The high-speed camera was used for the interferometry visualization of the airflow in different phases of the profile motion. Special care was devoted to the plotting of the fringes near the surface of the profile, which was blurry due to the fast vibration. Examples of the interferograms, pressure and velocity development around the surface of the vibrating body and the phase shift between rotation and translation cycles are presented.
