Presenter: Mikio Kurita (Kyoto University)

A 3.8 m segmented telescope is planned to be built at the Okayama Astrophysical Observatory by the joint program among Kyoto university, Nagoya university, NAOJ, and Nano-Optonics Energy Inc. This is the Japanese first segmented telescope whose primary mirror is composed of "petal-shaped” 18 segment mirrors. The operation will be started in beginning of 2015 and dedicated for time domain astronomy with half of the telescope time and for joint use program among the universities with the rest.
We newly developed advanced technologies; rapid process and metrologies for the optics, an optimization program for weight reduction of the telescope, and segmented mirror control system. We will introduce these techniques briefly.
