X射线塔尔博特干涉仪使用两个透射光栅，其优点是可以使用宽能量带宽的X射线。我们展示了使用白色同步加速器辐射与 X 射线塔尔博特干涉仪相结合进行高速 X 射线相位成像和断层扫描。莫尔条纹可见度超过20%，可实现定量相位测量。成功获得帧速率为500 f/s的X射线相位图像和扫描时间为0.5 s的X射线相位断层图。这一结果表明，对弱吸收 X 射线的物体（例如软材料和生物物体）进行时间分辨三维观察取得了突破。 (C) 2009 美国光学学会
X-ray Talbot interferometry, which uses two transmission gratings, has the advantage that broad energy bandwidth x-rays can be used. We demonstrate the use of white synchrotron radiation for high-speed X-ray phase imaging and tomography in combination with an X-ray Talbot interferometer. The moire fringe visibility over 20% was attained, enabling quantitative phase measurement. X-ray phase images with a frame rate of 500 f/s and an X-ray phase tomogram with a scan time of 0.5 s were obtained successfully. This result suggests a breakthrough for time-resolved three-dimensional observation of objects that weakly absorb X-rays, such as soft material and biological objects.
