Laser Interferometric Computed Tomography (LICT) measurement is practically useful method to measure quantitatively supersonic unsteady flow field, and threedimensional (3D) density distribution is obtained. In our previous study, the 3D flow fields have been observed by LICT measurement. However, it is still difficult to measure 3D density distribution of the different times in CT reconstruction technique (4D-CT). In this study, to realize the novel 4D-CT measurements, high-speed camera is applied to our LICT measurement. This is because successive images at sufficiently short intervals can be obtained by high-speed camera.
