An extensive investigation of the aberrating character of flow over a hemisphere-on-cylinder turret with a flat window was performed. Optical distortions over the window were measured using a two-dimensional wave front sensor and a Malley probe. The Malley probe measurements were complemented with simultaneous hot-wire measurements of the velocity field normal to the window at several points across its diameter. The tests were run for a fixed elevation for several azimuthal angles over a range of Mach numbers. The results provide the levels of unsteady optical aberration across the window; as well as the local thickness; intensity; and convective speed of the separated flow over the window. Results reveal that the optical distortions grow approximately with the square of the incoming Mach number multiplied by the freestream density; OPDrms; ∼; ρM2; as well as with the changing character of the aberrating flow with azimuth angle;
