Abstract.  Results of recent experimental measurements of aero-optical distortions caused by turbulent boundary layers at subsonic speeds M=0.40.6 are presented. Measurements were performed using a high-speed Shack-Hartmann sensor to collect instantaneous wavefronts with high spatial and temporal resolution, accompanied by wavefront measurements with a Malley probe. Effects of different aperture sizes on levels of aero-optical aberrations and detailed statistical analysis of spatial and temporal spectra of aero-optical distortions for both wavefront sensors are presented and discussed.
