Abstract
Methodologies for the experimental measurement of three-dimensional instantaneous density fluctuations via tomographic background-oriented schlieren (TBOS) were assessed using synthetic background images, corresponding to experimental measurements of a heated turbulent jet. Filtered back projection and iterative algebraic reconstruction algorithms were explored. Results show a superior reconstruction when the solutions from filtered back projection were used as an initial solution to a masked and windowed iterative algebraic reconstruction. The influence of the number of cameras and the wavelength of density fluctuations are both investigated.
