The multibeam X-ray imaging system was developed to avoid sample rotation in high time-resolution X-ray tomography using synchrotron radiation. White X-rays are split into multiple X-ray beamlets by the Bragg reflection of Si crystals in the multibeam X-ray optical system. Since beamlets enter the sample from multiple angles, it is possible to obtain the number of projection images needed for reconstruction at a time.In previous systems, the beamlets drift was caused by torsion and heat in the optical system. In this study, the beamlets drift was reduced by improving the optical system, enabling reconstruction of a sample with complex structures such as insects.
