A high resolution 3D color display, particularly suited to natural three-dimensional representation in computer tomography, is diclosed. In a digital autostereoscopic display, over eighty related or desired perspective views of an object may be represented in 3D, written onto a digital display by lasers in a few minutes, and subsequently deleted. The displays are digitally stored in minute fields of a thin LC layer of a scatter screen and converted into high resolution color pictures by reverse irradiation view color and brightness masks. The individual perspectives may be viewed selectively by a lenticular screen plate. The same displays may also be stored in the same code on a film which, when used in place of the scatter screen, shows the display to a user. The display can therefore be used in modified form to produce display photos when graphic computers are used.
A 3D-display, comprising a lens raster plate (1) with vertically disposed cylindrical lenses, a color mask (2), a brightness mask (3) and a micro-display (4, 7) having binary coded micro-fields (10) with a magnitude of a few μm2, said vertical lenses having foci being located on said micro-display (4, 7), said micro-fields (10) being determined from a computer for correct perspective views, and a binary code for said micro-fields (10) being selected from a group of codes including transparent or absorbing, transparent or scattering, bright or dark and horizontally or vertically polarised fields.
