Aero-Optics Effects due to Turbulence

Optical signal attenuation caused by the flow field has be examined and compared to a low turbulence compressible flow reference case. Optical Path Difference (OPD) measurements show the effect of vortical scales on signal attenuation.

Turbulence conditions were generated by the manipulation of the boundary layer flow prior to flow separation.

The OPD was recorded and presented in terms of a Strehl ratio for air flowing at Mach 0.6 separating from a backward facing.
