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.
我们探讨了在非相干系统中实现具有纵向周期性的带通滤波的可能性。推导了空间滤波具有纵向周期性的必要条件。结果表明，以开口比小的菲涅耳波带片作为光瞳的双光瞳系统中可以实现具有纵向周期性的带通滤波。
