A joint Talbot effect with two separated and crossed gratings of substructures is proposed. The mutual coupling in the joint self-imaging leads to a mechanism for the formation of the new moiré patterns. The conditions are studied for generating the logic-operated moiré fringes. Both theoretical analyses and experiments are given.
