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 μm-μs 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.
时分辨射线成像具有突出的科学价值,但要实现这一目标,需要高密度的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铁和插入器件提供的多色光通量密度足以实现空间-时间分辨率高达 μm-μs 范围的硬 X 射线成像。在同步加速器光源上常用的现有间接 X 射线图像探测器可以通过采用市场上现有的基于 CMOS 的数字高速相机来适应快速图像采集进行改进。来自生命科学和材料研究的选定应用突出了这种高速硬 X 射线微成像方法的巨大潜力。
