Abstract

Highly magnified images of a periodic object placed in the close vicinity of the rectangular grating have been obtained by incoherent illumination. The imaging behavior has been explained quantitatively on the basis of the optical transfer function of the system. By advantageously using the high magnification involved, this phenomenon has been discussed for the purpose of precise displacement measurements. Furthermore, an explanation of Lau imaging has also been included as a spatial case of the phenomenon under consideration.
