Autofocusing in optical scanning holography
(Optical Society of America, 2009-12-01)
We present autofocusing in optical scanning holography (OSH) with experimental results. We first record the complex hologram of an object using OSH and then create the Fresnel zone plate (FZP) that codes the object constant ...
Fast numerical generation and encryption of computer-generated Fresnel holograms
(Optical Society of America, 2011-03-01)
In the past two decades, generation and encryption of holographic images have been identified as two important areas of investigation in digital holography. The integration of these two technologies has enabled images to ...
