Abstract
Developments of the background oriented schlieren technique (BOS) towards a three-dimensional measurement technique for 3D density fields are presented. The projections of the density are tomographically reconstructed using filtered back-projection. Theoretical investigations show that the sensitivity of the BOS method depends on the geometric setup, the resolution of the camera, the focal length of the lens and the evaluation algorithm whereas the resolution of the method is described by its transfer function. Applications of the method at an under-expanded free jet of air and to the wake of wind tunnel cascade showed good results - qualitatively as well as quantitatively.
