Proceedings PaperCompact white-light-transmission hologram display and the design for a full-color version using diode lasers

A compact display was designed for white-light-transmission (WLT) holograms (30 cm X 40 cm). The unit, measuring 40 cm X 40 cm X 15 cm, contains a tungsten halogen bulb and a folded play-back beam, providing an aesthetically pleasing alternative to the usual large space needs of WLT holograms. The inevitable availability, in the near future, of red, green and blue diode lasers will bring the possibility of their use in the play-back of full-color transmission holograms. In this paper I explore the recording and playback requirements as well as several approaches for future display designs.
