一种用迈克尔逊干涉法拍摄“多普勒图像”的方法，发展了一种在整个平面上显示速度场的技术。通过多普勒图像测速（DPV），可以获得有关示踪剂穿过光片的瞬时和局部速度的信息。Doppler图象的拍摄和处理技术最近已得到改进，本文将介绍DPV方法的最新技术，并将其应用于高速流体流动，显示在ISL高能激波风洞STB中产生的穿过超声速楔形流的光片平面中的速度分布。与粒子图像测速（PIV）速度可视化的比较。
AbractA technique for visualizing a velocity field in an entire plane has been developed by taking ‘Doppler Pictures’ using Michelson interferometry. With the Doppler Picture Velocimetry (DPV), information about the instantaneous and local velocities of tracers passing through a light sheet is available. The technique for taking and processing the Doppler pictures has been improved recently and the state-of-the-art of the DPV method will be described with an application in high-speed fluid flows showing the velocity distribution in a light sheet plane crossing a supersonic wedge flow generated in the high-energy shock tunnel STB of ISL. A comparison with Particle Image Velocimetry (PIV) velocity visualizations is also presented.
