Paper Abstract

A solar adaptive optics system is developed for the 60 cm domeless solar telescope of the Hida Observatory in Japan. It is designed for compensating low order turbulence in G-band using a 52-electromagnetic-actuator deformable mirror, a 6x6 Shack-Hartmann wavefront sensor and standard personal computers. The details of the system, particularly features of the deformable mirror are described. Laboratory experiments show that the use of adaptive optics raises the Strehl ratio by a factor of five for turbulence of under 99Hz. In solar observations, the improvement of resolution in long-exposure images with the adaptive optics system is demonstrated.
