The aim of this communication is to describe a visualization technique allowing the reconstruction of holographic images of 3D, colored and animated objects. The technique, using unidirectional multiplexing, consists of dividing a master hologram into several horizontal strips, each of them being one different holographic recording of sequential views of a moving object. The holographic image is reconstructed by the second hologram. This process has been applied to reflection holograms of animated portraits reconstructed in white light. In this case pulsedlaser is necessary. In order to extend the process to polychromatic images, a simulation by motion synthesis has been carried out,allowing the use of CW lasers. Two directions have been explored : i) by adapting the well known rainbow transmission holographic technique, applied to two or three wavelengths. Unfortunately the number of viewers is limited to only one, set close to the second hologram ; ii) by using transmission holograms (master and second ones) recorded and reconstructed in coherent light with two or three different wavelengths. This somewhat restrictive technique (coherent reconstruction) allows therefore to increase the number of viewers. An experimental set-up using two lasers (Argon and Krypton) is developed. The different problems encountered are explained, especially the building of the "Cineholoscopes", i.e. holographic reconstruction apparatus including rotating optics and insuring a vertical scanning of the holograms by the reconstruction beam. The results of this study have led to an exhibition presentation of a multicolor, 3D, animated scene, for six viewers placed at a distance of ~ 2m from a 60 x 50 cm screen-hologram. This realization could be the starting point of a new technique of holographic display.
