Paper Abstract

A generalization of Talbot effect to the case of a tapered GRIN medium for non-uniform illumination is considered and an analogy with the conventional lens-imaging formula is presented. Self-imaging positions are evaluated. Results on Talbot effect are applied to a particular case of a tapered GRIN medium with divergent linear taper function in order to show the dependence of self-image distances on taper function, illumination and periodic object a well as the variation of the transverse magnification with self-image number.
