Paper Abstract

We report some characteristic features concerning informative properties of the periodic and quasi-periodic light fields. On the basis of the sampling Fresnel-Dirac transformation, the idea of Fresnel periodicity is defined. Periodic or quasi-periodic light fields revealing this type of symmetry have properties of lensless imaging and self-restoration, such as the elimination of lattice defects-vacancies or inclusions, correction of quasi-periodic structures, and extraction of the common part of elements.
