| Abstract: | An adaptive optics (AO) system for solar observations at the Hida Observatory is described, which is composed of commercially available low-cost devices and fully controlled with software in standard personal computers. This AO system operates at a frame rate of more than 250 Hz by virtue of the image processing procedures used. From laboratory experiments, it was confirmed that this AO system was useful for the temporal wavefront-variation of less than 64 Hz. During solar observations at the Hida Observatory the AO system worked well, except for a few cases. |
