Paper Abstract

Diffracted images with inverted depth were first reported by the authors where a lens or slit intermediated the white-light double diffraction process. The appearance of an image with orthoscopic relief was reported, generated with the same system consisting of simple straight line diffraction gratings. We report now that the generalization of the symmetry properties to bi-dimensionally defined diffracting elements eliminates the vertical astigmatism of the images.
