Abstract

ULTIMATE-Subaru is an on-going project at the Subaru Telescope for the next-generation wide-field infrared astronomy. The adaptive secondary mirror optically conjugated close to the ground level, is an important subsystem of ground-layer adaptive optics. Because the ground-layer is the dominant component in the total atmospheric turbulence existing near the aperture of the telescope, the correction of the ground-layer turbulence improves the seeing size over a wide field-of-view. The design together with the plan of the Subaru ASM including the interface to the telescope and the calibration strategy is presented.
