Paper Abstract

Focalized patterns generated at fractional Talbot distances of periodic phase gratings are discussed employing the Fresnel diffraction approach. Conventional and non-conventional focalizing cells are distinguished. The phase reliefs that generate patterns with maximum compression ratio, at a given distance, are described. Emphasis is done in the cases for which the 'resolution limit' of the focalized pattern is smaller than the normally expected one.
