Holographic rendering of off-axis intensity digital holograms is discussed. A
review of some of the main numerical processing methods, based either on the
Fourier transform interpretation of the propagation integral or on its linear
system counterpart, is reported. Less common methods such as adjustable
magnification reconstruction schemes and Fresnelet decomposition are presented
and applied to the digital treatment of off-axis holograms. The influence of
experimental parameters on the classical hologram reconstruction methods is
assessed, offering guidelines for optimal image rendering regarding the
hologram recording conditions
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
