This project will prototype a new type of visible and infrared light interferometry: telescopes freely moving in a line 10s of metres in length and directing their light towards a central beam combiner. This is particularly well suited to sparse aperture optical interferometry from space, which can be used to resolve angular scales much finer than the world's largest monolithic telescopes. The ground based prototype will also be able to make a several key astrophysical observations of benchmark stars and stellar systems, including making precise polarimetric measurements of dust shells around bright stars.

该项目将原型制作一种新型的可见光和红外光干涉法：望远镜在长度10米的线上自由移动，并将其光引导到中央梁组合仪。这特别适合于空间的稀疏光圈光学干涉法，可用于解析角度比世界上最大的整体望远镜要细得多。基于地面的原型还将能够对基准恒星和恒星系统进行几个关键的天体物理观测，包括对明亮恒星周围的灰尘壳进行精确的极化测量。
