A method and apparatus (300) for making holograms includes a technique for exposing a film substrate (319) or other light sensitive medium to consecutive two-dimensional images, together representative of a three-dimensional system, to generate a three-dimensional hologram of the physical system. Low beam ratios are employed to superimpose multiple (20-300) images on the substrate (319). Each image is relatively weak, but the combination of the series of weak images ultimately appears as a single clearly defined hologram.
Méthode et appareil permettant de réaliser des hologrammes et consistant en une technique d'exposition d'un substrat sous forme de film ou d'un autre milieu sensible à la lumière à des images bidimensionelles consécutives, représentatives ensemble d'un système réel tridimensionel, pour obtenir un hologramme tridimensionel du système réel. On recourt à des rapports de rayonnement faible pour superposer des imgages multiples (20-300) sur le substrat (319). Chaque image est relativement faible mais la combinaison de séries d'images faibles se révèle finalement sous la forme d'un hologramme unique à définition nette.
