Optical measurements have been successfully performed using a high-speed Shack-Hartmann sensor to quantify a characteristic frequency of flow perturbations at different locations in the flowfield and the plasma impact on the spectrum of disturbances in the boundary layer and in the separation bubble. It was shown that the near-surface plasma, generated at a frequency of repetition higher than a dominant natural frequency of perturbations in the boundary layer (the first mode F1),...‬, lead to a significant intensification of the amplitude of the high-frequency disturbances in the range of … .The plasma effect was negligible or insignificant at excitation frequencies below F1.
