The study of shock wave is of significance in understanding supersonic flow. In this paper the three-dimensional (3D) quantitative measurement unsteady and discharging of shock waves is described. Three-dimensional shock-vortex flow field has been investigated by Laser Interferometric Computed Tomography (LICT) measurement with a diaphragmless shock tube in our laboratory. The complex flow field induced by discharging unsteady shock waves from three cylindrical holes can be successfully measured by pulsed LICT with Algebraic Reconstruction Technique (ART), and results are discussed.
