Research Abstract |
Adaptive optics is a technique of correcting images degraded with terrestrial atmospheric turbulence in real time. In this study, we developed a solar adaptive optics system at the 60cm domeless solar telescope of the Hida observatory in order to make fine structures on the solar surface observable. We applied it to solar observations and then confirmed that the system worked well using sunspots or granules as a target. Moreover, we developed a wavefront sensing technique that is needed to widen the field of view within which wavefront correction is effective.
