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.

Summary

For digital holography (DH) and comparative digital holography (CDH) computer addressable modulators are needed. To ensure high quality reconstructions with good diffraction efficiency the modulators’ properties have to be known. Therefore a characterization of the modulators with respect to amplitude modulation, phase modulation, diffraction efficiency and surface geometry is required.
