Inexpensive multi-plane particle image velocimetry based on defocusing: proof of concept on two-component measurement

These are the raw data of the laminar flow rig test presented in the article "Inexpensive multi-plane particle image velocimetry based on defocusing: proof of concept on two-component measurement". They include horizontal and vertical flow directions, focused and defocused images with different plane separations (in which 0mm indicates in-focus images), and different particle displacements (quantified by delta_t of the PIV image pair).

本数据集为论文《基于散焦法的低成本多平面粒子图像测速（Particle Image Velocimetry，PIV）：双分量测量的概念验证》中所呈现的层流试验台测试原始数据。数据涵盖水平与竖向来流方向、不同平面间距的聚焦与散焦图像（其中0mm代表焦平面图像），以及不同的粒子位移量（通过PIV图像对的delta_t进行量化）。如有任何疑问，请联系[e-mail]。光学引擎数据的访问详情请参阅Optical_Engine_Data_Access.txt文件。
