A movie film to provide a three dimensional image for the viewer is made by creating at each of a number of successive instants in time a number of simultaneous images of an object from a number of different viewpoints, using the number of simultaneous images to produce a composite hologram of the object for each particular instant, and recording the composite holograms representing the successive instants one after another in sequence along a film. To view such a film each composite hologram is moved into a field of view and illuminated in succession one after another at a rate above the flicker frequency of human observation. Each composite hologram creates a three-dimensional image of the object as seen from a number of different viewpoints and then the sequence of composite holograms enables the observer to follow movements of the object as this varies with time. |
