Outline of Final Research Achievements

Extreme Adaptive Optics (ExAO) that corrects wavefront aberration due to the atmospheric turbulence in real-time is crucial for spectroscopic observation of extraterrestrial planets with the next generation ground-based large telescopes such as Thirty Meter Telescope (TMT). In this study, we successfully developed a prototype of the extreme adaptive optics in the room and also proposed a new type of wavefront sensor, which characterizes the performance of the adaptive optics. The developed adaptive optics will be applied to the new telescope built in Okayama prefecture in future.
