What are the main findings? •Developed a lens-coupled high-speed X-ray camera, “Hayaka,” capable of highresolution imaging with a 1 µs minimum exposure time and a 5000 fps maximum frame rate. •Demonstrated high-speed energy scanning for QXAFS near the Cu K-edge in 0.5 s and achieved in situ 4D-CT observation of the somen noodle boiling process with a 0.5 s time resolution. What are the implications of the main findings? •The “Hayaka” camera system enables the observation of ultra-fast structural changes and chemical state transitions. •This high-speed 4D-CT technique opens newpossibilities for real-time, three-dimensional analysis of complex dynamic processes in food science and materials engineering.
