上下文与无线电和亚毫米域相比，光学干涉成像仍处于起步阶段。由于现有阵列中的望远镜数量有限，图像生成是一个要求很高的过程，依赖于耗时的干涉仪阵列重新配置和超合成。目标。使用单模光纤将光从收集望远镜相干传输到焦平面，可以设计出新一代成像最佳的干涉仪。方法.为了支持这一主张，我们报告了OHANA伊基项目的成功完成：作为OHANA项目的一部分，围绕近红外单模光纤构建的双望远镜干涉仪的端到端的天空演示。结果在证明了单模光纤的相干传输是可行的之后，我们探索了一种新的成像设备的概念、性能和局限性，该设备以单模光纤为核心：用于长基线成像合成的敏捷引导干涉仪（AGILIS）。结论. AGILIS有潜力成为下一代设施或更大项目的先驱，如行星形成成像仪（PFI）。
Context. In comparison to the radio and sub-millimetric domains, imaging with optical interferometry is still in its infancy. Due to the limited number of telescopes in existing arrays, image generation is a demanding process that relies on time-consuming reconfiguration of the interferometer array and super-synthesis. Aims. Using single mode optical fibres for the coherent transport of light from the collecting telescopes to the focal plane, a new generation of interferometers optimized for imaging can be designed. Methods. To support this claim, we report on the successful completion of the ‘OHANA Iki project: an end-to-end, on-sky demonstration of a two-telescope interferometer, built around near-infrared single mode fibres, carried out as part of the ‘OHANA project. Results. Having demonstrated that coherent transport by single-mode fibres is feasible, we explore the concepts, performances, and limitations of a new imaging facility with single mode fibres at its heart: Agile Guided Interferometer for Longbaseline Imaging Synthesis (AGILIS). Conclusions. AGILIS has the potential of becoming a next generation facility or a precursor to a much larger project like the Planet Formation Imager (PFI).
