摘要

In this paper an electron microscopic image of diameter 80 – 120 nm and of dimensions 180×220 pixels is used as a test object to fabricate Fresnel zone plate hologram. The author proposes a different set of pupils: one pupil still being a delta function and the other being a function of = sqrt(x2+y2). The obtained reconstructed images in case of scanning holography are investigated.
