摘要激光干涉计算机层析成像（LICT）测量是一种实用的超声速非定常流场定量测量方法，可获得三维密度分布。在我们以前的研究中，三维流场已被观察到的LICT测量。然而，在CT重建技术（4D-CT）中，仍然难以测量不同时间的三维密度分布。在这项研究中，为了实现新的4D-CT测量，高速摄像机应用于我们的LICT测量。这是因为高速照相机能够以足够短的间隔获得连续图像。
Abstract 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.
