Abstract

This paper presents an analysis of the predicted performance of Microwave Kinetic Inductance Detectors (MKIDS) in interferometric instruments. MKIDS are energy sensitive photon counting detectors which can be designed to operate over a wide range of photon energies, and have excellent timing capabilities. Several Optical and near-IR (OIR) MKID instruments have already been used on-sky, and there are ongoing developments in the US and Europe to improve their capabilities for a wide range of science cases. For interferometric instruments the benefits are clear, with no read out noise or dark current, and time resolution of a microsecond, they can be used for both fringe tracking and science detectors. The inherent energy resolution allows for a range of potential improvements to instruments, from rejection of stray light and cosmic rays, to improved wavelength coverage, to simplified optical designs with few, or no, moving elements.
