Recently, we developed a new 4D X-ray characterization technique based on the multibeam X-ray imaging system. Thirty-two incident X-ray beams in a wide angular range of around ±73 were created by four Si crystals located on three confocal hyperbolic benders with different focal distances. And all the beams were captured simultaneously by lens-coupling detector systems. The CT was reconstructed by the standard Filtered Backprojection (FBP).
In this presentation, we report the developed high-speed 4D X-ray tomography technique. A dynamic process of bending the tungsten wire was reconstructed successfully with a temporal resolution of 1 ms. It is not necessary to rotate the sample, X-ray source, or detector at a high speed. We believe the in-situ and in-vivo measurement of the high-speed dynamic phenomenon and the unrepeatable process can be conducted such as living beings’ behaviors, the fluid motion, the deformation and fracture behaviors in the material science, and so on.
