“…We conducted laboratory experiments similarly to the conventional ones using a simulated atmosphere-telescope system [7][8][9][10] . In the simulated experimental system, a pinhole illuminated by a He-Ne laser was used as an object and wavefront error was induced by a membrane-type deformable mirror with 19 channels.…”

“…We are also developing a solar adaptive optics system for the 60 cm domeless solar telescope of the Hida Observatory in Japan 7-10 . Our previous AO system used a deformable mirror with 52 electromagnetic actuators, a Shack-Hartmann wavefront sensor with a 6x6-microlens array and standard personal computers 9 . In solar observations at the Hida observatory, it worked so as to suppress the image variation induced by atmospheric turbulence.…”

A solar adaptive optics system for the 60 cm domeless solar telescope of the Hida Observatory in Japan is developed. A high-speed deformable mirror with 52 electromagnetic actuators is newly used in an experimental adaptive optics system. The use of the mirror resulted in the improvement of Strehl ratios in laboratory experiments. In solar observations, the system worked well when solar granulation was used as a target for wavefront sensing. An adaptive optics system being developed for a vertical spectrograph of the domeless solar telescope is described.
