    Abstract
    We explore the possibility of realizing bandpass filtering with longitudinal periodicity in incoherent systems. The necessary condition for spatial filtering to be longitudinally periodic is derived. Results indicate that bandpass filtering with longitudinal periodicity can be achieved in a two-pupil system with Fresnel zone plates with a small opening ratio as the pupils.
