Imaging properties of the Gabor superlens

A superlens is an optical system consisting of a pair of microlens arrays in which there is a slight difference in pitch. The relative displacement of one lens with respect to its partner causes the bundle of light passing through a pair of lenses to be deviated in such a way that all bundles converge to a common point and the system behaves like a lens. The focal properties are very different from those of a conventional lens and were originally described by Gabor in 1940. We have extended his analysis and have taken advantage of modern technology to assemble superlenses and confirm their properties experimentally.
