Paper Abstract

For some applications it is not necessary to change the image content of a hologram but instead simply to turn it on and off (without modifying the illumination). We describe a device that operates in a switching manner utilizing transmission holographic recordings of any size by applying an electric field to holo-lithographically generated transparent electrode structures underlying a suitable modulating material. This technique is applicable to all existing formats for transmission holograms and may find use in heads up displays (HUD's), for animation and multiplexing of holograms and in data playback where the information has been holographically stored.
