穿透辐射时间分辨成像具有突出的科学价值，但其实现需要高密度光子以及相应的快速x射线图像检测方案。第三代同步加速器光源的弯曲磁体和插入装置提供了足够高的多色光子通量密度，可以进行时空分辨率高达μ m- μ s范围的硬x射线成像。现有的用于同步加速器光源的间接x射线图像探测器可以通过采用市场上已有的基于cmos的数字高速相机来适应快速图像采集。从生命科学和材料研究中选择的应用强调了这种高速硬x射线微成像方法的巨大潜力。
Time-resolved imaging with penetrating radiation has an outstanding scientific value but its realisation requires a high density of photons as well as corresponding fast X-ray image detection schemes. Bending magnets and insertion devices of third generation synchrotron light sources offer a polychromatic photon flux density which is high enough to perform hard X-ray imaging with a spatio-temporal resolution up to the mu m-mu s range. Existing indirect X-ray image detectors commonly used at synchrotron light sources can be adapted for fast image acquisition by employing CMOS-based digital high speed cameras already available on the market. Selected applications from life sciences and materials research underline the high potential of this high-speed hard X-ray microimaging approach.
