Charakterisierung von Flüssigkristalllichtmodulatoren für die Rekonstruktion digitaler Hologramme (Investigation and Qualification of Spatial Light Modulators for the Reconstruction of Digital Holograms)
Abstract
Für die digitale Holografie (DH) und die vergleichende digitale Holografie (CDH) werden computeradressierbare Modulatoren zur Hologrammrekonstruktion benötigt. Um qualitativ hochwertige Hologramme mit hoher Beugungseffizienz rekonstruieren zu können, müssen die Eigenschaften der Modulatoren genau bekannt sein. Dies macht eine Charakterisierung der Modulatoren im Hinblick auf Amplitudenmodulation, Phasenmodulation, Beugungseffizienz und Oberflächentopografie notwendig.
