Paper Abstract

During the last few years it has been shown that speckle masking observations with large single-dish telescopes can yield diffraction-limited images in spite of image degradation by the atmosphere and by telescope aberrations. Much higher resolution can be obtained if the Coude beams of many telescopes are combined coherently in a central station and if the obtained long-baseline speckle interferograms are evaluated by speckle masking. For example, a 10-km array on earth can yield images with the fascinating resolution of 10 arcsec. Labeyrie has for the first time shown that it is possible to combine the Coude beams of two telescopes coherently.
