Paper Abstract

An optical system, which can generate digital holograms of Rainbow type and Lippmann type, is proposed. In this system, a micro-imaging system is applied for reducing the digital image patterns to achieve about 0.45 micron optical resolution for rainbow hologram recording, and resulting about 90 degree viewing angle for the Lippmann hologram. The system is designed for both of Lippmann and Rainbow hologram recording mode through simply turning keyswitches. A fully functioning software is applied to calculate digital fringe patterns and control the entire equipment. Both types of holograms, Rainbow and Lippmann types, are recoded from calculated optical images so that it could be much easier to combine 2D or/and 3D or more multiplex optical data into one hologram through a simple working plan of art design to achieve a high resolution true color hologram. Applications for the digital Rainbow hologram include CGH, anti-counterfeiting security label, 3D display, etc, and 2D/3D true color holographic stereogram image for the Lippmann type recording mode. With this single process synthesizing system, it is considered as a fully functioning hologram printer. Examples of both of true color rainbow and Lippmann holograms are presented.
