We are excited to announce that our latest research on high-speed imaging has appeared in Publications of the Astronomical Society of Japan (PASJ).

A joint research team led by Yamagata University has achieved ultra-fast imaging with an in-house high-sensitivity GAPD array camera named IMONY. Initial performance was demonstrated through astronomical observations with the Seimei Telescope at Kyoto University’s Okayama Observatory, where individual optical pulses synchronized with the rotation of the Crab Pulsar were successfully detected. Daiphys Technologies LLC participated from the early stages of the project, contributing to the design, development, and performance evaluation of the experimental system.
