A device is disclosed for representing two moving images. For that purpose,
two image generators (14, 16) are arranged at a 90~ angle to one another and
are oriented towards a beam splitter (22). A concave mirror (24) and a Fresnel
lens (26) are located at the sides of the beam splitter (22) opposite to the
image generators (14, 16). An observer sees two images floating freely in
space one behind the other. The images may for example be a publicity film and
a corporation logo.

A cet effet, deux générateurs d'images (14, 16) sont agencés de façon à former un angle de 90· l'un par rapport à l'autre et sont orientés dans la direction d'une lame séparatrice (22). Un miroir concave (24) et une lentille de Fresnel (26) se situent des côtés de la lame séparatrice (22) opposés aux générateurs d'images (14, 16). Un observateur voit deux images flottant librement dans l'espace l'une derrière l'autre. Ces images peuvent être par exemple un film publicitaire et le logo d'une entreprise.
