Abstract

The development of laser communication technology between satellites and ground stations has been paid attention recently. On the other hand, the laser communication between satellites and ground stations is always affected by the atmospheric condition. We can compensate this effect by applying the technology of Adaptive Optics that is used for astronomical observation.

We started the development of Adaptive Optics for laser communication in NICT from 2019 and completed the manufacture of Adaptive Optics for Koganei 1-m telescope in 2021 fiscal year. We performed the initial inspection of the performance of this system in March 2022. Although it was just simulation using artificial light source in our inspection, we can confirm the performance of AO of Koganei 1-m telescope is enough to improve the fiber coupling efficiency. In this paper, we describe the detail of Adaptive Optics for laser communication in NICT.
