Paper Abstract

A generalization of the Talbot effect or the self-imaging phenomenon to a tapered gradient-index (GRIN) medium by Fourier Optics is considered. A new interpretation of this effect from the viewpoint of number theory as the output/input relationship between the integer and noninteger difference of position and slope of rays coming from a periodic object is presented. The Talbot effect is demonstrated inside a standar quarter-pitch selfoc microlens.
