Abstract
This paper describes an application of 3D density reconstruction from a limited number of Background Oriented Schlieren (BOS) images in a large high speed wind tunnel. The tested flow is a counter-flowing hot jet facing the transonic main flow. Ray deviation maps captured by 12 synchronized cameras are combined to reconstruct the three dimensional density field of the jet, in the line of the direct 3D BOS technique proposed by ONERA.
