项目摘要

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.

为直接探测系外行星，研制了一种用于亚望远镜的八八分相掩模日冕仪。首先，制造瞳孔形透镜，以最大限度地提高斯巴鲁望远镜8opm日冕仪的可实现性能。基于光子晶体技术，设计并制作了1.6μm波段的8OPM。预计光子晶体掩模不仅可以用于地面观测，还可以用于未来的天基行星探测任务。此外，研制了一种精确测量低阶波前像差的日冕波前传感器。
