Abstract: The objectives of this work were to develop a moire deflectometry system to visualize gun muzzle flowfield, to analyze the acquired data for insight into the physics of the flow, and to determine temperature distribution in the field. An algebraic reconstruction technique was used to solve the ill-posed, linear set of equations that result from a series expansion of the temperature field. Moire tomography was shown to be a viable technique for acquiring the data needed to reconstruct 3D gun muzzle temperature fields.!3
