A multiple aperture approach for the correction of aero-optical distortions is presented. Measurements were conducted in Notre Dame's Tri-Sonic facility at M = 0.2 at 40kHz with an Ap/δ ≈ 6. In this work we investigated the convective nature of the wavefront in order to verify previous work as well as test the limits of a simply convective assumption. We present two models for wavefront correction, a simply convective model and a linear convolution approach. We found that for a separation ofdoi:10.2514/6.2017-1344 fatcat:xyypym2oz5hm3hoihc4ezjniue
