Experimental simulation of stellar speckle interferometry

Some results obtained using speckle interferometry in a coherent optical system are shown with a synthetic diffuser generated by an m x n matrix of random integer numbers with zero average by means of a computer program and a microdensitometer. The photographic emulsion where the pixels are recorded in bleached in order to obtain a phase diffuser which resembles the effects produced by the atmospheric turbulence, The laboratory simulation of this speckles and the optical autocorrelations of both one and two objects are similar to some resolved stellar objects.
