Stroboscopic X-ray Talbot interferometry that is applicable to time-resolved quantitative X-ray phase imaging of periodic processes in soft materials is demonstrated. The constraint in photon flux was overcome by employing the stroboscopic technique of repeatedly capturing an image of the object at a specific phase of motion and by using polychromatic X-ray sources. By utilizing white synchrotron radiation in conjunction with a high-speed CMOS camera, stroboscopic X-ray Talbot interferometry with a 3 μs temporal resolution was achieved. By incorporating a chopper into a laboratory X-ray Talbot-Lau interferometer, a 5 ms temporal resolution was achieved.
