Abstract

A simple iterative algorithm for reconstructing the images of compact radio sources from very-long-baseline interferometry (VLBI) measurements of visibility amplitudes and "closure" phases is described. The method makes efficient use of redundant sampling of spatial frequencies by making a global solution of phase "closure" equations for a complete set of observetions.
