Hypertelescopes: The Challenge of Direct Imaging at High Resolution

Abstract: Sparse optical interferometric arrays of many apertures can produce direct images in the densified-pupil mode, also called "hypertelescope" mode. Pending the introduction of adaptive optics for cophasing, indirect images can also be reconstructed with speckle imaging techniques. But adaptive phasing is preferable, when a sufficiently bright guide star is available. Several wave sensing techniques, byproducts of those used on monolithic telescopes for some of them, are potentially usable. For cophased direct im… Show more

“…Metamaterials emerged as the composite periodic medium exhibiting unusual electromagnetic properties [1], about a couple of decades ago. Ever since they have given rise to a plethora of different meta-concepts such as meta-materials, meta-structure [2], meta-mirror [3,4], metalens [5,6], meta-surface [7,8], meta-wedge [9], meta-barrier [10,11], meta-damper [12], metafoundation [13], meta-lattice [14], etc. Based on this evolutionary path, they can be defined as artificial materials which have been structurally engineered in such a way that their geometric and topological properties overtake their chemical and atomic properties for dictating their behaviour when interacting with various physical phenomena.…”
