We report a novel "cone-ray" model of background-oriented schlieren (BOS) imaging that accounts for depth-of-field effects. Reconstructions of the density field performed with this model are far more robust to the blur associated with a finite apertu

In this study, we investigate a Data Assimilation approach for the numerical reconstruction of turbulent aero-thermal flows, and more particularly of their average density fields. The proposed approach relies on an ensemble Bayesian inference method
