The images formed under incoherent illumination by two gratings in tandem are analyzed using the theory of grating imaging. The images are categorized on the basis of various integer parameters that arise in the analysis. A transfer function is introduced for describing the imaging process. The image positions are related to the foci of a Fresnel zone plate.
