对国际聚变材料辐照装置（IFMIF）的锂靶进行了锂流实验。在实验中，用双收缩喷嘴形成了深10 mm、宽70 mm的Li平面射流，射流速度小于15 m/s。在本报告中，波型（称为表面尾迹）上的Li流测量图案投影方法。这是一种非接触的三维图像测量。观察到投影图案（在本研究中为条纹）根据表面上下变形。通过分析变形后的图案，可以得到三维表面形状。利用该方法成功地测量了表面尾迹。与理论研究的结果进行了比较，并表现出良好的一致性。
Lithium (Li) flow experiment was conducted for a Li target of International Fusion Materials Irradiation Facility (IFMIF). In the experiment, Li plane jet of 10mm in depth and 70mm in width formed by a two contractions nozzle was tested in the velocity range of less than 15m/s. In the present report, wave patterns (called as surface wakes) on the Li flow were measured by Pattern Projection Method. This is an image measurement of non-contact and three dimensions. The projected patterns, which were stripes in this study, were observed to be deformed according to the surface up-and-down. Three-dimensional surface shape could be obtained by analyzing the deformed patterns. By the method, surface wakes were successfully measured. The results were compared with a theoretical study and showed good agreement.
