Copying Technique for Making 2D Master Rainbow Holograms Using Non-Coherent Light
A technique of making 2D rainbow master holograms for embossing using non-coherent light source is described.In master hologram recording process, an uv-lamp is used as the light source, and no optical elements and anti-vibration devices are required. The color encoding is realized by fringe replication from the “rainbow plates”, in which the slit images are recorded.The “rainbow plates” can be used for many times, so the recording process of master holograms is very simple. The technique has the advantages of low investment, high production efficiency and good hologram quality. Therefore it is valuable for hologram mass production.
