Extensive measurements of the optical environment around a generic hemisphere-oncylinder turret with a conformal window were performed for both forwardand backwardlooking elevation angles using a Malley probe, conventional 2-D wavefront sensor and highbandwidth 8x8 wavefront sensor for a range of Mach numbers from 0.35 to 0.45. A necklace vortex at the bottom of the turret and the shear layer structures formed in the separated region of the flow were identified as the main causes of optical distortions imposed on a laser beam. Different instruments provide different, but complimentary information about the aberrating structures. The Malley probe data can distinguish between stationary and traveling aberrations, but provides 1-D slices of wavefronts only, while the 2-D wavefront sensor data gives time-uncorrelated sets of highly spatially resolved wavefronts. The highbandwidth, 8x8 wavefront sensor data provides a unique opportunity to decompose wavefronts into their stationary and convective components. Oil-flow visualization revealed a complex topology of the flow around the turret.
