California Institute of Technology’s Department of Aerospace ( has recently added a new Phantom UltraHigh-Speed v1612 to its Explosion Dynamics Laboratory. Predominantly studying thermodynamics, chemical kinetics, fluid dynamics, and solid mechanics with rapid combustion and shock waves, the group led by Professor Joe Shepard will use the instrument to study the pressure and stress transients in autoinjectors during device actuation. More specifically, the camera will be used to measure the velocity/acceleration of the moving components and to visualize cavitation within the syringe. Additionally, the camera will be used to study the collapse of a large air/vapor bubble within a water-filled cone.
