Abstract

During the last few years it has been shown that speckle masking observations with large telescopes can yield diffraction-limited images in spite of image degradation by the atmosphere and by telescope aberrations1-4. 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 masking5,6. For example, a 10-km array on earth can yield images with the fasci-nating resolution of 10^-5 arcsec. Labeyrie has for the first time shown that it is possible to combine the Coude beams of two telescopes coherently.
