The application of speckle masking to coherent telescope arrays can yield images with very high angular resolution. True images are obtained since speckle masking is a solution of the phase problem in speckle interferometry. For example, a 1-km array on earth can yield a resolution of 10-4arcsec at λ ≡ 500 nm. The fantastic resolution of 10-6arcsec can be obtained with a 40-km array in space at λ ≡ 200 nm. The authors show computer simulations of optical aperture synthesis by speckle masking. They describe simulations with a 10-telescope and a 4-telescope array (ESO VLT). Photon noise in the interferograms was simulated in all experiments.
