Following the testing of a pathfinder hypertelescope in the southern Alps, versions usable on the Moon or in space are proposed. The large resolution gain expected for direct imaging in a narrow “Direct Imaging Field”, with a high limiting magnitude, is of interest for many astrophysical targets and for searching for exolife on nearby exoplanets. The much larger field-of-view obtainable with multi-field focal optics, for full-sky coverage in a few days of scanning, is suitable for searching, detecting, and tracking Potentially Hazardous Asteroids with a cluster of hypertelescopes.

用于直接高分辨率成像的月球或天基超望远镜

在对阿尔卑斯山南部的探路者超望远镜进行测试之后,提出了可在月球或太空中使用的探空仪。对于狭窄的“直接成像场”中具有高限制幅度的直接成像,期望获得较大的分辨率增益,这对于许多天体物理目标以及寻找附近系外行星的系外生命都非常重要。多场聚焦光学器件可获得的更大视场,可在几天的扫描中实现全天空覆盖,适用于通过超望远镜簇搜索,检测和跟踪潜在危险的小行星。
