A modification of the constant correction factor in the known equations of the background-oriented Schlieren is presented in order to be applicable to the nearfield. Near-Field background-oriented Schlieren has the Advantage over standard background-oriented Schlieren of being able to obtain reliable density distributions for Setups in which the background pattern is placed directly behind the investigated flow field. It is proven that the modified correction factor depends solely on the distance between the background pattern and the flow field and on the external shape of the investigated flow field itself. The proof of principle and the accuracy of the proposed technique are obtained by the simulation of a 2D density Variation with the u...
