An eight-octant phase mask (8OPM) coronagraph for the SubaruTelescope has been developed for direct detection of extrasolar planets. First,pupil-shaping lenses were manufactured to maximize the achievable performance of the8OPM coronagraph for the Subaru Telescope. An 8OPM optimized for the 1.6μm observational band was also designed and manufactured based on photonic crystal technology. It is expected that the photonic crystal masks will be useful not onlyfor ground-based observations but also for future space-based planet-finding missions In addition, a coronagraphic wavefront sensor for accurately measuring low-order wavefront aberrations was developed.

为Subaru望远镜制造了八颗相位掩模（8OPM）的冠状仅用于基于地面的观察，但对于未来的空间行星捕获任务，也开发了可准确测量低阶波沿畸变的Coronagraphic Wavefront传感器。
