Abstract:The dynamic recording range or the maximum index modulation obtainable in any holographic material limits the properties of the hologram. The product of the modulation times the thickness determines diffraction efficiency in any phase hologram. In a reflection hologram low uniform modulation yields narrow spectral and angular bandwidths and high modulation in a chirped siructure yields high angular and spectral bandwidths. An ideal master hologram requires a just right efficiency and very low noise to produce … Show more
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.
