Abstract

We discuss the performance of a fiber-coupled image-plane interferometer in which one transports individual image-plane wavefronts point by point by means of bundles of single-mode fibers to a beam-combining station where such wavefronts are cross-correlated. We compute the SNR of image reconstruction under low-light conditions where the principal source of noise is the shot noise of photodetection.
