Abstract:
A method for producing a three-dimensional image, comprising the steps of:simultaneously modulating a--preferably spatially coherent--light beam by a video signal containing three-dimensional image information; anddirecting the modulated light beam to pixels (image points) defining a first light emitting surface;emitting a component of the light beam from the pixels within a predetermined angle of view (field of view) in the different view directions, with an intensity corresponding to the three-dimensional image,directing the modulated light beams to the pixels from different entry angles, depending on the emitting angles within the angle of view, characterised bydirecting the light beams modulated corresponding to the different directions to the pixels of the first light emitting surface from one or more light emitting points of a second light emitting surface, said second light emitting surface being spaced apart with a predetermined distance from the first light emitting surface.
