Talbot interferometer using synchrotron radiation white beam has been demonstrated for time-resolved X-ray phase imaging and tomography of dynamic phenomena. Stroboscopic X-ray phase imaging based on Talbot interferometer which are applicable to visualization of periodic processes in soft materials with µs order temporal resolution is reported.
We performed stroboscopic X-ray phase tomography with X-ray Talbot interferometer using white synchrotron radiation. Stroboscopic X-ray phase tomography was demonstrated for a sponge with concertina moving at 24 Hz with 10 mm stroke. The rotation stage was moved at 53 s per a three-turn and 212 projections were acquired to construct a tomogram at specific phases of motion. 12 phases of concertina movement of tomograms were generated.
