We present a high-speed multi-beam X-ray imaging realized using a detector system and the recently developed multi-beam X-ray optics [Voegeli et al., Optica 7, 514 (2020)]. The detector utilized optical relay lenses and mirrors for connecting four scintillator screens to a CMOS camera, enabling the high-speed simultaneous acquisition of multiple projection images. We successfully acquired nine projection images in 0.5 ms with a spatial resolution of 70 μm. Dynamical behaviors of a light-bulb filament and a living ladybug were captured with a temporal resolution of 0.5 ms, demonstrating the potential for high-speed and high-spatial-resolution 4D X-ray tomography.
