A Mach-Zehnder interferometer has been used for both flow-field visualization and quantitative assessment of aerodynamic parameters in a shock tube environment. Of special interest are the high- temperature effects in the post-shock region of bodies travelling at hypervelocity. Infinite-fringe interferograms give the density contours of the flow field and, in combination with an equilibrium real gas code, they can be used to provide information on the non-equilibrium state of the dissociating flow.
