Redundant versus nonredundant beam recombination in an aperture synthesis with coherent optical arrays.
Abstract
Signal-to-noise ratios for the amplitude of the object Fourier components are compared assuming either redundant or nonredundant beam recombination. A general condition is given for the object brightness below which redundant beam recombination is superior. A similar condition is found when the variance of the closure phases is considered.
