Double-pulse holography techniques were used to observe vibration patterns of an impact-loaded aluminum rod and a honeycomb panel, shock waves in a vacuum shock tube, and gun-barrel deformation and motion during firing. Radial barrel deformations of an M16 barrel of approximately 0.0002 inch were observed. Author
