| Research Abstract |
We developed an image post-processing method of improving solar images partially-corrected through an adaptive optics (AO) system. In our method, another wavefront sensor is added into the AO system, and a solar image and wavefront information are simultaneously observed using an external trigger. A PSF is estimated from the wavefront information and then the solar image is deconvolved to be improved. We applied our method to images observed with the domeless solar telescope of the Hida Observatory, and confirmed good restoration.
