| Description | We show that the phenomenon of self-imaging of infinite periodic gratings, known as the Talbot effect, is related not only to the dimensions of an elementary cell of the grating but is also closely connected with its structure. This is demonstrated in a particular class of gratings for which the self-imaging distance differs from the Talbot length as it is usually defined. This phenomenon can be explained by a destructive interference of several fractional Talbot images at the self-imaging distance. |
