and capable of capturing results over a range of spatiotemporal scales determined by the choice of camera, the depth of field of the lens, and the laser power. The system is demonstrated on a rotating spin-up experiment where we extract high fidelity velocity fields at up to 62 frames/s at a spatial resolution of 2352×1728 pixels. The flexibility and economy offered by this system--approximately one-tenth that of a comparable commercial package--may make it attractive to many laboratory users.
