Recording of rainbow holograms using As₂Se₃ amorphous layers

Abstract

The simple method of phase-relief rainbow master-hologram recording using the only laser has been developed. In this method at both recording steps (a normal transmission hologram and phase-relief sunlight-viewable master hologram recording) the same inorganic chalcogenide photoresist and the same postexposure one-stage treatment are used. It results in more simple and cheaper process of master hologram fabrication.
