Subaru Telescope —History, active/adaptive optics, instruments, and scientific achievements— Subaru Telescope

Abstract

9## Conclusion This paper records the history of Subaru Telescope from its beginning in the early 1980s until 2020 through the author’s perspective, while covering the engineering aspects and some of the scientific results that could be achieved through the evolving telescope. The key engineering of Subaru Telescope was the implementation of technology to enable active control of the optical shape of the primary mirror so as to provide the best image quality under varying gravitational and thermal conditions. Another important development of the adaptive optics system with a laser-guide-star f
