A recent diagnostic advance applied to an ongoing experimental study of the evolution of shock-accelerated, heavy-gas cylinders has led to time-resolved concentration-field data with high enough spatial resolution to visualize developing secondary instabilities in detail. This data has allowed us to develop a reliable physics-based metric that is used to characterize the temporal evolution of the instabilities and to compare them with the results of numerical simulations.
