Hypertelescope interferometers having many highly diluted sub-apertures are capable of directly imaging, within a narrow field of view, celestial objects at a high resolution thanks to pupil densification. This Letter verifies with OpticStudio modeling the possibility of simultaneously imaging multiple such fields. A strategy of multi-field sampling uses a microlens array to generate multiplexed field channels, where independent active corrections of the tip-tilt and piston are applied for compensating for the off-axis aberrations. Adopting this strategy, we have designed a model of a multi-field hypertelescope with OpticStudio. The reported design expands the observing performance of hypertelescopes for directly imaging multiple sources with very high angular resolution.

具有多重视场的超望远镜

由于瞳孔密实，具有许多高度稀释的子孔径的超望远镜干涉仪能够在狭窄的视野内以高分辨率直接成像天体。这封信通过OpticStudio建模验证了同时成像多个此类场的可能性。多场采样策略使用微透镜阵列来生成多路复用的场通道，其中对倾斜倾斜和活塞进行独立的主动校正，以补偿离轴像差。采用这种策略，我们使用OpticStudio设计了一个多视场超望远镜的模型。报告的设计扩展了超望远镜的观察性能，可用于以很高的角分辨率直接对多个源成像。
