The temporal resolution of X‐ray tomography, using a synchrotron radiation X‐ray source, has been improved to millisecond order in recent years. However, the sample must be rotated at a speed of more than a few thousand revolutions per minute, which makes it difficult to control the environment around the sample. In this study, a high‐speed rotation device has been developed, comprising two synchronized coaxial motors movable along the direction of the axis, which can stretch or compress the rotating sample. Using this device, tomograms of breaking rubber were successfully obtained at a temporal resolution of 10 ms.

具有 10 ms 时间分辨率的用于 X 射线断层扫描的高速旋转装置

近年来，使用同步辐射 X 射线源的 X 射线断层扫描的时间分辨率已提高到毫秒级。然而，样品必须以每分钟几千转的速度旋转，这使得很难控制样品周围的环境。在这项研究中，开发了一种高速旋转装置，包括两个可沿轴方向移动的同步同轴电机，可以拉伸或压缩旋转的样品。使用该设备，以 10 毫秒的时间分辨率成功获得了断裂橡胶的断层图像。
