摘要

To realize the temporal 4D-CT measurements, a high-speed camera has been applied to the LICT measurement. The projection data of different instants of time can be acquired from multi-directional series of images photographed by a highspeed camera. The 3D density fields of different time cases can be acquired from these projection data. The DCSI shows several unsteady phenomena, for example, the primary shock wave, the secondary shock wave, the transmitted shock wave and the vortex. It is possible to get temporal alteration of a shock wave phenomenon by comparing cross section of different time cases.
