Abstract
Over the past few years pupil-remapping interferometry has received growing attention [1,2]. Pupil remapping is a technique that involves collecting the stellar photons from the pupil plane of a telescope with a 2-dimensional array of single mode waveguides and reformatting them at the output so that the emerging beams can be interfered in the appropriate fashion. This interferometric technique is used in astronomy in order to achieve sub-diffraction limited imaging despite the turbulent atmosphere and builds on the highly successful bulk optics analogue aperture masking interferometry in a number of ways.
