Abstract
Shows that the second probability density function of a stellar speckle pattern observed at the focus of a large telescope can be used for imaging double and multiple stars. A mathematical description of the second probability density function is made for a double star. The theoretical model makes use of a double statistic: the well known negative exponential law is assumed for the first probability density function of the speckle pattern for a single unresolved star, and Poisson statistics are used for photon detection.Keywords
