Abstract

In this paper, we find out the distribution of diffraction field of a zone plate on the axis, obtain the conclusion that the diffraction intensity of a zone plate's foci are almost the same for the front several secondary foci and give a locus of the foci's intensity that declines slowly and gradually when going towards the plate along the axis.
