This paper presents a cross-spectrum analysis technique, which makes it possible to measure submilliarcsecond shifts between two speckle patterns at two close wavelengths, and, then, to check the feasibility of the 'differential speckle interferometry' techniques proposed by Beckers. The measuring of micro-displacements as small as 1 milli arc s, produced by the atmospheric dispersion, is described and the results are presented and discussed in the cross-correlation space as well as the cross-spectrum space. Further astronomical applications of this technique in the field of high angular resolution are also considered.
