Binary Gabor zone plate encoded holography in mid- and far-infrared region

摘要

A new technique is developed to image IR sources by holography using a binary Gabor zone plate. The hologram consists of superimposed shadows of the binary Gabor zone plate cast by IR sources. The reconstruction is carried out by using Fast Fourier Transforms. The scaling produced by the zone plate encoded technique is indicated and a correction for this can be easily made using a computer. In this way, a true IR image in 3D can be obtained.
