N1 - Funding Information:
This project is already funded by the JSPS proposal. We are thinking C-RED ONE as a detector for the NIR WFS, and it will be delivered in 2020. The first light will be sometime in 2021∼2022.
Funding Information:
The development of ULTIMATE-Subaru is partly supported by the Japan Society for the Promotion of Science (Grant-in-Aid for Research 17H06129).The authors wish to recognize and acknowledge the very significant cultural role and reverence that the summit of Maunakea has always had within the indigenous Hawaiian community. We are most fortunate to have the opportunity to conduct observations from this mountain.

N2 - In this paper, we present our ongoing adaptive optics (AO) activities and future plans at Subaru Telescop toward the next 5-10 years and the extrem large telescope (ELT) era. AO188 has been operated since 2008 as a facility curvature-based single-conjugate AO (SCAO) system at Subaru Telescop. We are recently upgrading AO188 with recent technologies, such as real-time control software with high-performance computing technology, high-power TOPTICA laser system, and high actuator-count DM, to improve its AO performance and operability for the next 5-10 years. Also, a laser-tomography AO (LTAO) mode plans to be added to AO188 by installing additional 4 wavefront sensors (WFSs) behind AO188 to enhance the AO correction in visible wavelength. These upgrades are important also for development and validation of technologies toward the next facility ground-layer AO (GLAO) system at Subaru Telescope, called the ULTIMATE-Subaru project. The ULTIMATE-Subaru will develop wide-field near-infrared (NIR) instruments assisted by a wide-field GLAO correction to boost the wide-field capability of Subaru Telescope in NIR wavelength. The GLAO system will be driven by 4 laser-guide star (LGSs), 4 Shack-Hartmann WFSs, and an adaptive secondary mirror (ASM). The conceptual study of the GLAO system was completed in 201 is project and now we are going to move forward to the preliminary design phase. The first light of the ULTIMATE-Subaru will be at the Nasmyth infrared (NsIR) focus in 2025 and at the Cassegrain focus in 2027. In addition to these wide-field AO activities, we also are putting effort to high-contrast imaging capabilities with SCExAO, which is an extreme AO system (ExAO) placed behind AO188. SCExAO applies additional high-order correction after the AO188 correction and feeds diffraction-limited image to variety of modules in visible and NIR, optimized for a large range of science cases. SCExAO is also demonstrating new technologies, such as prediction control, sensor-fusion control, and high-speed control with GPU, toward future high-contrast imaging instruments for ELTs.
