Abstract

We describe four-facet volume phase-transmission holograms made with DuPont photopolymer. The holograms implement light-efficient two-dimensional perfect shuffles based on a one-copy algorithm previously described by us [Appl. Opt. 31, 5464–5467 (1992)]. We have improved the real diffraction efficiency of these facet holograms to 65.5%, and we have improved the geometrical accuracy of the output over previous implementations by changing the experimental setup and the orientation of the hologram. We describe the procedures for making the holograms and give experimental results.
