Digital image correlation has become a popular technique for making full-field measurements during high-rate mechanical testing, blast experiments, and shock loading; however, limited work to date has been done to evaluate the fidelity of this diagnostic tool. The aim of this work is to understand the underlying elements of uncertainty that affect the collected data. A methodology is presented for characterizing imaging system resolution and quantifying error when measuring out-of-plane displacements. High-velocity impact experiments were then performed on 6.35 mm thick aluminum disks to demonstrate the efficacy of digital image correlation when characterizing a ballistic impact.
