Abstract

This paper describes the implementation of a13; novel technique called Background Oriented Schlieren that13; can produce quantitative visualization of density in a flow.13; This technique uses only a digital still camera, a structured13; background, and inverse tomographic algorithms which13; can extract two-dimensional slices from a three-dimensional13; flow. This has been applied to obtain the density13; field for an axisymmetric supersonic flow over a conecylinder13; model. Comparisons with cone tables show13; excellent agreement.
